In the figure, 2 is a yoke, 3 and 6 are field poles, and 4 and 7 are auxiliary poles. Note that the same reference numerals in the figures indicate the same or corresponding parts. Revised 1984. 7. 1. The scope of claims for utility model registration shall be amended as follows. O Utility Model Registration Claims (1) A cylindrical yoke, a field pole disposed on the inner periphery of the yoke, and adjacent to the field pole with a predetermined gap in the circumferential direction. Auxiliary poles are arranged, and an armature is rotatably mounted opposite the field poles and the auxiliary poles, and the pole arc width of the field poles is twice the pole arc width of the auxiliary poles. The electric motor made above. (2) The electric motor according to claim 1, wherein the field poles are composed of permanent magnets. (3) The electric motor according to claim 1 or 2, wherein the auxiliary pole is made of a soft iron member.

Claims

[Scope of utility model registration request]
