PURPOSE:To obtain a rotary electric machine capable of setting a cogging force substantially to the prescribed low torque even if the magnetized state of a field is irregular by providing a projection on a salient pole. CONSTITUTION:The salient poles 22a-22c of an armature core 22 are opposed through the prescribed gap to the magnetized inner surface of a field 1. Projections 22a1-22c1 are respectively provided at the positions opposed to the field 1 of the poles 22a-22c. The projectons 22a1-22c1 are provided at the positions displaced in the circumferential direction at 360 deg./number of field poles in grooves 3a-3c for a winding. Thus, a cogging force can be reduced entirely. |
