STEPPING MOTOR, TIMEPIECE MOVEMENT, TIMEPIECE, AND MANUFACTURING METHOD OF STEPPING MOTOR |
| 摘要 |
There is provided a stepping motor including a stator that is integrally molded by using a Fe—Ni alloy plate through machining, that has a rotor accommodating through-hole, and in which a magnetic path is disposed around the rotor accommodating through-hole, a rotor that is rotatably arranged inside the rotor accommodating through-hole, and a coil that is disposed in the stator. A Cr-diffusion region having a molten-solidified portion of Cr is formed in a portion of the magnetic path. |
