する。[Detailed Description of the Invention] The present invention relates to a rotating electric machine, such as a motor or a generator, in which movement of crossover wires between coils is improved.
マグネツトを回転部分とし、アマチユアを固定

ものである。 2. Description of the Related Art There is a conventional electric motor having a structure shown in FIGS. 1 and 2, in which a magnet is a rotating part and an armature is a fixed part. This is attached to a base 1 and has a 9-pole core 2 and a 3-phase coil 3.
The rotating magnetic field generated at the magnetic poles of the core 2 causes the outer peripheral magnet 4 to rotate, and this rotation is extracted from the output shaft 6 via the housing 5.
そして、この場合のコイル3への巻線は、第2
図に示すようにコア2の磁極21−24−27に
巻かれる第1相の線a−a′と、磁極22−25−
28に巻かれる第2相の線b−b′と、磁極23−
26−29に巻かれる第3相の線c−c′とで成

の磁極を渡つている。 In this case, the winding to the coil 3 is the second
As shown in the figure, the first phase wire a-a' wound around the magnetic pole 2 1 -2 4 -2 7 of the core 2 and the magnetic pole 2 2 -2 5 -
The second phase wire b-b' wound around 2 8 and the magnetic pole 2 3 -
The third phase wire c-c' is wound around 26-29 , and each of the wires a-a', b-b', and c-c' crosses two magnetic poles.
ところが、この磁極を渡る渡り線は電動機の回

取り付けて、これによつて渡り線がコア2の内周
にまで移動しないようにしている。 However, the crossover wire that crosses the magnetic poles may move unnecessarily when the motor rotates, causing problems such as hitting the shaft guide portion 5a of the housing 5 and causing a short circuit. In order to control this, conventionally, a ring member 7 made of an insulator is attached to the surface of the core 2 where the crossover wire is located, thereby preventing the crossover wire from moving to the inner periphery of the core 2.
しかしながら、この従来のリング部材7による
移動規制は、その効果は良好であるが、そのリン
グ部材7の取付の作業性が芳しくなく、また特別
にリング部材を必要とするのでコスト的にも不利
であつた。 However, although this conventional movement restriction using the ring member 7 has a good effect, the workability of attaching the ring member 7 is not good, and since a special ring member is required, it is disadvantageous in terms of cost. It was hot.
本考案は斯る点に鑑み、アマチユアのコア材の
最外層部分に切起し片を形成して、これを渡り線
の移動規制部材とし、前記した問題点を解消せん
とするものである。 In view of this, the present invention aims to solve the above-mentioned problems by forming a cut and raised piece on the outermost layer of the amateur core material and using this as a movement regulating member for the crossover wire.
以下、第3図以降を参照して本考案の電動機と

塗料で覆われ、渡り線がそこに当つても短絡等が
起らないようにする。 Hereinafter, one embodiment of the electric motor of the present invention will be explained with reference to FIG. 3 and subsequent figures.
Cut and raise pieces 2a 1 arranged at equal intervals in the circumferential direction on a.
The cut and raised piece 2a1 is used as a movement regulating member for the crossover wire. The laminated plate 2a having the cut and raised pieces 2a1 is finally laminated on the outside of the core 2 and attached as a part of the core 2 as a whole using the caulking member 8. Then, an insulating coating is applied to the entire body, so that all the corners of the cut and raised pieces 2a1 are also covered with the insulating coating, so that short circuits will not occur even if the connecting wire hits there.
すなわち本考案は、アマチユアコアの片側1枚

る。 That is, in the present invention, cut and raised pieces are formed on one laminate plate on one side of the amateur core so as to be lined up at appropriate regular intervals in the circumferential direction, and the cut and raised pieces are used as movement regulating members for crossover wires. . For this reason, since a part of the core forming material is used, there is no cost disadvantage,
Further, since the attachment can be done at the time of forming the core, no special attachment work is required, and cutting and bending can also be done at the time of shaping the core material.
