PURPOSE:To simplify the manufacture and assembling of a stepping motor by integrally molding four stator yoke members with synthetic resin, and winding a coil directly on the integrally molded stator yoke. CONSTITUTION:Stator yoke members 13, 15, and stator yoke members 14, 16 are respectively butted to form the first and second stator yokes, both are displaced at stepping angle to be concentrically disposed, integrally molded with synthetic resin 17 to form a stator yoke. Then, terminal pin 18 is press-fitted to the resin 17d of the collar at the center of the stator yoke to wind and wire a stator coil 19. Then, a bearing 10a is press-fitted to the bearing housing 17d of the stator yoke, a permanent magnet rotor 7 is inserted, and a frame 20 is secured. |
