=示非重*式與第十圖所示重4式之差異係在於J元G 與單70線關於侧時是否有重4的情形。第十—圖所示 刷電路板之制方式，係· t路板製作技娜線圈102成型 於電路板103上面。印刷電路板之排列方式基於空間與線圈可 繞圈數之限制，只能適用於小推進力之設計。非重疊集中式繞 組之排列方式雖可產生較大之推進力，但線圈之中空部份有許 多空間仍無法有效運用。重疊集中式繞組之排列方式可將非重 疊集中式繞組之排列方式中所無法運用之空間填滿，如此方能 產生優於印刷電路板之排列方式和非重憂集中式繞組之排列 方式於最小空間内產生最大推進力。 習用重疊集中式繞組之排列方式有很多種，如us 4,758,750所揭露的單元線圈排列方式係以三個單元線圈依序 重疊排列後固定於一絕緣元件，形成一扁平三相單元線圈組， 再將複數個扁平三相單元線圈組排列組合成線性馬達線圈組 合件。依此方式若要產生更大之推進力，必須組合更多之扁平 三相單元線圈組才可達成。然而，這將使線性馬達線圈組合件 之重量增加，且各扁平三相單元線圈組間之接合處強度不足會 造成剛性下降。 根據前述之缺點，WO 2004/017500 A1所揭露的線圈排列 3 201031082 ίίίί 了單元_重疊之方式’其巾單元_是由兩垂直方 向作用邊及兩轴向非作用邊構成一封閉之迴路， 折f後，單元線圈在轴向非作用邊交錯重疊而可$ 向緊密排列而成三相單元線圈組。由於複數個三相 ❹ 可以^樣地㈣連續交錯重4制喊—_組合件，=不會 產生别述各扁平三相單元線圈組之間銜接處之剛性不足 題，並能改善線性馬達線圈組合件之重量較重的缺點。單元^ 圈為了產生更大之推進力’必須有更多的繞線巫數，因此將辦 ^單7G線圈之厚度或寬度’較厚之單元線圈増加折-成型的^ 難度。另外，單元線圈彎折後之厚度至少是原單元線圈丨5倍 Ϊ以達到可44之目的’而且在組合成線性馬達線圈“ 件時為將各單元線圈做串並聯之接線，將會預留空間以為接線 擺放之位置，故在軸向非作用邊處之厚度上需要更大的空間。 因此’線圈組合件於軸向非作用邊處之總厚度至少為預留接線 空間厚度加上2倍的單元線圈厚度；另外在寬度較大之單元線 圈在彎曲至軸向非作用邊時其寬度將完全變成線圈長度之增 加量而造成在長度上更大的空間需求。 ❹ 如第十二圖所示，為習用單一之成型單元線圈7，以此重 疊排列組成三相單元線圈組31，則單元線圈7之軸向非作用 厚度為2倍的Τ6加上預留接線空間厚度Τ7。然而，成型 單元線圈7厚度Τ6越大則越困難成型且内側彆折半徑汜卜 R33與外侧彎折半徑幻2、汜4差異亦越大，而較小之内側聲 折半徑R3卜R33將造成絕緣不良之影響。 如第十三圖所示’若單元線圈8之寬度較寬，其寬度為 W3 ’則線圈寬度完全變成線圈成型後轴向兩非作用邊之高度 W3 ’因此線圈總高度變大，同時亦增加線性馬達線圈組合件 3如第一圖所示之組合高度。 如第十四圖⑻及(b)所示，線圈9b為習用之繞線方式係採 垂直堆4方式，故其中空部份92無漸縮情形而垂直向上，即 線圈中空部份之長度L4=L5，此會導致線圈9b彎折成型後， 201031082 如第十四圖(c)所示之線圈％’，其軸向非作用邊93,的端部呈 傾斜狀’其原因在於成型線圈9b，之内外側長度相同L4，=L5,， 外側長度L5’包含較大的彎折半徑R5，，而内側長度L4’所包含 — 的彎折半徑R4’較小，於是造成成型線圈卯，之轴向非作用邊 . 93’外側較内側内縮，如第十四圖(d)所示。線性馬達線圈組合 • 件3的厚度需求將因呈傾斜狀之軸向非作用邊93,而增加。 如第十五圖所示，習用組成線圈組合件之單元線圈間之接 線方式，可採用如第十五圖(a)之等效電路串聯接線方式產生較 大推力，或如第十五圖(b)之等效電路並聯接線方式產生較大 速度，亦或利用如第十五圖(c)之等效電路串並聯接線方式產生 罾 不同特性之線性馬達。然而，此接線方式只適用於單元線圈間 之接線，若是仍無法達成所期望之線性馬達特性，必須利用其 它方式來達成。 【發明内容】 - 本發明之目的為提供一線性馬達線圈組合件之設計，使組 成線性馬達線圈組合件之單元線圈不論其厚度皆成型容易且 ' 線，成型時可增加彎曲半徑而提高絕緣能力，進而增長線圈使 用壽命。 ▲本發明之另一目的為提供一線性馬達線圈組合件之設 ❹ 4 ’可有效減少線圈弯折時軸向非作用邊所需之厚度或彎i曲時 轴向非作用邊所需之長度，以提供更節省空間的設計' 根據上述之目的，本發明所提供之無鐵心式線性馬達係由 一線圈組合件和一磁軌所組成’其中該磁軌係由兩列正反置放 的複數個永久磁鐵所組成，以構成一列正反交替的磁 線圈組合件係由複數個三相單元線圈組轴向重4交錯排 再經由樹脂層加靖裝喊；該三相單元線圈組係由三組 ^同的單元線圈重4交錯排騎域，其巾單元_係由在抽 向，用邊有不同騎的複數個子線圈排列組成。線圈組合件 ㈣產生磁通與魏之磁場產生推進力而相互 運動。若將磁軌固定成為定子，則線圈組合件為動子；反之， 5 201031082 若將線圈組合件固定為定子，則磁軌為動子。 單元線圈由複數個子線圈經彎折後排列組成的方式可為 ，在軸向非作用邊有不同f折的複數個厚度較薄之子線圈在 厚度方向重核合^就度—樣厚度較厚的單元_ 4於子 線圈之厚度較薄且所ff曲之轉半徑可增A，故可大幅降低 =線圈_難度，因此容易製作；另外厚度較薄之子線圈所 需彎折之曲率摊可較大，除了子線圈於料處不容易因弯折 ^型而受損外，並且子線圈因電流通過所產生的熱能亦不易累 積在子，圈弯折處，因而能增加子線圈以及堆疊而成的單元線 圈使用壽命。用厚度較薄之子線圈所重4喊的單A線圈之厚 ^了以不受限制’依所需求之推進力大小由子線圈堆番出足 勹厚度之單元線圈，而不受單一單元線圈過厚不易彎折之限 ，。其中組成單元線圈之複數個子線圈，上層子線圈可適度縮 ，垂直方向長度’即上層線圈之垂直方向長度比下層線圈之垂 直方向長度短，且組成單元線圈之上層子線圈轴向非作用邊之 線圈截面區域在單元線圈之總厚度之上，於是減小組合後之單 元線圈整體厚度。 參 單元線圈由複數個子線圈經彎折後排列組成的方式可為 將在軸向非作用邊有不同彎折的複數個寬度較窄之子線圈緊 J排列成厚度-樣寬度較寬之單元線圈，並藉由子線圈轴向非 作用邊在厚度方向之重疊而減少組合後單元線圈垂直方向長 度之，求而可以適度調整線性馬達線圈組合件之總高度需求。 單元線圈由複數個子線圈經彎折後排列組成的方式可 將在軸向非作用邊有不同彎折的複數個大小不同但具同心狀 且寬度較窄之子線圈以同心排列方式組成厚度一樣寬度較 之單元線圈。藉由轴向非作用邊在厚度方向之重疊，在不増加 厚度下而減少組合後單元線圈垂直方向長度之需求而可^ 度調整線性馬達線圈組合件之總高度需求。 單元線圈由複數個子線圈經彎折後排列組成之方式亦 由上述兩種方式混合使用以達到本發明之目的。 6 201031082 本發明之另一目的為使得線圈彎折後仍能整齊排列，將線 圈於繞線時依預期折彎後之大小而事先繞出線圈在厚度部份 呈漸縮的形狀’其漸縮之定義為線圈在厚度方向一側之垂直方 向長度會比另一侧之垂直方向長度長，於是線圈沿厚度方向之 垂直方向長度漸漸縮小。此厚度方向呈現漸縮狀之線圈在彎折 成型後’成型線圈之軸向非作用邊即成齊頭的形狀因此可以縮 減線圈彎折所需之厚度。 由於單元線圈是由複數個子線圈堆疊排列而成，故可更靈 活地利用此單元線圈之各子線圈接線，例如以提供相等電流於 線圈組合件情況下，串聯接線組成的線性馬達線圈組合件之推 力常數會比並聯接線方式大；相對地，並聯接線方式組成的線 性馬達線圈組合件所產生之反電動勢常數較串聯方式為小。另 一種則是串並聯混合接線之方式，可依照等效電路之結果產生 不，的推力常數及反電動勢常數。一般來說，線性馬達會針對 單元線圈間之接線採用串聯、並聯與串並聯混合接線之方式來 達成不同特性之線性馬達。本發明組成單元線圈之各子線圈接 線亦可分為串聯、並聯與串並聯混合接線；單元線圈中各子線 圈接線^採用並聯之方式，則線性馬達可產生較大速度；反 單元線圈各子線圈接線若採用串聯方式，線性馬達可產生 ^推力。因此藉由單元線圈各子線關串聯、並聯或串並聯 接線，可達成範圍更廣的線性馬達特性。 【實施方式】 為了進一步描述本發明之結構，茲附以實施例之圖示詳細 説明如後： 、 圈紐^人第圖所示，無鐵心式線性馬達1係由一磁軌2和一線 、。件3組成，其中該磁拙?後忐兩列正反置放的複數個永The difference between the non-heavy* type and the tenth type shown in the tenth figure is the case where the J-G and the single-70 line have a weight of 4 on the side. The tenth-figure mode of the brush circuit board is formed on the circuit board 103 by the t-board fabrication technique. The arrangement of printed circuit boards is based on the limitation of the number of turns of the space and the coil, and can only be applied to the design of small propulsion. Although the arrangement of the non-overlapping centralized windings can generate a large propulsive force, the hollow portion of the coil has a lot of space and cannot be effectively used. The arrangement of the overlapping concentrated windings can fill the space that cannot be used in the arrangement of the non-overlapping concentrated windings, so that the arrangement of the printed circuit boards and the arrangement of the non-heavy concentrated windings can be minimized. The maximum propulsive force is generated in the space. There are many ways to arrange the overlapping concentrated windings. For example, the unit coil arrangement disclosed in US 4,758,750 is arranged in an overlapping manner by three unit coils and then fixed to an insulating element to form a flat three-phase unit coil group, and then A plurality of flat three-phase unit coil sets are arranged to be combined into a linear motor coil assembly. In this way, in order to generate greater propulsion, more flat three-phase unit coil sets must be combined to achieve this. However, this will increase the weight of the linear motor coil assembly, and insufficient joint strength between the flat three-phase unit coil groups will cause a decrease in rigidity. According to the aforementioned shortcomings, the coil arrangement 3 disclosed in WO 2004/017500 A1 is in the form of a unit_overlapment. The towel unit _ is formed by two perpendicularly acting edges and two axially inactive edges forming a closed loop. After f, the unit coils are staggered in the axially inactive side and can be closely aligned to form a three-phase unit coil group. Since a plurality of three-phase ❹ can be sampled (4) continuously interleaved and heavy 4 system shouting - _ assembly, = will not produce the rigidity of the joint between the flat three-phase unit coil group, and can improve the linear motor coil The disadvantage of the heavier weight of the assembly. In order to generate greater propulsion, the unit must have more windings, so the thickness or width of a single 7G coil should be increased. In addition, the thickness of the unit coil after bending is at least 5 times that of the original unit coil Ϊ to achieve the purpose of 44. And when combining the linear motor coils, the wiring of each unit coil is made in series and parallel, and will be reserved. Space assumes the location of the wiring, so more space is required at the thickness of the axially inactive side. Therefore, the total thickness of the coil assembly at the axially inactive side is at least the thickness of the reserved wiring space plus 2 The unit coil thickness is doubled; in addition, when the unit coil having a large width is bent to the axially inactive side, its width will completely become an increase in the length of the coil, resulting in a larger space requirement in length. ❹ As shown, in order to conventionally use a single unit coil 7 to form a three-phase unit coil group 31 in an overlapping arrangement, the axial non-active thickness of the unit coil 7 is 2 times 加上6 plus the reserved wiring space thickness Τ7. However, The larger the thickness Τ6 of the forming unit coil 7 is, the more difficult it is to form and the difference between the inner radius of the radius R33 and the outer bending radius of illusion 2, 汜4 is larger, and the smaller inner radius of curvature R3 R33 will cause If the width of the unit coil 8 is wider and the width is W3 ', the coil width is completely changed to the height of the two non-active sides of the axial direction after the coil is formed, so the total height of the coil becomes larger. At the same time, the combined height of the linear motor coil assembly 3 as shown in the first figure is also increased. As shown in the fourteenth (8) and (b), the coil 9b is a conventional winding method which adopts a vertical stack 4 method. The empty portion 92 has no taper and is vertically upward, that is, the length L4 of the hollow portion of the coil L4=L5, which causes the coil 9b to be bent and formed, 201031082 as shown in Fig. 14(c), the coil %', The axially inactive side 93 has an inclined end portion because the forming coil 9b has the same inner and outer lengths L4, = L5, and the outer length L5' includes a larger bending radius R5, and the inner length L4. 'Included—The bending radius R4' is small, thus causing the forming coil turns, the axially inactive side. The outer side of the 93' is retracted from the inside, as shown in Figure 14 (d). Linear motor coil combination • The thickness requirement of the piece 3 will be due to the inclined axially inactive edge 93, and As shown in the fifteenth figure, the wiring method between the unit coils which constitute the coil assembly can be used to generate a large thrust according to the equivalent circuit series connection method of the fifteenth figure (a), or as the fifteenth Figure (b) The equivalent circuit parallel connection method produces a large speed, or the linear circuit with different characteristics is generated by the equivalent circuit series-parallel connection method as shown in the fifteenth figure (c). However, this wiring method is only applicable. The wiring between the unit coils, if it is still unable to achieve the desired linear motor characteristics, must be achieved by other means. SUMMARY OF THE INVENTION - The object of the present invention is to provide a linear motor coil assembly design to make up a linear motor coil The unit coil of the assembly is easy to form and 'line' regardless of its thickness, and the bending radius can be increased during molding to increase the insulation capacity, thereby increasing the coil life. ▲ Another object of the present invention is to provide a linear motor coil assembly ❹ 4' which can effectively reduce the thickness required for the axially inactive side when the coil is bent or the length required for the axially inactive side when the curve is bent. In order to provide a more space-saving design, according to the above object, the ironless linear motor provided by the present invention is composed of a coil assembly and a magnetic track, wherein the magnetic track is placed by two columns of the front and the back. a plurality of permanent magnets are formed to form a row of alternating magnetic coil assemblies. The plurality of three-phase unit coil groups are axially weighted by 4 staggered rows and then shuffled via a resin layer; the three-phase unit coil assembly is The three sets of the same unit coils are 4 staggered in the riding range, and the towel unit_ is composed of a plurality of sub-coils arranged in the direction of the drawing and having different rides on the sides. The coil assembly (4) generates a magnetic flux and a magnetic field of Wei to generate a propulsive force and move each other. If the track is fixed as a stator, the coil assembly is a mover; otherwise, 5 201031082 If the coil assembly is fixed as a stator, the track is a mover. The unit coil is composed of a plurality of sub-coils which are bent and arranged, and the plurality of thin coils having different thicknesses in the axial non-active side are re-nucleated in the thickness direction, and the thickness is thicker. The thickness of the unit _4 is thinner and the radius of the turn of the φ curve can be increased by A, so that the coil _ difficulty can be greatly reduced, so that it is easy to manufacture; in addition, the curvature of the sub-coil of the thinner thickness can be larger. In addition to the fact that the sub-coil is not easily damaged by bending, the thermal energy generated by the sub-coil due to the passage of current is not easily accumulated in the sub-circle, so that the sub-coils and the stacked ones can be added. Unit coil life. The thickness of the single A coil that is shouted by the thinner sub-coil is unrestricted. The unit coil of the thickness of the sub-coil is not limited by the required propulsive force, and is not easily thickened by the single unit coil. The limit of bending,. Wherein the plurality of sub-coils forming the unit coil, the upper sub-coil can be appropriately contracted, and the vertical direction length, that is, the vertical direction length of the upper layer coil is shorter than the vertical direction length of the lower layer coil, and the axial non-active side of the layer sub-coil above the unit coil is formed. The coil cross-sectional area is above the total thickness of the unit coils, thus reducing the overall thickness of the combined unit coils. The reference unit coil is formed by bending a plurality of sub-coils, and the plurality of sub-coils having different widths in the axial non-active side are arranged in a tightly-divided unit coil having a wide thickness-like width. Moreover, the vertical direction length of the combined unit coils is reduced by overlapping the axially inactive sides of the sub-coils in the thickness direction, so that the total height requirement of the linear motor coil assembly can be appropriately adjusted. The unit coil is composed of a plurality of sub-coils which are bent and arranged to form a plurality of sub-coils of different sizes but concentric and narrow in width, which are concentrically arranged in a concentric arrangement. The unit coil. By adjusting the axially inactive edges in the thickness direction, the total height requirement of the linear motor coil assembly can be adjusted by reducing the need for the vertical length of the combined unit coils without increasing the thickness. The unit coil is composed of a plurality of sub-coils which are bent and arranged, and is also used in combination by the above two methods to achieve the object of the present invention. 6 201031082 Another object of the present invention is to make the coils evenly aligned after being bent, and to wind the coils in a tapered shape in the thickness portion before the winding is wound according to the expected size. It is defined that the length of the coil in the vertical direction on one side in the thickness direction is longer than the length in the vertical direction on the other side, so that the length of the coil in the vertical direction in the thickness direction gradually decreases. The coil having a tapered shape in the thickness direction is formed into a shape in which the axially inactive side of the forming coil is formed into a head shape after the bending is formed, so that the thickness required for the bending of the coil can be reduced. Since the unit coil is formed by stacking a plurality of sub-coils, each sub-coil wiring of the unit coil can be utilized more flexibly, for example, to provide an equal current in the case of the coil assembly, and a linear motor coil assembly composed of a series connection The thrust constant is larger than that of the parallel connection; in contrast, the linear motor coil assembly composed of the parallel wiring method produces a counter electromotive force constant that is smaller than the series connection. The other is a series-parallel hybrid wiring method, which can generate a thrust constant and a counter electromotive force constant according to the result of the equivalent circuit. In general, linear motors use series, parallel, and series-parallel hybrid wiring for the wiring between the unit coils to achieve linear motors with different characteristics. The sub-coil wiring of the unit coil of the invention can also be divided into series, parallel and series-parallel hybrid wiring; each sub-coil wiring in the unit coil is connected in parallel, the linear motor can generate a large speed; the anti-unit coil each If the coil wiring is in series, the linear motor can generate the thrust. Therefore, by connecting the series, parallel or series-parallel connection of each sub-line of the unit coil, a wider range of linear motor characteristics can be achieved.

The coil assembly 3 is axially arranged by a plurality of three-phase U, V, and staggered overlaps, and then passed through the resin layer 32 to 201031082 as shown in the fourth figure ( As shown in a) and (b), the first embodiment of the present invention overlaps the two sub-coils 41, 42 having different thicknesses of T1 and T2 at different axially inactive sides to form a unit having a width of T6. The coil 7 is as shown in the twelfth figure. Since the individual sub-coils 41 and 42 are thin in thickness, they are easily bent and formed. Here, the upper and lower layer sub-coils 42, 41 may be two or more unit coils which are differently bent in the axially inactive side and which are overlapped in the thickness direction to form a unit coil having a relatively thick thickness. Since the thickness of the sub-coils is thin, the inner and outer bending radii of the sub-coils 41, 42 are narrower than the R12-R11, R14-R13, R22-R21 and R24-R23.
