PROBLEM TO BE SOLVED: To narrow the space between a salient pole forming the magnetic body and a magnet and to reduce the height dimension of the magnet by providing the constitution, wherein metal is exposed at the facing surface of the salient pole of a stator core with the drive magnet. SOLUTION: Mutual magnetic action occurs between a salient pole and a magnet 9 by applying a specified drive current to a coil 2, and a motor is rotated. The insulating layer of the facing surface of the salient pole 11 with the magnet 9 is removed, and the metal surface forming a core 1 is exposed. Therefore, a gap (d) of the magnet 9 with the salient pole 11 can be made as narrow as possible. As a result, the magnetism-collecting force between the salient pole and the magnet can be enhanced, and the mutual magnetic action can be effectively operated. Therefore, the large drive force can be generated by the small magnet 9. |
