Further miniaturization is required. In particular, there is a strong demand for reducing the diameter of stepping motors, and the shape of the motor is becoming elongated.
以下、図面を参照しながら従来のステッピングモー夕の
固定子鉄心の一例について説明する。Hereinafter, an example of a stator core of a conventional stepping motor will be described with reference to the drawings.

In FIG. 4, a coil bohin 2 is attached to the magnetic pole teeth of a stator core 1, and a rotor 4 made of permanent magnets is attached to the inner diameter of two sets of stators with windings 3 through sliding bearings 5 and 6. It is held by a frame 7 and a bracket 8.

In FIG. 4, the comb-shaped magnetic pole part 1a of the stator core 1 and the disc-shaped part 1b for fixing the stator coil are formed by punching or other processing from a plate-shaped material. The stator core 1 is obtained by bending the toothed portion 1a.
発明が解決しようとする課題
しかしなから上記構成では歯部の形状か固定子鉄心の内
径の大きさに制限されてしまい、一定の長さ以」二の歯
状磁極部を作ることがむずかしい。Problems to be Solved by the Invention However, with the above configuration, it is limited by the shape of the tooth portion or the size of the inner diameter of the stator core, and it is difficult to create a tooth-shaped magnetic pole portion with a certain length or more.

の為に固定子鉄心の内径を広げると、円板部の内径が太
き《なり巻線の為のスペースが少な《なり特性を上げら
れないと言う問題があった。In order to improve the motor's 1-lux characteristic, it is necessary to increase the length and width of the comb-shaped magnetic pole part as much as possible, but if the inner diameter of the stator core is increased for this purpose, the inner diameter of the disc part becomes thicker. There was a problem in that the space for the winding was small and the characteristics could not be improved.
特に、モータ直径の小型化か要求される時は長さ方向に
制限がなくとも、モータの直径により櫛歯状磁極部の長
さが必然的に決まってしまい、モータの長さをい《ら長
くしても一定限度以上の特性の向上はむずかしかった。In particular, when miniaturization of the motor diameter is required, the length of the comb-shaped magnetic pole part is inevitably determined by the motor diameter, even if there is no restriction in the length direction. Even if the length was increased, it was difficult to improve the characteristics beyond a certain limit.
