PROBLEM TO BE SOLVED: To provide a synchronous drive motor satisfying high torque, high output, and down-sizing with higher level.SOLUTION: A synchronous drive motor includes a stator having a stator core including a plurality of teeth provided while spaced apart by slots in the circumferential direction, and a winding passing through the slots, where all of the plurality of teeth include have a portion around which the winding is wound, and a rotor having a permanent magnet, and a plurality of pole faces formed by the permanent magnet on the surface facing the stator. The plurality of teeth have tips facing the pole faces, and the tips have a larger number of pole faces than the number of the plurality of teeth, and the circumferential width smaller than those of the pole faces.SELECTED DRAWING: Figure 7 |
