To reduce the cost, improve the performance and reduce the size of a motor. The stator magnetic poles 117, 118, 119, 11A, 11B, and 11C and the salient pole made of a soft magnetic material of a rotor 11E can generate an attractive force with a high magnetic flux density individually. Three-phase, full-pitch winding, concentrated winding, salient pole teeth, and soft magnetic salient pole rotor with simple motor configuration, each winding is driven by a unidirectional current, and each winding has two or more stator poles It can be used for both. As a result, the DC current drive and the configuration capable of supplying power through two paths greatly reduce the total current capacity of the power transistor, thereby reducing the size and cost of the drive device. .
