九、發明說明： 【發B月所屬 < 技術領域】 技術領域 本發明係有關於一種馬達，該馬達係具有可安裝於洗 衣機等之固定部的定子、及可安裝於洗衣機等之驅動用轴 的轉子者。 【先前技術】 背景技術 習知馬達係使用於如第13圖、第14圖所示之習知滾筒 型洗衣機100等。滾筒型洗衣機100在洗衣機本體1〇1(以下 稱作本體101)内設有水槽1〇2及旋轉滾筒1〇4(以下稱作滾筒 104)。水槽102係藉由懸吊結構（圖未示）而彈性支撲於本體 101。滾筒104係設於水槽1〇2内，且形成有多數孔1〇3。而 且’滾筒104可藉由馬達1〇5旋轉驅動。門1〇6係可自由開閉 地設於本體101正面側。藉由將門106打開，便可經由水槽 102之正面開口部與滾筒1 〇4之正面開口部，自滾筒1 〇4内取 放衣物（圖未示）。 又’在將門106打開且把衣物投入滾筒1 〇4内後，再放 入洗滌劑，開始運轉洗衣機100。當洗衣機1〇〇開始運轉時， 會由給水部107給水至水槽102内。供給至水槽1 〇2内之水 (圖未示）可通過多數孔103進入滾筒104内，所需量之水也會 供給至滾筒104内。藉由馬達105以預定之旋轉速度旋轉驅 動滾筒104時，收容於滚筒104内之衣物就會被設於滾筒1〇4 内周面之攪拌突起108勾住，朝旋轉方向抬起，且朝旋轉方 向抬起之衣物會在適當的高度落下。藉此，可在衣物上施 加捶洗的作用，進行衣物的洗滌。在如此之洗衣行程進行 後，藉由排水部109將髒污之洗滌水排出至本體1〇1外部， 再使用重新供給之水執行洗清行程。洗清行程結束後會 藉由滾筒104高速旋轉執行脫水行程。該等洗衣行程、洗4 行程、脫水行程可根據預定之控制順序自動執行。 此種習知洗衣機已揭示於如日本專利特開平

可旋轉。藉此，可驅動滾筒4，執行洗衣行程、洗清行程、 脫水行程、烘乾行程等各行程。此外，固持部33亦可以樹 脂成形品構成。 定子5a具有定子鐵心20、定子樹脂模製部31(以下稱作 模製部31)、安裝部32及連接於線圈54之連接器27。定子鐵 心20係朝定子5a之徑方向延伸，且具有配列於周方向之齒 20a。定子鐵心20係構造成在齒2〇a安裝有線圈54。此外， 第5圖係顯示線圈54捲繞於周方向之環形線圈方式之馬達 5。又，轉子5b具有與齒20a對向之磁鐵22及與磁鐵22對應 之轉子鐵心23。藉此，電磁作用可在定子5a與轉子5b之間 產生作用，使馬達5旋轉。模製部31係使用樹脂材料可覆蓋 定子鐵心20地模製成形。 安裝機構30係由複數安裝部32及螺栓34等固接具類構 成。安裝部32係由複數安裝腳構成，且該等安裝腳係設成 相對於模製部31朝固持部33安裝之側之轴方向端面的外周 朝外側延伸者。螺栓34等固接具類可將安裝部32與固持部 33螺接在一起。又，固持部33與軸承部24係一體成形。輛 承部24中有用以支撐轴4a之軸承24a、24b及油封24c壓入。 此外，固持部33係其中一面安裝於水槽2，而安裝有水槽2 之面的背面側則安裝有定子5a。 各安裝部32設有安裝孔32a，固持部33設有螺孔33a。 1362809 藉由使螺拴34從固持部33之反面側穿過安裝孔32a，可使其 螺合固接於於螺孔33a。藉此，可固接安裝部32與固持部 33。結果，定子5a可穩固地安裝於水槽2背面。 又，轉子5b具有較38、磁鐵22、與磁鐵22對應之轉子 5鐵〜23。而且，轉子5b具有藉由樹脂材料模製成形之轉子 树月a模製部37(以下稱作模製部37)。模製部37係使用樹脂材 料，可覆蓋磁鐵22與轉子鐵心23地模製成形。模製部37具

與鍵槽（圖未示）可卡合之止旋部，來代替鋸齒部37bl、4al。 B而且，還使用固定墊圈39 ’藉由螺栓4〇等固接具類將轉子 5b相對於轂38固接於軸4a。藉此，轉子北可穩固地安裝於 軸4a。此外，將馬達5朝本體丨安裝之組裝順序可以有各種 選擇。又，止旋部、定子5a與轉子外之間的間隙定位部可 使用各式各樣的結構、方法。 20 又，本發明之洗衣機5〇中，滾筒4之轉轴方向係設成自 水平方向傾斜角度㈣±1〇度。藉此，與滚筒4係設置於水 平方向之洗衣機相比，可顯示出衣物相對於滾.之轉轴方 向容易聚集在低位置的傾向。除此種傾向性外還可大幅 地改善衣物之糾結、扭曲的發生，而可謀求提高機械力之 15 1362809 作動並且不易產生皺折。即’本實施形態之洗衣機50係有 關於使用控制基板9之滾筒4的驅動控制’且具有正逆弧形 旋轉驅動模式及正逆連續旋轉驅動模式。正逆弧形旋轉驅 動模式係在滾筒4之旋轉角度大於90度且小於180度的條件 5 下，交互反覆進行急正弧形旋轉及急逆弧形旋轉的旋轉驅 動模式。此外，在正逆弧形旋轉驅動模式中，滾筒4係以 40rpm〜60rpm左右之旋轉速度被驅動。又，正逆連續旋轉驅 動模式係以可實現藉由滾筒4之旋轉而抬起之衣物從衣物 本身重量勝過前述抬起力之高度落下的動作的旋轉速度來 1〇 旋轉滾筒4，滾筒4之連續旋轉係交互正逆反覆進行之旋轉 驅動模式。而且，可依需要來組合該等2個驅動模式加以執 行。 第12A圖到第12F圖係顯示當滾筒4内收容有模擬衣物 21時滾筒4之驅動模式。如第12A圖所示，從滾筒4之靜止狀 15 態，到如第12B圖所示，滾筒4進行大於90度且小於180度的 弧形旋轉。藉此，衣物21最高會被抬至大於90度且小於180 度。而且，藉由交互正逆進行該弧形旋轉驅動，在衣物21 之抬起最終地點或最終地點附近，滾筒4可產生因旋轉之反 轉的減速或制動狀態。藉此，如12C圖所示，藉由由於賦與 2〇 衣物21之旋轉慣性所生之強制剝離力與衣物21本身重量， 可從滚筒4内面確實且瞬時地剝落衣物21。然後，反覆進行 第12C圖到第12F圖所示之動作。即，如第12c圖到第12F圖 所示，藉由滾筒4之交互正逆弧形旋轉驅動，可在每次之孤 形旋轉驅動中，左右交替衣物21之抬起位置、落下位置。 16 1362809 藉由在此種驅動模式旋轉驅動滾筒4，可提高衣物21之分散 作用。而且，機械力可及於衣物21，而可有效地進行洗滌。 此外，第12G圖係模式性地顯示分別反覆進行9〇度之正逆弧 形旋轉時之正逆弧形旋轉驅動模式的模式圖。 又’在只有如第12A圖到第12F圖之正逆弧形旋轉駆動 模式中，可減輕衣物21之糾結、扭曲、皺折等，但另一方[Technical Field] The present invention relates to a motor having a stator that can be attached to a fixing portion of a washing machine or the like, and a driving shaft that can be attached to a washing machine or the like. The rotor. [Prior Art] A conventional motor is used in a conventional drum type washing machine 100 as shown in Figs. 13 and 14. The drum type washing machine 100 is provided with a water tank 1〇2 and a rotating drum 1〇4 (hereinafter referred to as a drum 104) in the washing machine main body 1〇1 (hereinafter referred to as a main body 101). The water tank 102 is elastically supported by the body 101 by a suspension structure (not shown). The drum 104 is provided in the water tank 1〇2, and a plurality of holes 1〇3 are formed. Moreover, the drum 104 can be rotationally driven by the motor 1〇5. The door 1〇6 is detachably provided on the front side of the body 101. By opening the door 106, the laundry can be taken out from the drum 1 〇4 via the front opening of the water tank 102 and the front opening of the drum 1 〇4 (not shown). Further, after the door 106 is opened and the laundry is put into the drum 1 〇 4, the detergent is placed again, and the washing machine 100 is started to operate. When the washing machine 1 starts to operate, water is supplied from the water supply unit 107 to the water tank 102. Water (not shown) supplied to the water tank 1 〇 2 can enter the drum 104 through a plurality of holes 103, and the required amount of water is also supplied to the drum 104. When the motor 105 is rotated to drive the drum 104 at a predetermined rotational speed, the laundry accommodated in the drum 104 is hooked by the agitation projections 108 provided on the inner circumferential surface of the drum 1〇4, lifted in the direction of rotation, and rotated. Clothing that is lifted in the direction will fall at an appropriate height. Thereby, the washing effect can be applied to the laundry to wash the laundry. After the laundry stroke is performed, the dirty washing water is discharged to the outside of the main body 1〇1 by the drain portion 109, and the washing course is performed using the re-supply water. After the end of the washing course, the dewatering stroke is performed by the high speed rotation of the drum 104. The laundry stroke, the wash 4 stroke, and the dehydration stroke can be automatically executed according to a predetermined control sequence. Such a conventional washing machine is disclosed in Japanese Laid-Open Patent Publication No. Hei 10-263271 (hereinafter referred to as "Patent Document"), JP-A-2002-431-5 (hereinafter referred to as Patent Document 2), and JP-A-2005 Japanese Laid-Open Patent Publication No. 2004-216166 (hereinafter referred to as Patent Document 4), JP-A-2000-254385 (hereinafter referred to as Patent Document 5), and the like. For example, the conventional washing machine has a first motor for performing a reverse rotation of the washing stroke and the washing stroke, and a second motor for continuously rotating in one direction for performing the dehydration stroke. The first motor can drive the rotary drum in the forward and reverse rotations of the first rotation number during the washing stroke and the washing stroke. In the dehydration stroke, the second motor can continuously rotate the rotary drum in one direction at the second rotation number. The i-th motor and the second motor are attached to the back surface of the water tank, and the rotational force is transmitted to the rotary drum by the v-belt. A driving method of such a rotary drum has been disclosed as in Patent Document 1. Further, a driving method for directly transmitting the rotation of the motor attached to the back surface of the water tank to the rotating shaft of the rotating drum is disclosed in Patent Document 2. Further, an inner rotor type motor in which a rotor is disposed on the inner circumference of a stator of a motor mounted on the back surface of a water tank is disclosed in Patent Document 3. Alternatively, a rotor type motor in which the rotor is disposed outside the outer circumference of the stator has been disclosed as disclosed in Patent Document 4. Thus, various methods have been used as a driving method for driving the rotary drum. Further, Fig. 13 shows a conventional drum type washing machine 100 using an inner rotor type motor 105. Fig. 14 is a view showing a conventional drum type washing machine 100 using an outer rotor type motor 105. In both of the drum type washing machines 100, the motor 105 is attached to the bottom surface of the rear surface of the water tank 102, and the rotor 111 is attached to the rotating shaft 112. Further, the structure in which the stator is attached to the outer bottom surface of the water tank is disclosed, for example, in Patent Document 3, that is, the stator and the rotor are molded by a resin material. The stator is formed with a mounting leg at a portion molded by the resin. The mounting feet are attached to the outside bottom of the sink with screws or bolts. Thereby, the motor is mounted on the outer bottom surface of the sink. On the other hand, after the dehydration stroke, the rotating drum performs several forward and reverse rotations within a small rotation angle of 9 degrees or less. In particular, the rotary drum 1〇4 performs several forward and reverse rotations at a small rotation angle of 10 degrees or more and less than 30 degrees. Thereby, the laundry attached to the rotary drum can be peeled off, and the laundry existing in the state of being gathered in the upper portion of the rotary drum can be dispersed. Further, it is also known that a structure in which the dehydration is eliminated can be eliminated, and a structure in which the laundry is removed after drying is disclosed as disclosed in Patent Document 5. In the structure accompanying the mounting of the motor toward the washing machine, the stator of the stator and the rotor of the rotor are in the predetermined two positions and that it is also checked whether proper motor characteristics are exerted. Relative production: 'As disclosed in Patent Document 5, when the motor interaction repeatedly performs a driving mode that is less than: money-shaped rotation, the motor is detected to switch the rotational position, and then the reverse control of the motor reverse drive is performed according to the position detection number. .

The rotation speed rotates to drive the pure cylinder 4, and the clothes that are contained in the drum are caught by the feeding protrusions 8 provided on the inner circumferential surface of the drum 4, and the clothes that are lifted in the rotation direction and lifted in the rotation direction are in the clothing The height falls. Thereby, it is possible to perform the washing action of the laundry on the laundry. After this laundry stroke is performed, the dirty washing water is discharged to the outside of the body 1 by the drain portion 11. After the decontaminated washing water is discharged, the water is re-supplied to the water tank 2, and the washing water is used to perform the washing stroke. 4 After the end of the clearing stroke, the drum 4 will be smashed at a high speed, such as 5 ,. Water training. The laundry stroke, the wash/monthly private (10) tree program can be automatically executed according to the predetermined control sequence. In addition, the real (four) red silk machine 5 () is a roller type washing and drying machine equipped with a nuclear trunk. That is, the chess trunk 13 can suck the inside of the water tank 2 by the blower 12; the working gas in the cylinder 4 can then sequentially heat the adsorbed air to remove the fishing unit μ and heat the heating unit 17. Thereafter, After the defrosting and heating, the air becomes dry high-temperature air, and the air is again supplied to the inside of the water tank 2 and the drum 4. The drying process is performed thereby. In addition, the material is automatically executed in the dewatering line (dry: private): Wh· The washing machine 5q of the embodiment constitutes a drum type washer-dryer. To automatically execute the above-described strokes, the control unit such as the control panel 9 can be automatically controlled according to the mode setting or control program of the operation panel. The motor 5, the water supply unit 7, the drain unit 11, and the drying unit 13. In this manner, the washing machine 50 has a robot that can automatically perform the washing stroke washing and dehydrating stroke, and for the dry ordering. Further, the control board 9 is equipped with a microcomputer. Jcap7 can be opened and closed by a solenoid valve (not shown), such as water supply path 61 as shown in the water supply path. In addition, the laundry (10) has available water supply, and timely wash the detergent storage unit (not shown) (four) Read the organization within 2. In the laundry line Tree, washing line (10) tree "When drainage is required, the drain portion U can be opened and closed by a solenoid valve (not shown), as shown by the drainage path 62. For the cadre 13 to be read by Wei Jizhen The circulation path 63β of the air circulation in the drum 4 Further, the drying unit 13 has a filter 15, a house removing unit 16, and a heating unit 1. The dust (4) can be introduced into the air from the water tank 2 and the drum 4 into the air. The air is removed and removed. The fishering unit 16 dehumidifies the air removed by the filter 15. The heating port can heat the air removed by the fishing unit 16 to produce a dry high temperature. The air blower 12 is disposed on the downstream side of the circulation path 63 with respect to the heating unit 17. Thereby, the blower unit 2 is less susceptible to moisture and improves reliability. Further, the drying unit 13 has an evaporator. The air conditioner 19 is configured by a condenser. The air conditioner 19 uses a compressor 18 to circulate the refrigerant to the dehumidifying unit 16 and the heating unit π, and exchanges heat with the air circulated by the drying unit 13. The structure of the cadre 13 is not limited to this. The drum 4 has been mounted on A rotating shaft 背面 (hereinafter referred to as a shaft 4a) on the back surface of the cylinder 4. A rotating shaft serration portion 4a1 (hereinafter referred to as a serration portion 4a1) is provided on the outer circumference of the front end of the shaft 4a. The shaft 4a is supported by the bearing portion 24 and is directly connected to the sink. 2 Motor 5 on the back side. The shaft 4a is provided together with the drum 4 and the water tank 2, and the direction of the rotation axis is inclined from the horizontal direction to the bottom side by the angle of 1362809 V degrees θ = 20 ± 1 〇. When the drum 4 is disposed obliquely as compared with when the drum 4 is disposed in a direction parallel to the horizontal direction, even if the drum 4 is provided at the same height ', it is opened obliquely upward. Thereby, the user of the washing machine 50 does not need to take It is easy to pick and place clothes in a posture that is barely bent. In particular, from the experience of the inventor* 5, it is possible to obtain even children (except young children) by tilting angle Θ 20 ± 10 degrees. The difference in height between adults and, in addition, the wheelchair user's structure is the easiest to carry out the laundry. Further, since the water supplied to the drum 4 is collected on the back side of the drum 4, there is an advantage that a deep water storage state can be obtained even with a small amount of water. Further, the washing machine 50 shaft 4a shown in Fig. 1 is directly connected to the motor 5 attached to the back surface of the drum 4. Thereby, the motor 5 can directly transmit the rotational force to the drum 4. Further, the configuration of the shaft 4a and the motor 5 is not limited to the configuration shown in Fig. 1. Moreover, the 'washing machine 50 may constitute a drum type washing and drying machine having a drying function, and may also be a drum type washing machine 50 having no drying function, a drum type 4 silk drum 15 straight drum type washing machine 50, and another washing machine 50 without a drum 4 or the like. . Further, the present invention can be applied regardless of the manner in which the motor 5 is attached to the washing machine 5 depending on the washing method of the washing machine 50 or the driving method. Further, the drive shaft 4a for rotating the rotor 5b does not particularly affect the support structure of the shaft 4a or the rotation of the drive object to the drum 4 or the like. Further, the motor 5 has a stator 5a and a rotor 5b. Further, the stator 5 & can be attached to the stator holding portion 33 (hereinafter referred to as the holding portion 33) by the plurality of mounting mechanisms 30 disposed in the circumferential direction of the stator 5a. The holding portion 33 is constituted by a metal fixing sub-mount that is fixed to the back surface of the water tank 2 by a bolt fixing device (not shown), and the motor unit 55 can be constituted by the motor 5 and the holding portion 33. Further, the rotation force can be transmitted to the shaft 4a of the drum 4 to be fixed to the rotor 5b. By the electromagnetic action by the three-phase alternating current acting between the stator 5a and the rotor 5b, the north hand can be rotated. Thereby, the drum 4 can be driven to perform each stroke such as a washing stroke, a washing stroke, a dehydration stroke, and a drying stroke. Further, the holding portion 33 may be formed of a resin molded product. The stator 5a has a stator core 20, a stator resin molded portion 31 (hereinafter referred to as a molded portion 31), a mounting portion 32, and a connector 27 connected to the coil 54. The stator core 20 extends in the radial direction of the stator 5a and has teeth 20a arranged in the circumferential direction. The stator core 20 is configured such that a coil 54 is attached to the teeth 2A. Further, Fig. 5 shows a motor 5 in which a coil 54 is wound around a toroidal coil in the circumferential direction. Further, the rotor 5b has a magnet 22 opposed to the tooth 20a and a rotor core 23 corresponding to the magnet 22. Thereby, the electromagnetic action acts between the stator 5a and the rotor 5b to rotate the motor 5. The molded portion 31 is molded by covering the stator core 20 with a resin material. The mounting mechanism 30 is composed of a plurality of fixing members such as a plurality of mounting portions 32 and bolts 34. The mounting portion 32 is composed of a plurality of mounting legs, and the mounting legs are provided to extend outward with respect to the outer periphery of the axial end surface of the side where the molding portion 31 is attached to the holding portion 33. A fixing member such as a bolt 34 can screw the mounting portion 32 and the holding portion 33 together. Further, the holding portion 33 and the bearing portion 24 are integrally formed. The bearings 24 are used to press the bearings 24a, 24b supporting the shaft 4a and the oil seal 24c. Further, one end of the holding portion 33 is attached to the water tank 2, and the stator 5a is attached to the back side of the surface on which the water tank 2 is attached. Each of the mounting portions 32 is provided with a mounting hole 32a, and the retaining portion 33 is provided with a screw hole 33a. 1362809, by screwing the thread 34 from the opposite side of the holding portion 33 through the mounting hole 32a, it can be screwed and fixed to the screw hole 33a. Thereby, the mounting portion 32 and the holding portion 33 can be fixed. As a result, the stator 5a can be stably mounted to the back of the water tank 2. Further, the rotor 5b has a rotor 45, a magnet 22, and a rotor 5 corresponding to the magnet 22. Further, the rotor 5b has a rotor a month molding portion 37 (hereinafter referred to as a molding portion 37) molded by a resin material. The molded portion 37 is formed by molding a resin material and covering the magnet 22 and the rotor core 23. The molded portion 37 has a top portion 37a provided on the opposite side of the water tank 2. A central portion 38 of the top portion 37 & is formed by inserting a metal hub 38. The hub 38 is formed with a mounting hole 37b in the center portion of the top portion 37a by fitting, and a rotor serration portion 37b1 (hereinafter referred to as a serration portion 37b1) is provided on the inner circumference of the mounting hole 37b. The mounting hole 37b and the shaft 4a are attached to the opposite side of the holding portion 33, and the rotation direction is determined so as to be fitted in the rotation preventing state, so that the ore teeth portions 37b1, 4al of the both sides are engaged with each other. Further, instead of the serrations 37b1, 4al, a locking portion that can be engaged with a key groove (not shown) and a key groove (not shown) may be used. Further, the rotor 5b is fixed to the shaft 4a with respect to the hub 38 by means of a fixing washer 39' by a fixing member such as a bolt 4'. Thereby, the rotor north can be stably mounted to the shaft 4a. In addition, the assembly sequence for mounting the motor 5 toward the body can have various options. Further, various configurations and methods can be used for the gap positioning portion between the rotation preventing portion and the stator 5a and the outside of the rotor. Further, in the washing machine 5 of the present invention, the rotation axis direction of the drum 4 is inclined at an angle of (four) ± 1 自 from the horizontal direction. Thereby, compared with the washing machine in which the drum 4 is provided in the horizontal direction, it is possible to show that the laundry tends to gather at a low position with respect to the direction of the rotation of the roller. In addition to this tendency, the entanglement and distortion of the clothes can be greatly improved, and the mechanical force can be improved and the wrinkles are less likely to occur. That is, the washing machine 50 of the present embodiment has a drive control for the drum 4 using the control substrate 9 and has a forward-reverse arc-rotation drive mode and a forward-reverse continuous-rotation drive mode. The forward-reverse arc-rotation driving mode is a rotation driving mode in which the arc-rotation and the sharp-reverse rotation are alternately repeated in a condition 5 in which the rotation angle of the drum 4 is greater than 90 degrees and less than 180 degrees. Further, in the forward and reverse arc rotation driving mode, the drum 4 is driven at a rotation speed of about 40 rpm to 60 rpm. Further, the forward-reverse continuous rotation driving mode is to rotate the drum 4 by rotating the speed of the laundry which is lifted by the rotation of the drum 4 from the weight of the laundry itself over the height of the lifting force. The continuous rotation system alternates between the forward and reverse rotation modes. Moreover, the two drive modes can be combined and executed as needed. Figs. 12A to 12F show the driving mode of the drum 4 when the dummy laundry 21 is accommodated in the drum 4. As shown in Fig. 12A, from the stationary state of the drum 4, as shown in Fig. 12B, the drum 4 performs an arcuate rotation of more than 90 degrees and less than 180 degrees. Thereby, the laundry 21 is lifted up to more than 90 degrees and less than 180 degrees. Moreover, by performing the arcuate rotational driving by the reverse of the interaction, the drum 4 can generate a deceleration or braking state due to the reversal of the rotation in the vicinity of the final or final position of the lifting of the laundry 21. Thereby, as shown in Fig. 12C, the laundry 21 can be peeled off from the inner surface of the drum 4 reliably and instantaneously by the forced peeling force generated by the rotational inertia of the garment 21 and the weight of the laundry 21 itself. Then, the operations shown in Figs. 12C to 12F are repeated. That is, as shown in Figs. 12c to 12F, by the interactive forward and reverse arc rotation driving of the drum 4, the lifting position and the falling position of the laundry 21 can be alternately left and right in each orphan driving. 16 1362809 By rotating the drum 4 in such a driving mode, the dispersion of the laundry 21 can be improved. Moreover, the mechanical force can be applied to the laundry 21, and the washing can be performed efficiently. Further, the 12Gth pattern schematically shows a pattern of the forward and reverse arcuate rotation driving modes when the forward and reverse arc rotations of 9 degrees are repeatedly performed. Further, in the positive and negative arc rotation pulsation mode as shown in Figs. 12A to 12F, the entanglement, distortion, wrinkles, and the like of the clothes 21 can be alleviated, but the other side
面，卻不易替換衣物21之上下方向的位置❿易生洗衣斑。 因此，藉㈣駐逆連續旋轉㈣模式，可輕易地實現衣 物21之上下方向的位置的替換。即，藉由正逆娘形旋轉驅 10動模式來減輕衣物21之糾結、扭曲、皴折等，並同時藉由 正逆連續鄕_模式來減輕賦與衣物^之機械力 的不均 衡。如此’藉由併用正逆弧形旋轉驅動模式及正逆連續旋 轉驅動模式兩種模式，在洗衣行程中及洗清行程中，便可 對衣物21進行不同之2個動作。具體而言，藉由正逆弧形旋 15轉驅動模式，可減輕衣物21之糾結、扭曲、皺折等，且可The face is not easy to replace the position of the upper and lower directions of the clothes 21, and it is easy to produce laundry spots. Therefore, the replacement of the position of the upper and lower directions of the clothes 21 can be easily achieved by the (four) counter-rotating continuous rotation (four) mode. That is, the tangling, twisting, folding, and the like of the laundry 21 are alleviated by the positive and negative gyroscopic rotation driving mode, and at the same time, the uneven force of the mechanical force imparted to the laundry is alleviated by the positive and negative continuous 鄕 mode. Thus, by using both the forward and reverse arc rotary drive mode and the forward/reverse continuous rotation drive mode, two different actions can be performed on the laundry 21 during the washing stroke and the washing stroke. Specifically, the tangential, twisted, wrinkled, etc. of the garment 21 can be alleviated by the positive and negative arc rotation 15 rotation driving mode.
實見用手搓洗的動作。又，藉由正逆連續旋轉驅動模式， 使r物21大巾田地連續擺動，可減輕洗衣斑並進行洗務，賦 與均一之洗滌動作。又，因正逆弧形旋轉驅動模式可執行 心弧形旋轉與急逆弧形旋轉交互地反覆進行的動作，故 20加諸於馬達5之驅動負荷大。但是，藉由併用加諸於馬達$ °動負荷比杈小之正逆連續旋轉驅動模式，可減輕加諸 於馬達5之驅動負荷。 口士如上所述，可父互反覆進行滾筒4之弧形旋轉。藉此， ° 乂互正逆進灯將衣物21抬至滾筒4之左右其中一側上部 17 的動作i且’㈣4會在衣物21被抬起之最終地點或最終 地點附近減速或制動。藉此，由於旋轉運動之慣性所生之 之強制剝離力與衣物21本身重量之重力會作驗衣物21， 而玎從滾筒4内面，確實且瞬時地剝離衣物21，並落在滾筒 4之左右相反側。藉由反覆進行該動作，可於每次之狐形旋 轉中左右交替衣物21之抬起位置、落下位置，提高衣物21 之分散作用。因此，可防止衣物21之糾結、扭曲及朝滚筒4 内面貼附，而可輕易地自洗衣機5〇取出衣物幻，並大幅地 緩和附加於衣物21之皺折。又，藉由機械力可及於衣物21， 可將因捶㈣_生之捶洗效果、捶洗清效果及拉平皴折 效果鉍加於衣物21，也大幅地增加衣物21之落下次數。如 此，可有效地提高如洗滌效果等之洗衣機5〇各行程中的機 能。例如，在洗衣行程及洗清行程結束時，衣物21會以糾 結、扭曲、皺折狀態附著於滾筒4内面，在脫水行程結束的 狀態下’衣物21會_地更穩@。但是，藉由在烘乾行程 執行正逆弧形旋轉驅動模式，可左右交替進行衣物21之抬 起位置與落下位置。而且，藉由該動作，伴隨著衣物21間 之左右替換之高分散作用及機械力之作用可作用於衣物 21。又，衣物21可如此地順利散開，並且還可併用正逆連 續旋轉驅動模式。藉此，可進行衣物21之上下替換，提高 各個衣物21的通氣性，供乾之高溫空氣可及於衣物21内部 的各角落。結果，可無斑且在短時間烘乾衣物21。又，伴 隨著在無水狀態下衣物21落下時之捶打作用所生之拉平皺 折作用，可謀求由於散開各個衣物21之扭曲而產生之纖維 1362809 擴張及纖維再生。結果，可大幅地改善洗衣、洗清、脫水、 烘乾後之衣物21的洗後狀態。 又，如第1圖及第5圖所示，轉子5b設有内轉子5bl，且 5玄内轉子5bl具有配設於定子5a内側之磁鐵22、及與磁鐵22 5對應之轉子鐵心23。而且，轉子5b還設有外轉子5b2，且該 外轉子5b2具有配設於定子5a外側之磁鐵22、及與磁鐵22對 應之轉子鐵心23。藉此，轉子5b係相對於1個定子5a，分別See the action of washing by hand. Further, by the forward/reverse continuous rotation driving mode, the r object 21 is continuously oscillated in the large towel field, whereby the laundry spot can be lightened and the washing can be performed, and a uniform washing operation can be imparted. Further, since the forward and reverse arcuate rotation drive mode can perform the operation of the heart-arc rotation and the reverse-revolution rotation alternately, the driving load applied to the motor 5 is large. However, the driving load applied to the motor 5 can be alleviated by using the positive and negative continuous rotation driving mode applied to the motor at a dynamic load ratio of less than 杈. As described above, the sergeant can alternately perform the arcuate rotation of the drum 4. Thereby, the action of raising the laundry 21 to the left and right upper portions 17 of the drum 4 and the '(4) 4 will decelerate or brake near the final or final position where the laundry 21 is lifted. Thereby, the force of the forced peeling force generated by the inertia of the rotational motion and the weight of the weight of the laundry 21 can be used to inspect the laundry 21, and the inner surface of the drum 4 is surely and instantaneously peeled off the laundry 21 and falls on the left and right sides of the drum 4. Opposite side. By repeating this action, the lifting position and the falling position of the laundry 21 can be alternately left and right in each fox-like rotation, and the dispersion of the laundry 21 can be improved. Therefore, the tangling, twisting, and attachment to the inner surface of the drum 4 can be prevented, and the clothing illusion can be easily taken out from the washing machine 5, and the wrinkles attached to the laundry 21 can be greatly alleviated. Further, by the mechanical force, the laundry 21 can be applied to the clothes 21 by the 捶(4)_ raw rinsing effect, the rinsing effect, and the flattening effect, and the number of drops of the clothes 21 can be greatly increased. Thus, the functions of the washing machine 5 such as the washing effect and the like can be effectively improved. For example, at the end of the washing stroke and the washing stroke, the laundry 21 adheres to the inner surface of the drum 4 in an entangled, twisted, and wrinkled state, and the laundry 21 is more stable @ at the end of the dehydrating stroke. However, by performing the forward and reverse arc rotation driving mode in the drying stroke, the lifting position and the falling position of the laundry 21 can be alternately left and right. Further, by this action, the clothes 21 can be acted upon by the action of high dispersion and mechanical force of the left and right replacement between the clothes 21. Further, the clothes 21 can be smoothly spread out in this way, and the forward and reverse continuous rotation drive modes can also be used in combination. Thereby, the upper and lower replacement of the clothes 21 can be performed, and the air permeability of each of the clothes 21 can be improved, and the high-temperature air for drying can be applied to the respective corners of the inside of the clothes 21. As a result, the laundry 21 can be dried without a spot and in a short time. Further, with the flattening wrinkle effect caused by the beating action when the laundry 21 is dropped in the anhydrous state, the fiber 1362809 is expanded and the fiber is regenerated by dispersing the distortion of the respective clothes 21. As a result, the state of washing of the laundry 21 after washing, washing, dehydrating, and drying can be greatly improved. Further, as shown in Figs. 1 and 5, the rotor 5b is provided with an inner rotor 5b1, and the fifth inner rotor 5b1 has a magnet 22 disposed inside the stator 5a and a rotor core 23 corresponding to the magnet 225. Further, the rotor 5b is further provided with an outer rotor 5b2, and the outer rotor 5b2 has a magnet 22 disposed outside the stator 5a and a rotor core 23 corresponding to the magnet 22. Thereby, the rotor 5b is opposed to one stator 5a, respectively
在定子5a之内外周具有轉子鐵心23。因此，在内轉子5Μ與 外轉子5b2之間有電磁作用作用於定子允。所以，可使馬達 1〇 5之馬達轉矩增大而不妨礙到馬達5之振動、噪音的減低。 又，可活用定子5a内周側與軸承部24之間的死空間，形成 内轉子5bl。如此，藉由轉子5b具有内轉子5Μ及外轉子 加’馬達5可紋地執行如正逆弧形旋轉驅域式般劇烈 且驅動負荷高之驅動。A rotor core 23 is provided on the outer circumference of the stator 5a. Therefore, an electromagnetic action acts between the inner rotor 5 and the outer rotor 5b2 on the stator. Therefore, the motor torque of the motor 1 〇 5 can be increased without hindering the vibration of the motor 5 and the noise reduction.

In this way, even when the motor 5 that raises the torque performs the forward-reverse arcuate rotation drive mode, if the deviation occurs at the reverse position, the reliability of the motor 5 such as the torque reduction, the speed fluctuation, and the early dance life is lowered. The situation. For example, the torque reduction and the speed variation are due to the deterioration of the controllability of the motor 5. The lowering of the life is due to a significant drop such as vibration or auxiliary support 24. In order to cope with the problem that the reliability of the motor 5 is lowered, the motor 5 has a rotational position (four) (10) (hereinafter referred to as a detecting portion 26). That is, the detecting unit 26 can detect the position of the secret (4). Motor 5: 19 1362809 The position is the rotational position of the rotor 5b. The detecting unit 26 has three sensors 26a and a sensor housing 26b. The three sensors 26a correspond to the u phase, the v phase, and the w phase of the three-phase alternating current, respectively. Further, the sensor 26a is provided on the end surface 26c' of the sensor housing 26b on the stator 5a side, and the detecting surface is directed in the direction of the shaft 4a, that is, on the rotor 55b side. Further, among the plurality of mounting portions 32, the adjacent two mounting portions 32 are respectively provided with a connecting surface 5c for providing the sensor housing 26b. The connecting surface 5c is attached to the mounting portion 32 provided with the connecting surface 5c. form. Further, the detecting portion 26 is provided with mounting holes 26d on both sides in the circumferential direction of the sensor case 26b, and screw holes 32b are provided in the connecting surface 5c. When the detecting portion 26 is attached to the stator 5a, the sensor housing 26b is placed on the joint surface, and the screw 45 is passed through the mounting hole 26d from the opposite side of the mounting portion 32 to be screwed. The screw hole 32b is fixed to the screw hole 32b. Thereby, the sensor body 26b and the mounting portion 32 can be fixed together. As a result, the detecting portion % can be stably attached to the stator 5a. Since the low speed and large torque are required, the motor 5 for the direct drive mode of the washing machine 50 or the like can be used in many cases. At this time, for example, when the number of poles of the motor 5 is 2P, the mechanical angle of 36 就 is equivalent to an electrical angle of (36 〇χΡ). Therefore, the mechanical position detection error of the detecting portion 26 is electrically increased by a factor of two. The large electrical error causes deterioration of the controllability of the motor 5 when the motor 5 is controlled. Under the same controllability determination, the more the number of poles of the motor 5 is, the more it is necessary to reduce the mechanical position detection error of the detecting portion 26. For example, when the motor 5 is a 30-pole motor (ρ = 15), the electrical angle 36 is equivalent to a mechanical angle of 24 degrees (= 360 / 15). Namely, the mechanical position detection error of the detecting portion 26 is electrically increased by 15 times. On the other hand, the three sensors 26a normally generate signals in electrical cycles corresponding to the three-phase coils 542U, v 20 phases, and W wound around the stator core 20, respectively. Thereby, it is possible to switch the timing at which the electric power is respectively applied to the three-phase coil phase, the 乂 phase, and the w phase. For this reason, for example, it is conceivable to configure the sensor 26a as a structure disposed at a mechanical position of an electrical angle of 10 degrees (10) or a mechanical position of (4) electrical insulation. Further, in the configuration of the arbitrarily-sensor 26a, the aforementioned position detection error is increased by P times. In this case, the motor 5 having the number of poles is taken as an example. The detection unit 26 deviates from the electrical angle by 15 degrees as long as the mechanical angle deviates by 1 degree, and becomes a maximum deviation amount. Further, when the number of poles of the motor 5 is 2p, the magnetic flux The chain is 03, the motor current is the difference between the induced voltage of the la' phase and the motor current, that is, the advance angle is p, the fine inductance is Lq, the d pumping inductance is (10), and the motor torque τ can be expressed by the following formula (1): T= P(^a-Iacosp-f〇.5·(Lq-Ld) ·Ια2·δίη(2·β)) (1) Further, the deviation of the electrical angle is expressed as the deviation of β. When the motor 5 is controlled by torque control or revolution control, if there is a large deviation of β from 丨5 degrees, the motor torque value to be controlled will be greatly deviated, and the controllability will be greatly deteriorated. (1) Imagine. Therefore, the high-precision positioning mounting detecting portion 26 is extremely important. # '', for example, can sufficiently obtain the predetermined degree of control, and the maximum deviation amount of β is about ±5 degrees. Further, the maximum deviation amount of P can be controlled to about ±5 degrees. The detection error of the rotational position can be reduced to a state where the accuracy is relatively high. In the motor 5 of the present embodiment, the stator 5 has the first positioning portion 41 and the second positioning portion 42, and the detecting portion 26 has the first portion 43 and the second fitting portion 44. Thereby, when the stator 5a and the detecting portion % are assembled, as shown by the imaginary lines in Figs. 8A to 9B, the second positioning portion 41 is embedded with the first and the 443. The second positioning portion 42 is fitted to the second fitting portion 44. As shown in Fig. 1B, the first positioning portion 41 has a convex shape on the side of the casing 26b in the axial direction of the shaft 4a. Further, the i-th positioning portion 41 is provided at two places on the joint surface 5C. Further, as shown in the figure, the second positioning portion 42 is provided on the outer peripheral surface 5d of the stator 5a, and has a shape in which the shaft is oriented in the radial direction toward the side of the sensor housing 26b. In other words, the second positioning unit 42 is provided in two places. Further, the first fitting portion 43 is not disposed in the mounting hole 26, and can be fitted to the first positioning portion 41 in the direction of the shaft 4a, and has a direction toward the shaft. The shape of the hole in the axial direction. Further, as shown in FIG. 1A, the second fitting portion 44 is provided on the end surface 26c, and has a diameter that can be fitted to the second positioning portion 42 in the radial direction of the shaft 4a and toward the shaft 4a. The concave shape of the direction. Further, as shown in Fig. 10A, the first fitting portion 43 has a hole shape in the axial direction of the shaft 4a. Further, the first fitting portion 43 may have a concave shape that is fitted to the first positioning portion 41 in the axial direction. In addition, the second positioning portion 42 and the second fitting portion 15 44 are provided in two places, but they are not limited to two, and may be one or more. Further, as shown in FIG. 10D, the first positioning portion 41 may have a hole shape in the axial direction of the shaft 4a. Further, as shown in the figure, the second positioning portion 42 may have a concave shape in the radial direction of the shaft 4a. At this time, as shown in FIG. 10C, the first fitting portion 43 has a convex portion that can be fitted to the first positioning portion 41 in the axial direction of the shaft 4a and that is attached to the mounting portion 32 side in the axial direction of the shaft 4a. Shaped shape. Further, as shown in Fig. 10C, the second fitting portion 44 has a shape that can be fitted to the second positioning portion 42 in the radial direction of the shaft 4a and has a convex shape in the radial direction of the shaft 4a. Further, as shown in Fig. 10D, the first positioning portion 41 has a hole shape of 22 1362809 in the axial direction of the shaft 4a. Further, the second positioning portion 4i may have a concave shape that can be fitted to the first fitting portion 43 in the axial direction. As shown in Fig. 10B and Fig. 〇d, the second positioning portion 41 and the second positioning portion 42 are provided in the molding portion 31 by integral molding or the like. Thereby, the position in the radial direction, the position in the circumferential direction, and the position in the axial direction have a positional relationship in a sense with respect to the teeth 20a for constituting the stator 5a. Therefore, when the first fitting portion 43 and the first clamping portion 41 are fitted in the axial direction, the detected portion % is displaced by the position in the outer circumferential direction and the outer circumference of the tooth 2〇a. The concentricity of the face is limited by the position after substantial restriction. Further, when the second engaging portion 44 and the second fixed ten-position portion 42 are fitted in the radial direction, the detecting portion % is displaced from the position in the inner circumferential direction and in the circumferential direction with respect to the tooth 20a. The positional limit after the relationship is substantially restricted. As a result, the positioning accuracy of the detecting portion 26 can be improved with respect to the predetermined number of teeth 2〇a. 15 20 The round Han brother "%..., the music position 41 is located at the same position as the first positioning unit 41! The fitting portion 43 has the same positional relationship. Similarly, the second positioning portion 42 is located in the same positional relationship as the second moving material that can be called by the second positioning portion. Thereby, the axial direction of the first fitting operation by the first positioning portion i and the first fitting portion 43 and the second fitting operation of the second positioning portion 42 and the second fitting portion 44 can be simultaneously performed. The fitting and the radial direction::=, by preferentially performing at least the - fitting operation, the fitting condition can be reduced to + to start the middle-fitting action. Thereby, the initial fitting state of the operation causes the detecting portion 26 to be located near the ', ~ port position or the aligned position. Moreover, with the action team σ and the same as i - the fitting action, the door is easy to start another - fitting action. Moreover, the detecting portion 26 can be positioned relative to the stator 5a by the two fitting operations, 23 jW8〇9 10 15 20 . As shown in Fig. 11, the detecting portion 26 is positioned in the state where the detecting portion 26 is held at the positioning position, and the detecting portion 26 is screwed and fixed to the stator 5a by the screw 45. As a result, the detecting portion 26 and the stator 5a can be fixed together without positional deviation. In addition, as shown in FIG. 9B, the i-th fitting amount L1 in the axial direction of the first positioning portion 41 and the second fitting portion 43 is compared with the axial direction of the second positioning portion 42 and the second fitting portion 44. The second embedded amount 匕2 is the relationship of LI < L2. In addition, the first chirp amount L1 is the first! The length of the fixed portion 41 and the first fitting portion 43 in the axial direction is the length of the second fitting portion L2 in the axial direction in which the second positioning portion 42 and the second fitting portion 44 are fitted. Therefore, when the fixing operation of the detecting unit 26 and the stator 5a is performed, first, the second positioning unit 42 and the second fitting unit 44 are started, and then the first positioning unit 41 and the i-th cutting are opened. The (10) operation of the joint 43 is combined. Thereby, the fitting operation can reduce the fitting condition by half and simultaneously start the fitting operation, and the first fitting operation operates in parallel with the second fitting operation. :, _ _ 2nd check = real;: Γ 齿 齿 齿 齿 齿 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位 定位Zhou Fang system. As a result, the accuracy of the position PP after the relationship is substantially restricted. For the predetermined number of teeth, the detection unit can be adjusted, and the first unit 41 can be fitted to the first positioning unit. The first fitting portion 24 of the first fitting portion 42 corresponds to the second fitting portion 44 that can be fitted to the second positioning portion 42. The fitting operation is preferentially performed at least. One fitting operation is easily started in a state in which the fitting condition is halved. Further, from the initial fitting operation, the detecting portion 26 can be placed near the fitting position of the other fitting motion 5 or After the fitting position, the fitting of one of the fitting operations can be performed, and the fitting of the other fitting operation can be easily started. Further, the two folding operations can be continued to end the pulling operation, thereby enabling high-precision positioning. The tooth 20a and the detecting portion 26. Therefore, the fixing operation of the stator 5a and the detecting portion 26 can be realized in a simple and short time without any difference. 10 As shown in Fig. 10B and Fig. 1D, the third positioning is performed. The portion 41 and the second positioning portion 42 are provided in the mold portion 31 by body molding or the like. In the teeth 20a constituting the stator 5a, the radial direction position, the circumferential direction position, and the axial direction position may have a positional relationship. Therefore, the second engagement portion 43 and the first positioning portion 41 are in the axial direction. When the fitting portion 26 is engaged, the position of the outer peripheral portion 15 is deviated and the concentricity with respect to the arcuate surface of the outermost circumference of the tooth 20a is substantially restricted. Further, the second fitting portion 44 is restrained by the second fitting portion 44. When the second positioning portion 42 is fitted in the radial direction, the detecting portion 26 is restricted by the positional deviation in the inner circumferential direction and the positional relationship with respect to the circumferential direction of the tooth 20 a. With respect to the predetermined number of teeth 2〇a, the positioning accuracy of the detecting portion 20 can be improved. Further, after being positioned relative to the detecting portion 26 of the stator 5a, the state in which the direction of the stator 5a is maintained can be fixed by screws. The detection portion % is easily attached to the stator 5a to maintain the positioning state, and the direction of the stator & for example, the posture of the joint surface 5c is upward. Therefore, the positioning accuracy of the detection portion 26 of 25 1362809 can be ensured. The detection unit 26 can be simple It is attached to the stator 5a in a short time. As shown in Fig. 8A to Fig. 9B, the fitting of the first positioning portion 41 and the second positioning portion 42 in the axial direction and the fitting in the radial direction are performed at the same time, for example, The relationship between the fixed portion 5 and the detecting portion 26 may be a relationship between the detecting portion 26 and the second fitting portion 44 in the axial direction as long as it is the second positioning portion 42 in the radial direction. This relationship can also be mutually fitted in the axial direction and

However, in the present embodiment, the first positioning portion 41 and the first fitting portion 43 are in the axial direction! The fitting 10 sL1 ' is smaller than the second fitting L2 in the axial direction of the second positioning portion 42 and the second fitting portion 44. In other words, the amount of protrusion from the first positioning portion 41 for receiving the joint surface 5c of the installation surface of the detecting portion 26 is made small. Further, the dog output amount of the second positioning portion 41 is equal to the first fitting amount L1. Thereby, the installation surface 26e of the detecting portion 26 can be slid on the first positioning portion 41, and the second fitting portion 44 can be fitted in the direction from the second fixed portion 42.

In the time when the enemy cooperation industry in which the second positioning portion 42 is fitted in the radial direction is completed, the 'i-fitting portion 43 can be both in the financial direction and the financial direction with respect to the first bowl portion. On the opposite position. In the case of bribery, the inclination of the detecting portion 26 with respect to the joint surface 5e can be suppressed to a small range to be 443 relative to the first! The positioning department needs to be reversed to be able to locate the game. Further, it is possible to == the clearance of the fitting of the first fitting portion 43 and the first positioning portion 41. Therefore, the positioning accuracy in the direction of the diameter 26 of the fixing and detecting (4) can be improved. The fitting of the second positioning portion 42 and the second fitting portion 44 can be performed separately. Therefore, even if there is no play (gap) in the circumferential direction, the fitting can be easily performed with respect to the teeth 2 arranged in the circumferential direction. 〇a, the positional restriction in the circumferential direction of the most important sensor 26a can be positioned with high precision, whereby the rotational position detection accuracy of the rotor 51 can be further improved. As described above, the 'fitting of the second positioning portion 42 and the second fitting portion 44 in the radial direction' is detected in the positioning order in which the fitting of the first positioning portion 41 and the first fitting portion 43 in the axial direction is preferentially performed. The portion 26 is formed in a posture in which the teeth 20a are aligned with the plane and the joint 5c is kept parallel. Further, the detecting unit 26 slides on the joint surface 5c in an inclined posture, and the second fitting portion 44 is fitted to the second positioning portion 42, and then the first fitting portion 43 is slid into the first positioning portion 41. Just fine. In this manner, even if the detecting portion 26 is tilted with respect to the joint surface 5C, and the detecting portion 26 is assembled to the stator 5a', the first positioning portion 41 and the second engaging portion 43 can be easily fitted. Further, as shown in Fig. 11, the attachment portion 32 is formed at a position where the stator 5a extends further outward than the rotor 5b, and the joint is formed on the attachment portion 32. Further, the joint portion 5c is formed with a detecting portion 26. Further, as shown in Fig. 11, in the positional relationship in which the joint of the stator 5a is covered with the rotor %, the joint allows the gap 45 to be formed between the rotor 5b. The detecting portion 26 can be positioned and mounted by inserting the joint surface 5c from the side of the stator 5a and the north of the rotor through the gap. Further, when the inspection unit 26 needs to perform maintenance or the like, the attachment and positioning of the detection unit % can be released, and the detection unit 26 can be easily detached. Therefore, when the detecting portion 26 is attached or detached, the rotor 5b does not interfere with the work, and the loading and unloading operation of the detecting portion 26 can be easily performed. Further, as shown in Figs. 8A and 8B, the installation surface 26e attached to the position substantially perpendicular to the second positioning portion 41 is not sealed with the stator 5a as shown in Figs. 9A and 9]. The joint 5c which is almost perpendicular to the axial direction abuts and is IU set as shown in Fig. 6 and Fig. 11_. Thereby, the position of the detecting portion 26 in the axial direction can be accurately determined. Further, as shown in Fig. 6, Fig. 9A, Fig. 9B, and Fig. ,, the joint faces are provided on the opposite side of the stator of the stator 5a toward the direction of the body 1 of the body. As described above, when the detecting portion 26 is in the axial direction by the first positioning portion 41 and the first fitting portion S, the installation surface 26e can be positioned in the axial direction at the abutting contact surface 5c. Further, the installation surface 26e is formed as a substantially right-angled surface with respect to the first positioning portion 41, and the joint surface 5c is formed to be substantially perpendicular to the surface in the axial direction, and the detecting portion 26 is subjected to the plurality of circumferential direction-arranged teeth 2 The restriction of the position of the 〇a and the rotor % in the axial direction and the inclination with respect to the plane of the arrangement of the teeth are coordinated with the first positioning portion 41 or individually. Thereby, the positional accuracy of the detecting unit 26 when attached to the stator 5a can be improved. X, the joint 5c is set on the opposite side of the orientation of the body to the body of the body 1. Moreover, the joint & is formed with the mounting body. Thereby, the mounting state of the detecting portion 26 toward the outside can be obtained. Therefore, the loading and unloading at the time of maintenance of the detecting unit 26 is advantageous for the exchange operation. (4) When the washing machine 5Q is provided with the drum 4 arranged horizontally or obliquely, the back surface of the water tank 2 to which the motor 5 is mounted with respect to the main body is located on the inner side of the rear surface of the main body 1. Therefore, as shown in Fig. 2, after the panel (10) of the shirt disassembling main body 11 is unsent, the handling unit 26 is simply attached and unloaded. 〇The possibility of industrial use is used. X month can be used for detecting the rotational position of a rotor that can constitute a motor. The -2 is mounted, and the rotational position detecting portion can be easily and accurately positioned with respect to the motor to obtain high position detection accuracy.
