Description
本発明は、モータに関する。 The present invention relates to a motor.
従来、モータのステータとして、周方向に環状に並べられた複数のコイルを備えるステータが広く知られている。このようなモータのステータは、例えば、特許文献１に開示される。 2. Description of the Related Art Conventionally, a stator having a plurality of coils arranged in an annular shape in the circumferential direction is widely known as a stator for a motor. A stator of such a motor is disclosed in Patent Document 1, for example.
特許文献１のステータは、周方向に複数配置された分割コアから構成されるステータコアを有する。各分割コアは、円弧状の連結部と、当該連結部の周方向中央部から径方向内側に延びるティースと、を有する。各分割コアには、絶縁性を有するインシュレータが装着される。各ティースにインシュレータの上から導線が巻き回されることにより、複数のコイルが形成される。各コイルからは、軸方向一方側に引出線が引き出される。 The stator of Patent Document 1 has a stator core composed of a plurality of divided cores arranged in the circumferential direction. Each divided core has an arc-shaped connecting portion and teeth extending radially inward from the circumferential central portion of the connecting portion. Each divided core is provided with an insulator having an insulating property. A plurality of coils are formed by winding a conductive wire around each of the teeth from above the insulator. From each coil, a leader line is drawn out to one side in the axial direction.
そして、特許文献１のステータでは、周方向に隣接する引出線同士の隙間の周方向幅は、全て同一である。すなわち、引出線同士の隙間は、全て等間隔である。 And in the stator of patent document 1, the circumferential direction width | variety of the clearance gap between the leader lines adjacent to the circumferential direction is all the same. That is, the gaps between the leader lines are all equally spaced.
特許文献１のモータには、ステータ以外に、引出線同士を短絡すると共に外部から供給される電流を各コイルに供給するためのバスバーが備えられる。各引出線は、バスバーに設けられる複数の各接続部に接続固定される。接続部同士の周方向の隙間は全て等間隔であるので、先述のように引出線同士の隙間も対応して等間隔である。 In addition to the stator, the motor of Patent Document 1 includes a bus bar for short-circuiting the lead wires and supplying a current supplied from the outside to each coil. Each leader line is connected and fixed to each of a plurality of connecting portions provided on the bus bar. Since the circumferential gaps between the connecting portions are all equally spaced, the gaps between the leader lines are also equally spaced as described above.
しかしながら、バスバーの仕様として接続部同士の隙間が一部等間隔でない箇所が存在する場合、引出線同士の隙間が全て等間隔であることは望ましくない。 However, when there are locations where the gaps between the connecting portions are not partly equally spaced as the specifications of the bus bar, it is not desirable that all the gaps between the leader lines are equally spaced.
また、モータの組立て性を向上させる目的で、引出線を所定位置に位置決めする治具を導入する場合にも、引出線同士の隙間が全て等間隔であることは必ずしも望ましいことではない。 Further, even when a jig for positioning the leader lines at a predetermined position is introduced for the purpose of improving the assembly of the motor, it is not always desirable that all the gaps between the leader lines are equal.
上記状況に鑑み、本発明は、コイルの引出線同士の間隔が全て等間隔であることによる不都合を解消することが可能なモータを提供することを目的とする。 In view of the above situation, an object of the present invention is to provide a motor that can eliminate the inconvenience caused by the fact that the intervals between the coil lead wires are all equal.
本発明の例示的なモータは、上下方向に延びる中心軸を有するステータと、前記ステータに対して相対回転可能なロータと、を備え、
前記ステータは、周方向に所定の間隔を空け、コイルから軸方向に引き出される複数の引出線を有し、
周方向に隣接する前記引出線の間に形成される隙間は、周方向幅が最大の隙間を含む１または複数の第１隙間と、周方向幅が前記第１隙間よりも小さい１または複数の第２隙間と、を有する。
An exemplary motor of the present invention includes a stator having a central axis extending in the up-down direction, and a rotor rotatable relative to the stator,
The stator has a plurality of lead lines that are spaced apart from each other in the circumferential direction at predetermined intervals in the circumferential direction, and are drawn out in the axial direction from the coil.
The gap formed between the leader lines adjacent in the circumferential direction includes one or more first gaps including a gap having the largest circumferential width, and one or more gaps having a circumferential width smaller than the first gap. A second gap.

＜２．ステータの構成＞
次に、ステータ２の構成について詳細に説明する。図２は、ステータ２の上面図である。図３は、ステータ２の斜視図である。
<2. Structure of stator>
Next, the configuration of the stator 2 will be described in detail. FIG. 2 is a top view of the stator 2. FIG. 3 is a perspective view of the stator 2.
ステータ２、中心軸ＣＬを中心とする略円環状である。ステータ２は、ステータコア２１と、インシュレータ２２と、コイル２３と、絶縁シート２４と、を有する。 The stator 2 has a substantially annular shape centered on the central axis CL. The stator 2 includes a stator core 21, an insulator 22, a coil 23, and an insulating sheet 24.
ステータコア２１は、複数枚の磁性鋼板を軸方向（上下方向）に積層して形成される。ステータコア２１は、コアバック２１Ａと、ティース２１Ｂと、を有する。コアバック２１Ａは、中心軸ＣＬを中心とする略円環状である。ティース２１Ｂは、コアバック２１Ａの内周部から径方向内側に中心軸ＣＬに向かって延び、上面視で略Ｔ字形状である。本実施形態では、一例として、ティース２１Ｂは、１２個が周方向に所定の間隔をあけて、並べて配置される。 The stator core 21 is formed by laminating a plurality of magnetic steel plates in the axial direction (vertical direction). The stator core 21 includes a core back 21A and teeth 21B. The core back 21A has a substantially annular shape centered on the central axis CL. The teeth 21B extend radially inward from the inner peripheral portion of the core back 21A toward the central axis CL, and have a substantially T shape in a top view. In the present embodiment, as an example, twelve teeth 21B are arranged side by side at a predetermined interval in the circumferential direction.
インシュレータ２２は、ティース１１Ｂの内周部を除く外面に設けられる。インシュレータ２２は、ステータコア２１とコイル２３との間に配置される。インシュレータ２２は、例えば合成樹脂材で構成される。コイル２３は、インシュレータ２２を介してティース１１Ｂの外周に導線が巻き回されて形成される。図２では、コイル２３は、１２個が周方向に配列される。 The insulator 22 is provided on the outer surface excluding the inner peripheral portion of the tooth 11B. The insulator 22 is disposed between the stator core 21 and the coil 23. The insulator 22 is made of, for example, a synthetic resin material. The coil 23 is formed by winding a conductive wire around the teeth 11 </ b> B via the insulator 22. In FIG. 2, twelve coils 23 are arranged in the circumferential direction.
絶縁シート２４は、隣接するコイル２３の間に挿入されて配置され、コイル２３の間の絶縁を図る。絶縁シート２４は、例えばアラミド紙やＰＥＴ材等からなる短冊状の部材であり、隣接するコイル２３の間に挿入される。絶縁シート２４は、上端が折り曲げられ、コイル２３の上面に引っ掛けられる。なお、図２、図３では、絶縁シート２４の折り曲げ部分を引出線２３１が貫通する形態が図示されているが、絶縁シート２４の折り曲げ部分が引出線２３１を避ける形態にすることもできる。 The insulating sheet 24 is inserted and disposed between the adjacent coils 23 to insulate between the coils 23. The insulating sheet 24 is a strip-shaped member made of, for example, aramid paper or PET material, and is inserted between adjacent coils 23. The insulating sheet 24 is bent at the upper end and hooked on the upper surface of the coil 23. 2 and 3, the lead wire 231 penetrates the bent portion of the insulating sheet 24, but the bent portion of the insulating sheet 24 can also avoid the lead wire 231.
ステータ２は、周方向に環状に並べられた複数の分割コア部２００を有する。図２では、分割コア部２００は、ステータ２に１２個備えられる。１２個の分割コア部２００は、周方向に環状に並べられて、組み合わされて、環状のステータ２として形成される。分割コア部２００は各々、弧状のコアバック２１Ａ１と、１個のティース２１Ｂと、インシュレータ２２Ａと、コイル２３と、を有する。分割コア部２００は、コアバック２１Ａ１の外周面に、軸方向に延びる溝部２１Ｃを有する。 The stator 2 has a plurality of divided core portions 200 arranged in a ring shape in the circumferential direction. In FIG. 2, twelve divided core portions 200 are provided in the stator 2. The twelve divided core portions 200 are annularly arranged in the circumferential direction and combined to form the annular stator 2. Each of the split core portions 200 includes an arc-shaped core back 21 </ b> A <b> 1, one tooth 21 </ b> B, an insulator 22 </ b> A, and a coil 23. The split core portion 200 has a groove portion 21C extending in the axial direction on the outer peripheral surface of the core back 21A1.
図２では、ステータ２は、複数の分割コア部２００各々から延びる、１２本の引出線２３１を有する。引出線２３１は各々、コイル２３から離隔する方向に、軸方向に沿って引き出される。 In FIG. 2, the stator 2 has twelve lead wires 231 extending from each of the plurality of divided core portions 200. The lead wires 231 are each drawn along the axial direction in a direction away from the coil 23.
１２本の引出線２３１は各々、第１直線部２３１Ａと、第２直線部２３１Ｂと、を有する。第１直線部２３１Ａは、第２直線部２３１Ｂよりもコイル２３に近く、軸方向と交差する方向に延びる。第２直線部２３１Ｂは、コイル２３から第１直線部２３１Ａを隔てて離れ、軸方向に沿って上方に向かって延びる。第２直線部２３１Ｂの上端は、後述するバスバー（図２で不図示）に接続される。 Each of the 12 lead lines 231 includes a first straight line portion 231A and a second straight line portion 231B. The first straight portion 231A is closer to the coil 23 than the second straight portion 231B and extends in a direction intersecting the axial direction. The second straight portion 231B is spaced apart from the coil 23 with the first straight portion 231A, and extends upward along the axial direction. The upper end of the second straight portion 231B is connected to a bus bar (not shown in FIG. 2) described later.
なお、このような第１直線部２３１Ａと第２直線部２３１Ｂを有する引出線２３１は、ステータ２の製造時に、一本の直線状に軸方向に引き出された引出線をＬ字形状に成形することにより構成される。但し、バスバーの仕様等によっては、Ｌ字形状への成形を行うことは必須ではない。 The lead wire 231 having the first straight portion 231 </ b> A and the second straight portion 231 </ b> B is formed into an L shape in the shape of a single lead wire drawn in the axial direction when the stator 2 is manufactured. It is constituted by. However, depending on the specifications of the bus bar and the like, it is not essential to form the L-shape.
１２個の分割コア部２００よりステータ２を組み立てる方法について説明する。図４は、ステータ２の組み立てに使用する一対の分割コア部を示す斜視図である。一対の分割コア部２００のうち一方のティース２１Ｂに導線を巻き回すことで１個のコイル２３が形成される。そのコイル２３の巻き終わりの導線を他方の分割コア部２００におけるティース２１Ｂに巻き回すことで、他のコイル２３が形成される。これにより、一対の分割コア部２００の間に導線が跨ぐことで、渡り線２３２が形成される。また、引出線２３１は、一対の分割コア部２００における、一方のコイル２３の巻き始めと、他方のコイル２３の巻き終わりによって２本形成されることとなる。そして、図４に示すように、このような渡り線２３２で接続された一対の分割コア部２００を、３組製造する。なお、渡り線２３２は、絶縁チューブにより被覆される。 A method for assembling the stator 2 from the twelve divided core portions 200 will be described. FIG. 4 is a perspective view showing a pair of split core portions used for assembling the stator 2. One coil 23 is formed by winding a conductive wire around one tooth 21 </ b> B of the pair of split core portions 200. The other coil 23 is formed by winding the winding end conductor of the coil 23 around the tooth 21 </ b> B in the other divided core portion 200. As a result, the connecting wire 232 is formed by the conductive wire straddling between the pair of split core portions 200. In addition, two lead wires 231 are formed by the start of winding of one coil 23 and the end of winding of the other coil 23 in the pair of split core portions 200.

In the second divided core group 2002, between one pair of divided core parts 200G and 200J, one divided core part 200H, 200I of the other pair of divided core parts is arranged. Similarly, one split core part 200I, 200J of the other pair of split core parts is disposed between the pair of split core parts 200H and 200K, and the other between the pair of split core parts 200I and 200L. One split core portion 200J, 200K of the pair of split core portions is disposed.
これにより、分割コア部２００Ｇの周方向一方側端部から上側に引き出される渡り線２３２は、分割コア部２００Ｈ、２００Ｉの上面を通って、分割コア部２００Ｊの周方向他方側端部に引き回される。分割コア部２００Ｈの周方向一方側端部から上側に引き出される渡り線２３２は、分割コア部２００Ｉ、２００Ｊの上面を通って、分割コア部２００Ｋの周方向他方側端部に引き回される。分割コア部２００Ｉの周方向一方側端部から上側に引き出される渡り線２３２は、分割コア部２００Ｊ、２００Ｋの上面を通って、分割コア部２００Ｌの周方向他方側端部に引き回される。 As a result, the crossover wire 232 drawn upward from one end portion in the circumferential direction of the split core portion 200G passes through the upper surfaces of the split core portions 200H and 200I and is routed to the other end portion in the circumferential direction of the split core portion 200J.

The connecting wire 232 drawn upward from the one end portion in the circumferential direction of the split core portion 200H passes through the upper surfaces of the split core portions 200I and 200J and is routed to the other end portion in the circumferential direction of the split core portion 200K. The connecting wire 232 drawn upward from the one end portion in the circumferential direction of the split core portion 200I passes through the upper surfaces of the split core portions 200J and 200K and is routed to the other end portion in the circumferential direction of the split core portion 200L.
また、引出線２３１は、分割コア部２００Ｇ〜２００Ｉの各周方向他方側端部、および分割コア部２００Ｊ〜２００Ｌの各周方向一方側端部から上側に引き出される。すなわち、第２分割コア群２００２において、引出線２３１は、６本引き出される。 In addition, the leader line 231 is drawn upward from the other circumferential end of each of the split core portions 200G to 200I and the one circumferential end of each of the split core portions 200J to 200L. That is, in the second divided core group 2002, six lead lines 231 are drawn.
ステータ２における１２本の引出線２３１は、それぞれ先述したように第１直線部２３１Ａと第２直線部２３１Ｂを有するＬ字形状に成形され、第２直線部２３１Ｂの端部は、上面視で同一円上に配置される。 The 12 lead wires 231 in the stator 2 are each formed into an L shape having the first straight portion 231A and the second straight portion 231B as described above, and the end portions of the second straight portion 231B are the same in a top view. Arranged on a circle.
図２では、中心軸ＣＬから周方向に隣接する第２直線部２３１Ｂを通るように延びる２つの線分間の角度をθ１〜θ４で示している。第２接続部ＣＮ２で接続される隣接する分割コア部２００Ｆ、２００Ｌのそれぞれにおいて引き出される引出線２３１は、共に、周方向一方側端部から引出されるため、これらの引出線２３１の第２直線部２３１Ｂの隙間に対応する角度θ１は、比較的に大きな角度となる。同様に、第１接続部ＣＮ１で接続される隣接する分割コア部２００Ａ、２００Ｇのそれぞれにおいて引き出される引出線２３１は、共に、周方向他方側端部から引出されるため、これらの引出線２３１の第２直線部２３１Ｂの隙間に対応する角度θ２も、比較的に大きな角度となる。 In FIG. 2, angles of two line segments extending from the central axis CL so as to pass through the second linear portions 231 </ b> B adjacent in the circumferential direction are denoted by θ <b> 1 to θ <b> 4. Since the lead lines 231 drawn out in each of the adjacent divided core parts 200F and 200L connected by the second connection part CN2 are both drawn out from one end in the circumferential direction, the second straight lines of these lead lines 231 The angle θ1 corresponding to the gap between the portions 231B is a relatively large angle. Similarly, the lead wires 231 drawn out in each of the adjacent divided core portions 200A and 200G connected by the first connection portion CN1 are both drawn out from the other end portion in the circumferential direction. The angle θ2 corresponding to the gap between the second straight portions 231B is also a relatively large angle.
より具体的には、図２において、角度の大小関係は、θ１＞θ２＞θ３＞θ４となる。すなわち、θ１は、全ての角度において最大であり、θ２は、全ての角度において２番目に大きい。従って、θ１に対応する第２直線部２３１Ｂ間の隙間の周方向幅は最大となり、θ２に対応する第２直線部２３１Ｂ間の隙間の周方向幅は２番目に大きい。このような周方向幅が比較的に大きくなる隙間として、図２のように、第１隙間Ｌ１が形成される。そして、比較的に小さい角度であるθ３およびθ４に対応する第２直線部２３１Ｂ間の隙間の周方向幅は、第１隙間Ｌ１の周方向幅よりも小さい。このような周方向幅が比較的に小さくなる隙間として、図２のように、第２隙間Ｌ２が形成される。すなわち、２個の第１隙間Ｌ１と、１０個の第２隙間Ｌ２が形成される。 More specifically, in FIG. 2, the angle relationship is θ1> θ2> θ3> θ4. That is, θ1 is the maximum at all angles, and θ2 is the second largest at all angles. Accordingly, the circumferential width of the gap between the second straight portions 231B corresponding to θ1 is the maximum, and the circumferential width of the gap between the second straight portions 231B corresponding to θ2 is the second largest. As such a gap having a relatively large circumferential width, a first gap L1 is formed as shown in FIG. The circumferential width of the gap between the second linear portions 231B corresponding to θ3 and θ4, which are relatively small angles, is smaller than the circumferential width of the first gap L1. As such a gap having a relatively small circumferential width, a second gap L2 is formed as shown in FIG. That is, two first gaps L1 and ten second gaps L2 are formed.
このように比較的に大きい第１隙間Ｌ１を形成することにより、後述するような引出線を位置決めする治具を第１隙間Ｌ１に挿入することが容易となり、モータＡの組み立て性を向上できる。また、後述する引出線が接続固定される接続部の配置が等間隔でないバスバーに対応することも可能となる。 By forming the relatively large first gap L1 in this way, it becomes easy to insert a jig for positioning a leader line, which will be described later, into the first gap L1, and the assemblability of the motor A can be improved. In addition, it is possible to correspond to bus bars in which the arrangement of connecting portions to which lead lines described later are connected and fixed is not equally spaced.

このような構成により、引出線の間隔が等間隔でなくなり、等間隔であることによる不都合を解消することが可能となる。なお、この不都合とは、治具を挿入する際の不都合、およびバスバーの仕様に対する不都合に限らず、それ以外の不都合であってもよい。 With such a configuration, the intervals between the leader lines are not equal, and the inconvenience due to the equal intervals can be eliminated. This inconvenience is not limited to inconvenience when inserting a jig and inconvenience with respect to the specifications of the bus bar, but may be other inconveniences.
また、図２の実施例では、複数の第１隙間Ｌ１は周方向幅がお互い異なる大きさとしたが、同じ大きさとしてもよい。また、第１隙間Ｌ１は、２つに限らず、３つ以上の複数としてもよいし、１つのみとしてもよい。第２隙間Ｌ２は、複数に限らず、１つのみとしてもよい。また、上記実施形態では、第２隙間Ｌ２は、角度θ３に対応する箇所のみその他のθ４に対応する箇所より周方向幅を大きくしたが、全てで同じ大きさであるようにしてもよい。第１隙間と第２隙間は、個数に依らず、第１隙間が総じて第２隙間より周方向幅が大きなものであれば、種々の実施形態を採りうる。 In the embodiment of FIG. 2, the plurality of first gaps L1 have different circumferential widths, but may have the same size. Further, the first gap L1 is not limited to two, and may be a plurality of three or more, or only one. The second gap L2 is not limited to a plurality and may be only one. In the above-described embodiment, the second gap L2 has a circumferential width larger than that of the other portions corresponding to θ4 only in the portion corresponding to the angle θ3, but may be the same size in all. Various embodiments can be adopted as long as the first gap is generally larger in the circumferential width than the second gap, regardless of the number of the first gap and the second gap.

＜３．引出線位置決め工程について＞
次に、先述のようにステータ２において引出線２３１の第１隙間Ｌ１および第２隙間Ｌ２を形成することに関連し、引出線２３１の治具を用いた位置決め工程について詳細に説明する。以下、各種工程の順に説明する。
<3. Leader positioning process>
Next, in relation to forming the first gap L1 and the second gap L2 of the lead wire 231 in the stator 2 as described above, the positioning process using the jig of the lead wire 231 will be described in detail. Hereinafter, it demonstrates in order of various processes.

引出線位置決め装置１００は、載置台に加えて、図５に示す内側位置決め部材１１０を有する。 The leader line positioning device 100 includes an inner positioning member 110 shown in FIG. 5 in addition to the mounting table.
内側位置決め部材１１０は、引出線２３１の位置決めの前段階において、ステータ２の径方向外側に配置される。内側位置決め部材１１０は、例えば４個が設けられる。２個の内側位置決め部材１１０が、一対の挿入部材１３０各々に設けられる。すなわち、引出線位置決め装置１００では、一対の挿入部材１３０が２組用いられる。一対の挿入部材１３０は、移動機構（図示略）によって、引出線２３１に対して接近、離隔する方向への移動と、挿入部材１３０の回動と、が可能である。 The inner positioning member 110 is disposed on the outer side in the radial direction of the stator 2 in the stage before positioning of the lead wire 231. For example, four inner positioning members 110 are provided. Two inner positioning members 110 are provided in each of the pair of insertion members 130. That is, in the leader line positioning device 100, two pairs of the insertion members 130 are used. The pair of insertion members 130 can move in a direction to approach and separate from the lead wire 231 and rotate the insertion member 130 by a moving mechanism (not shown).
一対の挿入部材１３０からなる治具は、図５および図６に示すように、所謂はさみ形状で構成され、挿入部材１３０は、互いが軸方向に沿って延びる回転軸１３１回りに回動可能である。挿入部材１３０は、はさみの２枚の刃各々に相当する領域を閉じた状態において、径方向に沿って延びる。内側位置決め部材１１０は、挿入部材１３０の径方向内側の先端部に配置される。２個の内側位置決め部材１１０が、挿入部材１３０の、はさみの２枚の刃各々に相当する領域に個別に設けられる。内側位置決め部材１１０は、その径方向外側に配置された回転軸１３１回りに、挿入部材１３０とともに回転可能である（図８参照）。 As shown in FIGS. 5 and 6, the jig composed of the pair of insertion members 130 is formed in a so-called scissor shape, and the insertion members 130 are rotatable around a rotation shaft 131 that extends along the axial direction. is there. The insertion member 130 extends along the radial direction in a state where the regions corresponding to the two blades of the scissors are closed. The inner positioning member 110 is disposed at the distal end portion on the radially inner side of the insertion member 130. Two inner positioning members 110 are individually provided in an area of the insertion member 130 corresponding to each of the two scissors blades. The inner positioning member 110 can be rotated together with the insertion member 130 around the rotation shaft 131 disposed on the outer side in the radial direction (see FIG. 8).
４個の内側位置決め部材１１０は各々、３個の凹部１１１を個別に有する。凹部１１１は、内側位置決め部材１１０を引出線２３１に対して中心軸ＣＬ側に配置した場合の、内側位置決め部材１１０の、引出線２３１との対向領域に設けられ、軸方向と交差する方向に沿って引出線２３１から離れる方向に窪む。凹部１１１は、引出線２３１を受け入れ可能な形状、大きさを有する。 Each of the four inner positioning members 110 has three recesses 111 individually. The concave portion 111 is provided in a region facing the leader line 231 of the inner positioning member 110 when the inner positioning member 110 is disposed on the center axis CL side with respect to the leader line 231, and extends along a direction intersecting the axial direction. And is recessed in a direction away from the leader line 231. The recess 111 has a shape and a size that can receive the lead wire 231.
凹部１１１は、引出線２３１の中心軸ＣＬ側から、引出線２３１に接触可能である。さらに、内側位置決め部材１１０は、３個の凹部１１１を有するので、単一で３本の引出線２３１に、引出線２３１の中心軸ＣＬ側から接触する。単一の内側位置決め部材１１０に設けられた３個の凹部１１１によって、軸方向と交差する方向に関して、３本の引出線２３１の間隔、位置関係が明確に規定される。この構成によれば、部品点数の低減を図ることができる。また、内側位置決め部材１１０の配置に係る作業性を向上させることが可能である。 The concave portion 111 can contact the lead wire 231 from the center axis CL side of the lead wire 231. Furthermore, since the inner positioning member 110 has the three concave portions 111, the inner positioning member 110 comes into contact with the three lead wires 231 from the center axis CL side of the lead wire 231. The three recesses 111 provided in the single inner positioning member 110 clearly define the interval and positional relationship of the three lead lines 231 with respect to the direction intersecting the axial direction. According to this configuration, the number of parts can be reduced. In addition, the workability related to the arrangement of the inner positioning member 110 can be improved.
内側位置決め部材１１０は、図６および図７に示すように、径方向内側位置決め部材１１０Ａと、周方向内側位置決め部材１１０Ｂと、を含む。径方向内側位置決め部材１１０Ａおよび周方向内側位置決め部材１１０Ｂは、互いが軸方向に並べて配置される。径方向内側位置決め部材１１０Ａおよび周方向内側位置決め部材１１０Ｂは各々、軸方向と交差する方向に関して、同じ位置に凹部１１１Ａ、１１１Ｂを有する。凹部１１１は、凹部１１１Ａおよび凹部１１１Ｂを含む。 As shown in FIGS. 6 and 7, the inner positioning member 110 includes a radially inner positioning member 110A and a circumferential inner positioning member 110B. The radially inner positioning member 110A and the circumferential inner positioning member 110B are arranged side by side in the axial direction. Each of the radially inner positioning member 110A and the circumferential inner positioning member 110B has recesses 111A and 111B at the same position in the direction intersecting the axial direction. The recess 111 includes a recess 111A and a recess 111B.
径方向内側位置決め部材１１０Ａは、挿入部材１３０と同一部材として構成される。径方向内側位置決め部材１１０Ａは、３個の凹部１１１Ａを有する。凹部１１１Ａは、周方向内側位置決め部材１１０Ｂの凹部１１１Ｂよりも緩やかな曲面の壁面、例えば円弧形状の壁面を有する。この形状の凹部１１１Ａによって、径方向内側位置決め部材１１０Ａは、引出線２３１の径方向の位置決めを行う。 The radially inner positioning member 110 </ b> A is configured as the same member as the insertion member 130. The radially inner positioning member 110A has three recesses 111A. The recess 111A has a curved wall surface that is gentler than the recess 111B of the circumferential inner positioning member 110B, for example, an arc-shaped wall surface. The radially inner positioning member 110A performs the radial positioning of the lead wire 231 by the recess 111A having this shape.
周方向内側位置決め部材１１０Ｂは、径方向内側位置決め部材１１０Ａの軸方向下面に接触させて、配置される。周方向内側位置決め部材１１０Ｂは、３個の凹部１１１Ｂを有する。凹部１１１Ｂは、径方向内側位置決め部材１１０Ａの凹部１１１Ａよりも急峻な曲面の壁面、例えばＶ字形状の壁面を有する。この形状の凹部１１１Ｂによって、周方向内側位置決め部材１１０Ｂは、引出線２３１の周方向の位置決めを行う。 The circumferential inner positioning member 110B is arranged in contact with the axially lower surface of the radial inner positioning member 110A. The circumferential inner positioning member 110B has three concave portions 111B. The recess 111B has a curved wall surface that is steeper than the recess 111A of the radially inner positioning member 110A, for example, a V-shaped wall surface. The circumferential inner positioning member 110B positions the leader line 231 in the circumferential direction by the concave portion 111B having this shape.
内側位置決め部材１１０は、凹部１１１Ａ、１１１Ｂによって、径方向および周方向において、引出線２３１の位置決めを行う。径方向内側位置決め部材１１０Ａと周方向内側位置決め部材１１０Ｂとを組み合わせることで、引出線２３１を適正な位置に位置決めすることが可能である。 The inner positioning member 110 positions the lead wire 231 in the radial direction and the circumferential direction by the recesses 111A and 111B. By combining the radially inner positioning member 110A and the circumferential inner positioning member 110B, the lead wire 231 can be positioned at an appropriate position.
なお、一対の挿入部材１３０は、互いが交差して回動するが、交差しない構成であっても良い。また、径方向内側位置決め部材１１０Ａを、挿入部材１３０の別部材として構成しても良い。そして、周方向内側位置決め部材１１０Ｂを、挿入部材１３０と同一部材として構成しても良い。 In addition, although a pair of insertion member 130 mutually cross | intersects and rotates, the structure which does not cross | intersect may be sufficient. Further, the radially inner positioning member 110 </ b> A may be configured as a separate member of the insertion member 130. The circumferential inner positioning member 110B may be configured as the same member as the insertion member 130.
内側位置決め部材１１０の配置工程において、内側位置決め部材１１０は、図９に示すように、一対の挿入部材１３０を閉じた状態にして、隣り合う引出線２３１同士の隙間である第１隙間Ｌ１を通して、引出線２３１の中心軸ＣＬ側に、ステータ２の径方向外側から挿入される。すなわち、一対の挿入部材１３０は、互いの内側位置決め部材１１０の、引出線２３１の中心軸ＣＬ側に対する挿入、抜去のときに、互いが回動されて互いの内側位置決め部材１１０が接近される。 In the arrangement process of the inner positioning member 110, as shown in FIG. 9, the inner positioning member 110 closes the pair of insertion members 130 and passes through the first gap L1 that is the gap between the adjacent leader lines 231. The lead wire 231 is inserted from the radially outer side of the stator 2 on the center axis CL side. That is, the pair of insertion members 130 are rotated with each other when the inner positioning members 110 are inserted into and removed from the central axis CL side of the lead wire 231, and the inner positioning members 110 are brought closer to each other.
続いて、内側位置決め部材１１０は、図１０に示すように、一対の挿入部材１３０の、所謂はさみを開くことで、２個の内側位置決め部材１１０各々を径方向外側に向けて移動させる。内側位置決め部材１１０は、３個の凹部１１１の部分が径方向外側に引出線２３１に向かって移動する。内側位置決め部材１１０は、３個の凹部１１１が各々、引出線２３１の中心軸ＣＬ側から、３本の引出線２３１に接触する。すなわち、一対の挿入部材１３０は、互いの内側位置決め部材１１０の、引出線２３１に対する接触のときに、互いが回動されて互いの内側位置決め部材１１０が離隔される。この構成によれば、所謂はさみ形状で構成された一対の挿入部材１３０の、はさみの２枚の刃各々に相当する領域を開くことで、引出線２３１の中心軸ＣＬ側における内側位置決め部材１１０の移動が容易になる。 Subsequently, as illustrated in FIG. 10, the inner positioning member 110 moves each of the two inner positioning members 110 radially outward by opening so-called scissors of the pair of insertion members 130. In the inner positioning member 110, the three concave portions 111 move radially outward toward the leader line 231. In the inner positioning member 110, the three concave portions 111 come into contact with the three lead wires 231 from the center axis CL side of the lead wire 231. That is, the pair of insertion members 130 are rotated with each other and the inner positioning members 110 are separated from each other when the inner positioning members 110 are in contact with the lead wires 231. According to this configuration, by opening an area corresponding to each of the two blades of the scissors of the pair of insertion members 130 configured in a so-called scissor shape, the inner positioning member 110 on the central axis CL side of the leader line 231 is formed. Easy to move.

FIG. 12 is a plan view showing a positioning step of the leader line 231 in the method for manufacturing the motor A according to the embodiment of the present invention. FIG. 13 is a longitudinal cross-sectional view showing the positioning process of the lead wire 231 in the method for manufacturing the motor A according to the embodiment of the present invention. 13 is a partial cross-sectional view taken along the axial direction along line XIII-XIII shown in FIG.
引出線位置決め装置１００は、載置台および内側位置決め部材１１０に加えて、図５に示す外側位置決め部材１２０を有する。 The leader line positioning device 100 includes an outer positioning member 120 shown in FIG. 5 in addition to the mounting table and the inner positioning member 110.
外側位置決め部材１２０は、引出線２３１の位置決めの前段階において、ステータ２の径方向外側に配置される。外側位置決め部材１２０は、内側位置決め部材１１０と同数の、例えば４個が設けられる。４個の外側位置決め部材１２０は、周方向に所定間隔で並べて配置される。外側位置決め部材１２０は、移動機構（図示略）によって、引出線２３１に対して接近、離隔する方向への移動が可能である。 The outer positioning member 120 is arranged on the outer side in the radial direction of the stator 2 at the stage before positioning of the lead wire 231. For example, four outer positioning members 120 are provided in the same number as the inner positioning members 110. The four outer positioning members 120 are arranged side by side at a predetermined interval in the circumferential direction. The outer positioning member 120 can be moved in a direction approaching and separating from the lead wire 231 by a moving mechanism (not shown).
４個の外側位置決め部材１２０は各々、３個の凹部１２１を個別に有する。凹部１２１は、外側位置決め部材１２０の、引出線２３１との対向する領域に設けられ、軸方向と交差する方向に沿って引出線２３１から離れる方向に窪む。凹部１２１は、引出線２３１を受け入れ可能な形状、大きさを有する。 Each of the four outer positioning members 120 has three recesses 121 individually. The recessed part 121 is provided in the area | region which opposes the leader line 231 of the outer side positioning member 120, and is depressed in the direction away from the leader line 231 along the direction which cross | intersects an axial direction. The recess 121 has a shape and size that can receive the lead wire 231.
凹部１２１は、引出線２３１の中心軸ＣＬに対する反対側から、引出線２３１に接触可能である。外側位置決め部材１２０は、３個の凹部１２１を有するので、単一で３本の引出線２３１に、引出線２３１の中心軸ＣＬに対する反対側から接触する。単一の外側位置決め部材１２０に設けられた３個の凹部１２１によって、軸方向と交差する方向に関して、３本の引出線２３１の間隔、位置関係が明確に規定される。この構成によれば、部品点数の低減を図ることができる。また、外側位置決め部材１２０の配置に係る作業性を向上させることが可能である。 The recess 121 can contact the lead wire 231 from the opposite side of the lead wire 231 with respect to the central axis CL. Since the outer positioning member 120 has the three recesses 121, the outer positioning member 120 comes into contact with the three lead wires 231 from the opposite side of the lead wire 231 with respect to the central axis CL. The three recesses 121 provided in the single outer positioning member 120 clearly define the interval and positional relationship of the three lead lines 231 in the direction intersecting the axial direction. According to this configuration, the number of parts can be reduced. In addition, the workability related to the arrangement of the outer positioning member 120 can be improved.
外側位置決め部材１２０は、図１１に示すように、径方向外側位置決め部材１２０Ａと、周方向外側位置決め部材１２０Ｂと、を含む。径方向外側位置決め部材１２０Ａおよび周方向外側位置決め部材１２０Ｂは、互いが軸方向に並べて配置される。径方向外側位置決め部材１２０Ａおよび周方向外側位置決め部材１２０Ｂは各々、軸方向と交差する方向に関して、同じ位置に凹部１２１Ａ、１２１Ｂを有する。凹部１２１は、凹部１２１Ａおよび凹部１２１Ｂを含む。 As shown in FIG. 11, the outer positioning member 120 includes a radial outer positioning member 120A and a circumferential outer positioning member 120B. The radially outer positioning member 120A and the circumferential outer positioning member 120B are arranged side by side in the axial direction. Each of the radially outer positioning member 120A and the circumferential outer positioning member 120B has recesses 121A and 121B at the same position in the direction intersecting the axial direction. The recess 121 includes a recess 121A and a recess 121B.
径方向外側位置決め部材１２０Ａは、１個の凹部１２１Ａを有する。凹部１２１Ａは、周方向外側位置決め部材１２０Ｂの凹部１２１Ｂよりも緩やかな曲面の壁面、例えば円弧形状の壁面を有する。この形状の凹部１２１Ａによって、径方向外側位置決め部材１２０Ａは、引出線２３１の径方向の位置決めを行う。 The radially outer positioning member 120A has one recess 121A. The recess 121A has a curved wall surface that is gentler than the recess 121B of the outer circumferential positioning member 120B, for example, an arc-shaped wall surface. The radially outer positioning member 120A positions the leader line 231 in the radial direction by the concave portion 121A having this shape.
周方向外側位置決め部材１２０Ｂは、径方向外側位置決め部材１２０Ａの軸方向上面に接触させて、配置される。周方向外側位置決め部材１２０Ｂは、３個の凹部１２１Ｂを有する。凹部１２１Ｂは、径方向外側位置決め部材１２０Ａの凹部１２１Ａよりも急峻な曲面の壁面、例えばＶ字形状の壁面を有する。この形状の凹部１２１Ｂによって、周方向外側位置決め部材１２０Ｂは、引出線２３１の周方向の位置決めを行う。 The circumferential outer positioning member 120B is disposed in contact with the axially upper surface of the radial outer positioning member 120A. The circumferential direction outer positioning member 120B has three recesses 121B. The recess 121B has a curved wall surface that is steeper than the recess 121A of the radially outer positioning member 120A, for example, a V-shaped wall surface. The circumferentially outer positioning member 120B positions the leader line 231 in the circumferential direction by the concave portion 121B having this shape.
外側位置決め部材１２０は、凹部１２１Ａ、１２１Ｂによって、径方向および周方向において、引出線２３１の位置決めを行う。径方向外側位置決め部材１２０Ａと周方向外側位置決め部材１２０Ｂとを組み合わせることで、引出線２３１を適正な位置に位置決めすることが可能である。 The outer positioning member 120 positions the lead wire 231 in the radial direction and the circumferential direction by the recesses 121A and 121B. By combining the radially outer positioning member 120A and the circumferential outer positioning member 120B, the lead wire 231 can be positioned at an appropriate position.
引出線２３１の位置決め工程において、外側位置決め部材１２０は、図１２に示すように、ステータ２の径方向外側から、中心軸ＣＬ側に向けて、引出線２３１に接近する。そして、外側位置決め部材１２０は、３個の凹部１２１が各々、引出線２３１の中心軸ＣＬに対する反対側から、３本の引出線２３１に接触する。これにより、１２本の引出線２３１は個別に、内側位置決め部材１１０の凹部１１１と、外側位置決め部材１２０の凹部１２１と、よって挟まれ、適正な位置に位置決めされる。したがって、引出線位置決め装置１００は、引出線２３１を所定位置に効率良く配列することができ、モータＡの製造を短時間で行うことが可能である。 In the positioning process of the lead wire 231, the outer positioning member 120 approaches the lead wire 231 from the radially outer side of the stator 2 toward the central axis CL as shown in FIG. 12. In the outer positioning member 120, the three concave portions 121 are in contact with the three lead lines 231 from the side opposite to the center axis CL of the lead line 231. As a result, the twelve lead wires 231 are individually sandwiched between the recess 111 of the inner positioning member 110 and the recess 121 of the outer positioning member 120 and are positioned at appropriate positions. Therefore, the leader line positioning device 100 can efficiently arrange the leader lines 231 at predetermined positions, and the motor A can be manufactured in a short time.
そして、内側位置決め部材１１０は、単一で複数の引出線２３１に、引出線２３１の中心軸ＣＬ側から接触し、外側位置決め部材１２０は、単一で複数の引出線２３１に、引出線２３１の中心軸ＣＬに対する反対側から接触し、それら各々の引出線２３１の数が同じ３本である。この構成によれば、内側位置決め部材１１０および外側位置決め部材１２０で引出線２３１を挟む際、引出線２３１の位置ずれの発生を抑制することが可能である。 The inner positioning member 110 is in contact with a single lead wire 231 from the center axis CL side of the lead wire 231, and the outer positioning member 120 is a single lead wire 231 with a plurality of lead wires 231. Contact is made from the opposite side to the central axis CL, and the number of each of the leader lines 231 is three. According to this configuration, when the leader line 231 is sandwiched between the inner positioning member 110 and the outer positioning member 120, it is possible to suppress the occurrence of positional deviation of the leader line 231.
引出線２３１の位置決めが完了すると、引出線２３１に対して、図１３に示すように、内側位置決め部材１１０および外側位置決め部材１２０が配置される。内側位置決め部材１１０と、外側位置決め部材１２０と、は軸方向の異なる高さに配置される。 When the positioning of the leader line 231 is completed, as shown in FIG. 13, the inner positioning member 110 and the outer positioning member 120 are arranged with respect to the leader line 231. The inner positioning member 110 and the outer positioning member 120 are disposed at different heights in the axial direction.
この構成によれば、周方向内側位置決め部材１１０Ｂの凹部１１１Ｂと、周方向外側位置決め部材１２０Ｂの凹部１２１Ｂと、の窪みの奥行きを長くすることができる。これにより、引出線２３１の位置決め精度を向上させることが可能である。そして、凹部１１１Ｂ、１２１Ｂの窪みの奥行きが比較的長い構成は、位置決め前の引出線２３１が所定位置から比較的大きくずれている場合でも、引出線２３１の所定位置への移動が容易になる。また、この構成によれば、内側位置決め部材１１０と、外側位置決め部材１２０と、の軸方向と交差する方向における接触を回避することができる。これにより、内側位置決め部材１１０および外側位置決め部材１２０を移動させる機構が配置し易くなる。 According to this configuration, the depth of the recesses of the recess 111B of the circumferential inner positioning member 110B and the recess 121B of the circumferential outer positioning member 120B can be increased. Thereby, the positioning accuracy of the leader line 231 can be improved. And the structure with the comparatively long depth of the hollow of recessed part 111B, 121B becomes easy to move the leader line 231 to a predetermined position, even when the leader line 231 before positioning has shifted | deviated comparatively largely from the predetermined position. Moreover, according to this structure, the contact in the direction which cross | intersects the axial direction of the inner side positioning member 110 and the outer side positioning member 120 can be avoided. Thereby, it becomes easy to arrange a mechanism for moving the inner positioning member 110 and the outer positioning member 120.
特に、本実施形態では、ステータ２に、隣接する引出線２３１同士の比較的大きな隙間である第１隙間Ｌ１を設けているので、図９に示すように、引出線２３１の位置決めを行うための一対の挿入部材１３０を第１隙間Ｌ１に径方向外側から中心軸ＣＬに向かって挿入することが容易となる。 In particular, in the present embodiment, the stator 2 is provided with the first gap L1 which is a relatively large gap between the adjacent leader lines 231. Therefore, as shown in FIG. 9, the leader line 231 is positioned. It becomes easy to insert the pair of insertion members 130 into the first gap L1 from the radially outer side toward the central axis CL.
また、本実施形態では、第１隙間Ｌ１を２つ設けている。これにより、全ての引出線２３１を径方向内側から位置決めすることを、一対の挿入部材１３０からなる治具を２つ用いることで対応できるので、治具を簡易な構成とすることができる。なお、このような効果は、第１隙間Ｌ１の数を３つ、または４つとした場合も同様である。 In the present embodiment, two first gaps L1 are provided. Thereby, positioning all the leader lines 231 from the inner side in the radial direction can be dealt with by using two jigs made of the pair of insertion members 130, so that the jig can have a simple configuration. Such an effect is the same when the number of the first gaps L1 is three or four.
また、本実施形態では、２つの第１隙間Ｌ１は、中心軸ＣＬに対して点対称に配置される。これにより、一対の挿入部材１３０からなる治具を各々の第１隙間Ｌ１に挿入して位置決めを行う引出線２３１は、等分の領域における引出線であるので、２つの治具を同様の構造とすることができる。すなわち、治具の種類を削減できる。なお、このような効果は、第１隙間Ｌ１が３つ、または４つの場合でも、そのうちの２つは中心軸ＣＬに対して点対称に配置されていれば、同様である。 In the present embodiment, the two first gaps L1 are arranged point-symmetrically with respect to the central axis CL. Thereby, since the leader line 231 for positioning by inserting a jig composed of the pair of insertion members 130 into each first gap L1 is a leader line in an equal area, the two jigs have the same structure. It can be. That is, the types of jigs can be reduced. Such an effect is the same even if the number of first gaps L1 is three or four as long as two of them are arranged point-symmetrically with respect to the central axis CL.
また、本実施形態では、１２本である引出線２３１の本数は、ステータ２に含まれるコイル２３の個数１２個と同じである。これにより、隣接する引出線２３１の間に形成される各隙間の周方向幅は小さくなるので、第１隙間Ｌ１により比較的大きな隙間を設けることがより有効となる。 Further, in the present embodiment, the number of 12 lead wires 231 is the same as the number 12 of the coils 23 included in the stator 2. Thereby, since the circumferential width of each gap formed between the adjacent leader lines 231 is reduced, it is more effective to provide a relatively large gap by the first gap L1.
また、本実施形態では、引出線２３１の第２直線部２３１Ｂは、図２に示すように、環状であるステータ２の略内周側縁より軸方向に引き出される。すなわち、引出線２３１は、ステータ２の内径側より引き出される。これにより、ステータ２の内径側の円周長、すなわち各引出線２３１を引き出した位置を含む同一円の円周長は、ステータ２の外形側の円周長よりも小さくなる。そのため、隣接する引出線２３１の隙間を確保しにくくなるので、第１隙間Ｌ１により比較的大きな隙間を設けることがより有効となる。 Moreover, in this embodiment, the 2nd linear part 231B of the leader line 231 is pulled out to the axial direction from the substantially inner peripheral side edge of the stator 2 which is cyclic | annular, as shown in FIG. That is, the lead wire 231 is drawn from the inner diameter side of the stator 2. Thereby, the circumferential length on the inner diameter side of the stator 2, that is, the circumferential length of the same circle including the position where each lead wire 231 is pulled out becomes smaller than the circumferential length on the outer side of the stator 2. For this reason, it is difficult to secure a gap between the adjacent leader lines 231. Therefore, it is more effective to provide a relatively large gap by the first gap L1.
＜４．引出線支持部材＞
次に、引出線支持部材５の構成について詳細に説明する。引出線支持部材５は、先述したように、ステータ２の軸方向上側に固定される部材である。図１４は、引出線支持部材５とステータ２を示す斜視図である。
<4. Leader support member>
Next, the configuration of the lead wire support member 5 will be described in detail. The lead wire support member 5 is a member fixed to the upper side in the axial direction of the stator 2 as described above. FIG. 14 is a perspective view showing the lead wire support member 5 and the stator 2.
図１４に示すように、引出線支持部材５は、中心軸ＣＬを中心とする円環状の部材である。引出線支持部材５は、円形の開口部５０を有する。開口部５０は、径方向の略中央部に設けられる。引出線支持部材５は、複数の保持部５１と、複数の脚部５２と、を有する。 As shown in FIG. 14, the lead wire support member 5 is an annular member centered on the central axis CL. The lead wire support member 5 has a circular opening 50. The opening 50 is provided at a substantially central portion in the radial direction. The lead wire support member 5 has a plurality of holding portions 51 and a plurality of leg portions 52.
保持部５１は、開口部５０の円周に沿って設けられる。保持部５１は、引出線２３１と同数、すなわち１２個が所定の位置に配置される。保持部５１は、円筒を軸方向に沿って割った形状である。保持部５１は、軸方向に延びる溝部である収容部５１Ａを有する。なお、保持部５１は、完全な円筒で構成してもよい。保持部５１は、複数の引出線２３１各々を個別に収容部５１Ａに収容して支持する。 The holding part 51 is provided along the circumference of the opening 50. The same number of holding portions 51 as the leader lines 231, that is, 12 holding portions 51 are arranged at predetermined positions. The holding | maintenance part 51 is the shape which divided the cylinder along the axial direction. The holding part 51 has an accommodating part 51A which is a groove part extending in the axial direction. Note that the holding unit 51 may be formed of a complete cylinder. The holding part 51 individually accommodates and supports each of the plurality of lead wires 231 in the accommodating part 51A.
脚部５２は、複数が引出線支持部材５の下面外周部に設けられる。脚部５２は、軸方向下側に向かって延びる。脚部５２は、インシュレータ２２Ａの上部外周部に設けられた溝部２２Ａ１に嵌合する形状、大きさを有する。溝部２２Ａ１は、軸方向に延びる。 A plurality of leg portions 52 are provided on the outer peripheral portion of the lower surface of the leader line support member 5. The leg portion 52 extends downward in the axial direction. The leg portion 52 has a shape and size that fits into a groove portion 22A1 provided on the upper outer peripheral portion of the insulator 22A. The groove 22A1 extends in the axial direction.
引出線支持部材５はステータ２に次のような工程で固定される。引出線支持部材５をステータ２に固定する前に、あらかじめ図１２に示したように引出線位置決め装置１００によって引出線２３１の位置決めを行った状態とする。そして、その状態で、引出線支持部材５を軸方向上側からステータ２に接近させることで固定する。このとき、各引出線２３１の第２直線部２３１Ｂを各収容部５１Ａに収容し、脚部５２を溝部２２Ａ１に嵌合させる。引出線支持部材５を固定した後、挿入部材１３０および外側位置決め部材１２０をステータ２から取り外す。 The lead wire support member 5 is fixed to the stator 2 by the following process. Before the leader line supporting member 5 is fixed to the stator 2, the leader line 231 is positioned by the leader line positioning device 100 in advance as shown in FIG. 12. In this state, the lead wire support member 5 is fixed by approaching the stator 2 from the upper side in the axial direction. At this time, the second straight portion 231B of each leader line 231 is accommodated in each accommodating portion 51A, and the leg portion 52 is fitted into the groove portion 22A1. After the leader line support member 5 is fixed, the insertion member 130 and the outer positioning member 120 are removed from the stator 2.

One of the third gaps L3 faces the first gap L1 corresponding to the angle θ1 in the stator 2 shown in FIG. 2 in the axial direction, and the other faces the first gap L1 corresponding to the angle θ2 in the axial direction. That is, the two third gaps L3 have different circumferential widths.
周方向に隣接する保持部５１の間に形成される隙間のうち、第３隙間Ｌ３以外の第４隙間Ｌ４は、図２で示すステータ２における角度θ３およびθ４に対応する第２隙間Ｌ２と軸方向に対向する。すなわち、第４隙間Ｌ４は、第３隙間Ｌ３よりも周方向幅が小さい。 Among the gaps formed between the holding portions 51 adjacent to each other in the circumferential direction, the fourth gap L4 other than the third gap L3 is the axis of the second gap L2 corresponding to the angles θ3 and θ4 in the stator 2 shown in FIG.

このような構成によれば、ステータ２において治具を容易に第１隙間Ｌ１に挿入することで引出線２３１を位置決めした上で、引出線支持部材５をステータ２に固定できるので、引出線支持部材５の組み付けが容易となる。なお、第３隙間Ｌ３、および第４隙間Ｌ４の個数は、複数に限らず、１つでもよい。 According to such a configuration, since the lead wire 231 can be positioned by positioning the lead wire 231 by easily inserting a jig into the first gap L1 in the stator 2, the lead wire support can be performed. Assembling of the member 5 becomes easy. The number of the third gap L3 and the fourth gap L4 is not limited to a plurality, and may be one.

脚部５２は、第２隙間Ｌ２と径方向に重なって位置する。
That is, the lead wire support member 5 has a plurality of leg portions 52 that are spaced apart in the circumferential direction and extend in the axial direction toward the stator 2.
The leg portion 52 is positioned so as to overlap the second gap L2 in the radial direction.
これにより、脚部５２は、第１隙間Ｌ１と径方向に重なる位置に配置されないので、第１隙間Ｌ１に治具を挿入して引出線２３１を位置決めした状態で引出線支持部材５をステータ２に固定する際に、脚部５２が治具と干渉することを回避できる。 Thereby, since the leg part 52 is not arrange | positioned in the position which overlaps with the 1st clearance gap L1 in a radial direction, the leader line support member 5 is made into the stator 2 in the state which inserted the jig | tool into the 1st clearance gap L1 and positioned the leader line 231. It is possible to avoid the leg 52 from interfering with the jig when fixed to the jig.

第１分割コア群８００１の周方向一端部と第２分割コア群８００２の周方向一端部とは、第１接続部分ＣＮ１１で接続される。第１分割コア群８００１の周方向他端部と第２分割コア群８００２の周方向他端部とは、第２接続部分ＣＮ１２で接続される。以下、第１分割コア群８００１および第２分割コア群８００２のそれぞれにおいて、第１接続部分ＣＮ１１に近づく周方向を「周方向一方側」と称し、第２接続部分ＣＮ１２に近づく周方向を「周方向他方側」と称す。図１９、図２０では、「周方向一方側」をθａで示し、「周方向他方側」をθｂで示す。 One end portion in the circumferential direction of the first divided core group 8001 and one end portion in the circumferential direction of the second divided core group 8002 are connected by the first connection portion CN11. The other circumferential end of the first divided core group 8001 and the other circumferential end of the second divided core group 8002 are connected by the second connection portion CN12. Hereinafter, in each of the first divided core group 8001 and the second divided core group 8002, the circumferential direction approaching the first connection portion CN11 is referred to as “circumferential one side”, and the circumferential direction approaching the second connection portion CN12 is referred to as “circumference”. It is referred to as “direction other side”. 19 and 20, “circumferential one side” is indicated by θa, and “circumferential other side” is indicated by θb.
第１分割コア群８００１において、分割コア部８０Ａの周方向一方側端部から下側に引き出される渡り線２３２Ａは、分割コア部８０Ｂ、８０Ｃの下面を通って、分割コア部８０Ｄの周方向他方側端部に引き回される。分割コア部８０Ｂの周方向一方側端部から下側に引き出される渡り線２３２Ａは、分割コア部８０Ｃ、８０Ｄの下面を通って、分割コア部８０Ｅの周方向他方側端部に引き回される。分割コア部８０Ｃの周方向一方側端部から下側に引き出される渡り線２３２Ａは、分割コア部８０Ｄ、８０Ｅの下面を通って、分割コア部８０Ｆの周方向他方側端部に引き回される。 In the first divided core group 8001, the crossover wire 232A drawn downward from one circumferential end of the divided core portion 80A passes through the lower surfaces of the divided core portions 80B and 80C, and the other circumferential direction of the divided core portion 80D. It is routed to the side edge. The connecting wire 232A drawn downward from one end portion in the circumferential direction of the split core portion 80B passes through the lower surfaces of the split core portions 80C and 80D and is routed to the other end portion in the circumferential direction of the split core portion 80E. . The connecting wire 232A drawn downward from the one end portion in the circumferential direction of the split core portion 80C passes through the lower surfaces of the split core portions 80D and 80E and is routed to the other end portion in the circumferential direction of the split core portion 80F. .
第２分割コア群８００２において、分割コア部８０Ｇの周方向他方側端部から下側に引き出される渡り線２３２Ｂは、分割コア部８０Ｈ、８０Ｉの下面を通って、分割コア部８０Ｊの周方向一方側端部に引き回される。分割コア部８０Ｈの周方向他方側端部から下側に引き出される渡り線２３２Ｂは、分割コア部８０Ｉ、８０Ｊの下面を通って、分割コア部８０Ｋの周方向一方側端部に引き回される。分割コア部８０Ｉの周方向他方側端部から下側に引き出される渡り線２３２Ｂは、分割コア部８０Ｊ、８０Ｋの下面を通って、分割コア部８０Ｌの周方向一方側端部に引き回される。 In the second divided core group 8002, the crossover wire 232B drawn downward from the other end portion in the circumferential direction of the divided core portion 80G passes through the lower surfaces of the divided core portions 80H and 80I, and one of the divided core portions 80J in the circumferential direction. It is routed to the side edge. The connecting wire 232B drawn downward from the other end portion in the circumferential direction of the split core portion 80H passes through the lower surfaces of the split core portions 80I and 80J and is routed to the one end portion in the circumferential direction of the split core portion 80K. . The connecting wire 232B drawn downward from the other end portion in the circumferential direction of the split core portion 80I passes through the lower surfaces of the split core portions 80J and 80K and is routed to the one end portion in the circumferential direction of the split core portion 80L. .
本変形例では、このような渡り線２３２Ａ、２３２Ｂの引き回しにより、渡り線２３２Ｂは、渡り線２３２Ａより長さが短い。 In this modification, the connecting wire 232B is shorter in length than the connecting wire 232A due to the routing of the connecting wires 232A and 232B.
また、ステータ８の上面側においては、隣接する分割コア部８０Ｉと８０Ｊにおいて、分割コア部８０Ｉの周方向一方側から引出線２３１が引き出されると共に、分割コア部８０Ｊの周方向他方側から引出線２３１が引き出される。また、隣接する分割コア部８０Ｃと８０Ｄにおいて、分割コア部８０Ｃの周方向他方側から引出線２３１が引き出されると共に、分割コア部８０Ｄの周方向一方側から引出線２３１が引き出される。 Further, on the upper surface side of the stator 8, in the adjacent divided core portions 80I and 80J, the leader line 231 is drawn from one circumferential side of the divided core portion 80I, and the leader line is drawn from the other circumferential side of the divided core portion 80J. 231 is pulled out. In the adjacent split core portions 80C and 80D, the lead wire 231 is drawn from the other circumferential side of the split core portion 80C, and the lead wire 231 is drawn from one circumferential side of the split core portion 80D.
これにより、分割コア部８０Ｉと８０Ｊから引き出される引出線２３１の間に形成される隙間の周方向幅は最大となり、分割コア部８０Ｃと８０Ｄから引き出される引出線２３１の間に形成される隙間の周方向幅は最小となる。従って、分割コア部８０Ｉと８０Ｊから引き出される引出線２３１の間に形成される隙間が第１隙間Ｌ１となり、分割コア部８０Ｃと８０Ｄから引き出される引出線２３１の間に形成される隙間を含んだ第１隙間Ｌ１以外の隙間が第２隙間Ｌ２となる。すなわち、第１隙間Ｌ１は１つのみとなる。 As a result, the circumferential width of the gap formed between the lead wires 231 drawn from the split core portions 80I and 80J is maximized, and the gap formed between the lead wires 231 drawn from the split core portions 80C and 80D is maximized. The circumferential width is minimized. Therefore, the gap formed between the lead lines 231 drawn from the split core portions 80I and 80J becomes the first gap L1, and includes the gap formed between the lead lines 231 drawn from the split core portions 80C and 80D. A gap other than the first gap L1 becomes the second gap L2. That is, there is only one first gap L1.
このような変形例によっても、引出線の間隔が等間隔であることによる不都合を回避することができる。 Such a modification can also avoid the inconvenience caused by the equal intervals between the leader lines.
