Description
本發明係有關一種磁阻馬達，其包括轉子及定子，定子構成外露的定子極，其上設有繞組，定子與繞組之間設有繞組載體，而且/或者，定子被容置在定子殼內。The invention relates to a reluctance motor comprising a rotor and a stator, the stator forming an exposed stator pole, a winding is arranged thereon, a winding carrier is arranged between the stator and the winding, and/or the stator is housed in the stator shell .
上述之磁阻馬達為習知。例如，參閱DE 103 37 916 A1。其提出一種磁阻馬達，可降低馬達運作時產生音聲的磁阻馬達具有構成繞組載體的定子蓋，其係套設在外露的定子極上而構成定子繞組之載體。此外，上述將磁阻馬達設在定子殼中亦為習知，定子殼尤其具有包圍定子的壁、及設在定子端面以軸設轉子轉軸的橋部。The above reluctance motor is conventional. See, for example, DE 103 37 916 A1. It proposes a reluctance motor, which can reduce the reluctance motor that generates sound when the motor is operated, and has a stator cover constituting a winding carrier, which is sleeved on the exposed stator pole to form a carrier of the stator winding. Further, it is also known to provide the reluctance motor in the stator case. The stator case has, in particular, a wall surrounding the stator, and a bridge portion provided on the end face of the stator to axially connect the rotor shaft.
高電磁力使得定子中激發出振盪。馬達通電後，定子及繞組中會產生微小震動，例如，鐵的電伸縮、繞組銅線間的力、及轉子與定子間的電磁交互作用。該力作用之頻率受馬達轉速所左右。視頻率之不同，可在系統中激發出共振，故，使得高速旋轉的馬達出現共振效應。High electromagnetic forces cause oscillations to be excited in the stator. When the motor is energized, small vibrations are generated in the stator and the winding, for example, the electrical expansion and contraction of iron, the force between the winding copper wires, and the electromagnetic interaction between the rotor and the stator. The frequency of this force is affected by the motor speed. The difference in video rate can excite resonance in the system, so that the motor rotating at high speed has a resonance effect.
本發明之目的在於提供一種上述之磁阻馬達，其可進一步改良磁阻馬達轉速範圍內的共振效應。It is an object of the present invention to provide a reluctance motor as described above which further improves the resonance effect in the range of the reciprocating motor speed.
本目的由申請專利範圍第1項之標的物達成，其中，繞組載體及/或定子殼部分與定子有一段距離。故，防止諸如繞組載體及/或定子殼之類的部分之共振振盪產生的動作，例如，碰撞定子，以避免產生令人不適的噪音。由於繞組載體及/或定子殼係部分地與定子有一段距離，所以，使得共振發生在馬達轉速範圍之外。故，避免了繞組載體及/或定子殼與定子全面式接觸。This object is achieved by the subject matter of claim 1 in which the winding carrier and/or the stator casing portion are at a distance from the stator. Therefore, actions caused by resonance oscillations of portions such as the winding carrier and/or the stator casing are prevented, for example, from striking the stator to avoid generation of uncomfortable noise. Since the winding carrier and/or the stator housing are partially at a distance from the stator, resonance occurs outside of the motor speed range. Therefore, the winding carrier and/or the stator shell are prevented from being in full contact with the stator.
其他特徵主要依據申請專利範圍第1項之標的物或其他申請專利範圍之特徵。其亦可只依據申請專利範圍第1項或其他申請專利範圍之單項特徵或為獨立。Other features are mainly based on the subject matter of claim 1 or the scope of other patent applications. It may also be independent of the individual features of claim 1 or other patent applications.
在一較佳實施例中，繞組載體及/或定子殼設有凸起，而部分與定子有一段距離。在另一實施例中，定子設有凸起，而部分與繞組載體及/或定子殼有一段距離。穿過定子的轉子轉軸之凸起或凹口使其抵靠部分產生一段距離。此處較佳的是，使繞組載體及/或定子殼與定子之間的接觸為非全面式的接觸，尤其是，點狀或線狀接觸。In a preferred embodiment, the winding carrier and/or the stator housing are provided with projections and a portion at a distance from the stator. In another embodiment, the stator is provided with a projection and a portion is at a distance from the winding carrier and/or the stator housing. The projections or recesses of the rotor shaft passing through the stator cause a distance to the abutment portion. It is preferred here that the contact between the winding carrier and/or the stator housing and the stator is a non-common contact, in particular a point or line contact.
在另一較佳實施例中，凸起延伸在轉子軸向上，亦即，平行於轉子轉軸或至少大致平行，亦即，構成一個0.5°至30°的銳角。此處，凸起可設作成凸肋，而達到線狀接觸。凸肋突出於相鄰的繞組載體及/或定子之殼壁，設在定子上時，則突出於定子。In a further preferred embodiment, the projections extend in the axial direction of the rotor, i.e. parallel to the rotor shaft or at least substantially parallel, i.e. form an acute angle of 0.5 to 30. Here, the projections can be formed as ribs to achieve linear contact. The ribs protrude from the adjacent winding carrier and/or the shell wall of the stator, and when placed on the stator, protrude from the stator.
為避免磁阻馬達轉速範圍內的共振效應，可使相對於定子有一段距離的部分佔截面圓周線的20%至98%。因此，繞組載體及/或定子殼抵靠在定子上的部分只佔圓周線約2%至80%，尤其是2%至10%；如包圍定子的定子殼之周長為250mm時，則抵靠部只約為10mm至15mm，而該抵靠部由較佳設作成凸肋的凸起所構成，其均勻或不規則地分佈在圓周上。圓周方向上產生多個小支撐面，而達到點狀或線狀接觸。故，使繞組載體及/或定子殼上的凸起在圓周方向上的延伸長度，等於或小於繞組載體及/或定子殼壁厚；繞組載體及/或定子殼之壁厚為1mm至5mm時，凸起在圓周方向上的延伸長度為5mm或以下。進一步，使凸起在圓周方向上的延伸長度為繞組載體及/或定子殼之壁厚的十分之一至一半，故，壁厚為1mm至5mm時，凸起在圓周方向上的延伸長度為0.1mm至2.5mm，此處尤其是設在繞組載體上的凸起及繞組載體壁厚。To avoid resonance effects in the range of reluctance motor speeds, the portion that is at a distance from the stator can be 20% to 98% of the circumference of the section. Therefore, the portion of the winding carrier and/or the stator shell that abuts against the stator only occupies about 2% to 80% of the circumferential line, especially 2% to 10%; if the circumference of the stator casing surrounding the stator is 250 mm, The abutment is only about 10 mm to 15 mm, and the abutment is constituted by projections which are preferably provided as ribs which are uniformly or irregularly distributed on the circumference. A plurality of small support faces are produced in the circumferential direction to achieve point or line contact. Therefore, the length of the protrusions on the winding carrier and/or the stator shell in the circumferential direction is equal to or smaller than the thickness of the winding carrier and/or the stator shell; when the wall thickness of the winding carrier and/or the stator shell is 1 mm to 5 mm The protrusion has an extension length of 5 mm or less in the circumferential direction. Further, the extension length of the protrusion in the circumferential direction is one tenth to one half of the wall thickness of the winding carrier and/or the stator case, so the extension length of the protrusion in the circumferential direction when the wall thickness is 1 mm to 5 mm In the case of 0.1 mm to 2.5 mm, in particular, the projections on the winding carrier and the winding carrier wall thickness.
在另一實施例中，繞組載體及/或定子殼上的凸起在圓周方向上的延伸長度，等於或大於繞組載體及/或定子殼之壁厚，故，為上述壁厚時，凸起在圓周方向上的延伸長度為5mm或以上。此處較佳的是，使凸起在圓周方向上的延伸長度為繞組載體及/或定子殼之壁厚的1.5至10倍。故，為上述壁厚時，凸起在圓周方向上的延伸長度為1.5mm至50mm。此處尤其是設在定子殼上的凸起及定子殼壁厚。In another embodiment, the length of the protrusions on the winding carrier and/or the stator case in the circumferential direction is equal to or greater than the wall thickness of the winding carrier and/or the stator case, so that the wall thickness is the protrusion. The length in the circumferential direction is 5 mm or more. Preferably, the length of the projection in the circumferential direction is 1.5 to 10 times the wall thickness of the winding carrier and/or the stator housing. Therefore, in the case of the above wall thickness, the projection has a length in the circumferential direction of 1.5 mm to 50 mm. In this case, in particular, the projections on the stator housing and the stator shell wall thickness.
定子殼較佳由金屬板件所構成，尤其是彎曲或衝壓板件，而定子殼係由兩部分構成，構成距離的部分設在具有上方橋部的殼體部上。在另一實施例中，構成距離的部分亦設在具有下方橋部的殼體部上，而此橋部係用於將定子殼固定於定子，尤其是夾緊固定。定子殼夾緊固定於定子上時，包圍定子的殼體部分與定子構成一段距離，對上述之共振效應為有利，此處，構成距離的凸起較佳成形在定子上。定子由形狀相同的定子板上下堆疊而成時，與定子殼構成一段距離的凸起則較佳以衝壓成形在定子板之外輪廓上。The stator casing is preferably formed of a metal plate member, in particular a bent or stamped plate member, and the stator casing is composed of two parts, and the portion constituting the distance is provided on the casing portion having the upper bridge portion. In another embodiment, the portion constituting the distance is also provided on the housing portion having the lower bridge portion for securing the stator housing to the stator, in particular clamping. When the stator casing is clamped and fixed to the stator, the housing portion surrounding the stator forms a distance from the stator, which is advantageous for the above-mentioned resonance effect. Here, the projections constituting the distance are preferably formed on the stator. When the stator is stacked on the upper and lower sides of the stator of the same shape, the projections which form a distance from the stator casing are preferably formed by stamping on the outer contour of the stator plate.
繞組載體較佳由電絕緣塑膠射出成形件構成，其承載定子繞組，並構成定子絕緣體。The winding carrier preferably consists of an electrically insulating plastic injection molded part that carries the stator windings and constitutes a stator insulator.
可選擇非接觸面之間的距離，使得，即使在極度條件下，該等面亦不會出現接觸，亦即，凸起之間的面由於振盪而彎曲時，或相對於轉子轉軸之徑向而彎曲。此處，兩個抵靠部分之間的周長為凸起在圓周方向延伸長度的一至五十倍，故，凸起在圓周方向延伸長度為1mm至5mm時，兩個抵靠部分之間的非抵靠部分之周長例如為1mm至50mm。The distance between the non-contact faces can be selected such that even under extreme conditions, the faces are not in contact, that is, when the faces between the protrusions are bent due to oscillation, or the radial direction with respect to the rotor shaft And bent. Here, the circumference between the two abutting portions is one to fifty times the length of the protrusion extending in the circumferential direction. Therefore, when the protrusion extends in the circumferential direction by a length of 1 mm to 5 mm, between the two abutting portions The circumference of the non-abutting portion is, for example, 1 mm to 50 mm.
上述寬度範圍包括所有中間值，尤其是其下及/或上界限值十分之一的部分。「及」在此處係指兩界限值可再各推移十分之一的部分。The above range of widths includes all intermediate values, especially the portion of the lower and/or upper limit values. "And" here means the part of the two threshold values that can be shifted by one tenth.
以下將依據附圖詳細說明本發明之實施例。Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
圖1顯示一個磁阻馬達，其為一個4/2磁阻馬達1。該二相馬達設有一個固定在轉子轉軸2上的轉子3。該轉子具有兩個在直徑上相對的轉子極4。磁阻馬達1運轉時，轉子3使對一條穿過轉軸2的幾何轉軸線x旋轉。Figure 1 shows a reluctance motor which is a 4/2 reluctance motor 1. The two-phase motor is provided with a rotor 3 fixed to the rotor shaft 2. The rotor has two diametrically opposed rotor poles 4. When the reluctance motor 1 is in operation, the rotor 3 rotates against a geometrical axis x passing through the shaft 2.
包圍轉子3的定子5具有四個位在轉子3圓周方向上而彼此互為90°角的定子極6，其承載著構成線圈的定子繞組7。The stator 5 surrounding the rotor 3 has four stator poles 6 positioned in the circumferential direction of the rotor 3 at an angle of 90° to each other, which carries the stator windings 7 constituting the coils.
為使繞組7對定子5電絕緣，定子極6與定子極6之間圓周方向上的諸定子壁8皆被一塑膠射出成形件構成的繞組載體9所覆蓋。如圖3所示，繞組載體之截面為盆狀，以覆蓋住定子之鄰接繞組的部分。In order to electrically insulate the stator 7 from the stator 5, the stator walls 8 in the circumferential direction between the stator pole 6 and the stator pole 6 are covered by a winding carrier 9 formed of a plastic injection molded part. As shown in Figure 3, the winding carrier has a basin shape to cover the portion of the stator adjacent to the winding.
定子5被容置在包覆定子的定子殼10中，如圖所示，其具有覆蓋定子5之頂側的橋部11。定子5之相對於橋部11的一側，同樣設有結構近似而未示出的橋部。The stator 5 is housed in a stator casing 10 encasing the stator, as shown, having a bridge portion 11 covering the top side of the stator 5. The side of the stator 5 with respect to the bridge portion 11 is also provided with a bridge portion which is similar in structure and not shown.
橋部11作用在於軸設轉子轉軸2，故，橋部11具有一個中心容置孔12。該容置孔可用於容置諸如滾珠軸承，以軸設轉子轉軸。The bridge portion 11 functions to axially set the rotor shaft 2, so that the bridge portion 11 has a center receiving hole 12. The accommodating hole can be used for accommodating, for example, a ball bearing to axially set the rotor shaft.
橋部11並具有邊框13，其係圍繞著轉軸線x。該邊框包圍定子5之端部，並部分地抵靠其外側面。The bridge portion 11 also has a bezel 13 which surrounds the axis of rotation x. The frame surrounds the end of the stator 5 and partially abuts against its outer side.
定子5由一疊相同的定子板14所構成，其係以衝壓成形。所組成的定子5之壁外側具有四個互相構成90°角的定子外側面15，其各配合一個徑向向內延伸的定子極6。定子外側面15在定子5之圓周方向上的角被削圓，其係以轉軸線x為中心而各具有一半徑。The stator 5 is formed by a stack of identical stator plates 14, which are formed by stamping. The outer side of the wall of the stator 5 is formed with four stator outer sides 15 which form an angle of 90[deg.], each of which cooperates with a radially inwardly extending stator pole 6. The corners of the stator outer side surface 15 in the circumferential direction of the stator 5 are rounded, each having a radius centered on the rotation axis x.
如圖4之定子5之截面放大圖所示，定子外側面15設有凸起及凹口，故構成一個與橋部邊框13不連續的抵靠面。凸起16相對於轉軸線x具有徑向高度a，其約為橋部11之邊框13之材料厚度的0.5倍。該凸起16之橫向(亦即，在圓周方向上)的寬度b約為高度a之10倍。As shown in the enlarged cross-sectional view of the stator 5 of Fig. 4, the outer side surface 15 of the stator is provided with projections and recesses, so that an abutting surface which is discontinuous with the bridge frame 13 is formed. The projection 16 has a radial height a with respect to the axis of rotation x which is approximately 0.5 times the material thickness of the bezel 13 of the bridge 11. The width b of the projection 16 in the lateral direction (i.e., in the circumferential direction) is about 10 times the height a.
每一個定子外側面15上設有三個在圓周方向上均勻分佈的凸起16，而相鄰兩凸起16之距離約等於凸起寬度b。Each of the stator outer side faces 15 is provided with three projections 16 uniformly distributed in the circumferential direction, and the distance between the adjacent two projections 16 is approximately equal to the projection width b.
本實施例中每一個凸起16在圓周方向上的延伸長度，即，凸起寬度b，加上兩倍的高度a，約等於邊框13之材料厚度的10倍。每一個凸起16平行於轉軸線x而延伸在整個定子外側面15上，亦即，由橋部11至相對的另一端。The extension length of each of the projections 16 in the circumferential direction in this embodiment, that is, the projection width b, plus twice the height a, is approximately equal to 10 times the thickness of the material of the bezel 13. Each of the projections 16 extends parallel to the axis of rotation x over the entire outer side 15 of the stator, that is, from the bridge portion 11 to the opposite end.
由於上述之凸起16，定子殼10之邊框13與定子部分有一段距離，而該距離係由凸起高度a所定義。諸定子5之削圓的邊角亦存有一段距離，故，削圓的邊角處的邊框與定子5有一段距離。Due to the projections 16 described above, the bezel 13 of the stator casing 10 is at a distance from the stator portion, and the distance is defined by the projection height a. The corners of the rounded corners of the stators 5 also have a distance, so that the frame at the rounded corners is at a distance from the stator 5.
因此，對定子殼10只存在線狀的接觸，尤其是，邊框13與定子5。利用凸起16選擇彼此之距離，可使馬達1轉速範圍內無共振。此外，不互相接觸的彼此相面對的距離，可利用凸起高度a而選擇，使得，振盪時邊框13之凸起16之間的部分出現的彎曲變形，不會造成對定子的接觸，尤其是，橋部11迫緊接合在定子5上。Therefore, there is only a linear contact to the stator case 10, in particular, the bezel 13 and the stator 5. By using the projections 16 to select the distances from each other, there is no resonance in the rotational speed range of the motor 1. In addition, the distances that are not in contact with each other can be selected by using the height a of the protrusions, so that the bending deformation of the portion between the protrusions 16 of the frame 13 during the oscillation does not cause contact with the stator, especially Yes, the bridge portion 11 is forcedly engaged on the stator 5.
繞組載體9亦非整面抵靠在定子5之相對的壁或定子極6上。繞組載體9係以其壁外側上平行於轉軸線x的凸起17，抵靠定子5之相對的壁，其係由凸肋所構成。該凸起與繞組載體9為一體成形，呈凸肋狀而與繞組載體9相對的定子壁線狀接觸。The winding carrier 9 also has no entire surface against the opposite wall or stator pole 6 of the stator 5. The winding carrier 9 is abutment against the opposite wall of the stator 5 with projections 17 on the outside of the wall parallel to the axis of rotation x, which are formed by ribs. The projection is integrally formed with the winding carrier 9, and has a rib shape and is in linear contact with the stator wall opposite to the winding carrier 9.
如圖5所示，肋狀凸起17之截面為圓弧形，凸起17之連接繞組載體壁18的根部在圓周方向上具有寬度c，其約為壁18之厚度的三分之一。垂直於凸起寬度c的高度d約為凸起寬度c的一半，故，凸起17在圓周方向上的延伸長度約為壁18之厚度的一半。As shown in Fig. 5, the rib-like projection 17 has a circular arc shape, and the root portion of the projection 17 connecting the winding carrier wall 18 has a width c in the circumferential direction which is about one third of the thickness of the wall 18. The height d perpendicular to the width c of the projection is about half of the width c of the projection, so that the length of the projection 17 in the circumferential direction is about half the thickness of the wall 18.
諸凸起17在繞組載體壁18之圓周方向上彼此有一段距離，在所示實施例中，兩相鄰凸起17之距離約為凸起17在圓周方向上延伸長度的10倍。The projections 17 are at a distance from each other in the circumferential direction of the winding carrier wall 18. In the illustrated embodiment, the distance between the two adjacent projections 17 is about 10 times the length of the projection 17 in the circumferential direction.
進一步如圖所示，繞組載體9以在圓周方向上彼此有一段距離的兩個凸起17抵靠定子極6之相對的面，而以在圓周方向上彼此有一段距離的三個凸起17抵靠定子壁8。故，產生一個在圓周方向上與定子5有一段距離的部分，其以截面來看約佔圓周線的85%，因此，繞組載體9只以圓周延伸長度之約15%抵靠定子5。Further, as shown, the winding carrier 9 abuts against the opposite faces of the stator pole 6 with two projections 17 at a distance from each other in the circumferential direction, and has three projections 17 at a distance from each other in the circumferential direction. Abuts against the stator wall 8. Therefore, a portion which is spaced apart from the stator 5 in the circumferential direction is produced, which accounts for about 85% of the circumferential line in cross section, and therefore, the winding carrier 9 abuts against the stator 5 only by about 15% of the circumferential extension.
於是，繞組載體9與定子5亦只有線狀接觸，其肋狀凸起17之間的面或距離可被選擇，使得共振在轉速範圍之外。Thus, the winding carrier 9 is also in linear contact with the stator 5, and the face or distance between the rib-like projections 17 can be selected such that the resonance is outside the rotational speed range.
上述磁阻馬達1之特徵為具有高自體共振。馬達轉速範圍內的不利共振效應可被避免，此外，亦可避免其他機械干擾噪音，例如，喀喀聲。馬達由於定子殼10之橋部11及繞組載體9與定子5的點狀或線狀接觸，而降低振盪電平，故具有最小化之噪音。The above reluctance motor 1 is characterized by high self-resonance. Unfavorable resonance effects in the motor speed range can be avoided, and other mechanical interference noises, such as click sounds, can also be avoided. Since the motor has a point-like or linear contact with the stator 5 of the stator case 10 and the winding carrier 9 to reduce the oscillation level, the motor has minimized noise.
所有揭示特徵本身皆具有發明性質。本發明揭示之特徵完全包含於本案之申請專利範圍中。All revealing features are inherently inventive in nature. The features disclosed in the present invention are fully included in the scope of the patent application of the present application.
