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.

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.

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

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

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.

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.

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.
