Abstract

PURPOSE:To obtain high torque by arranging thin nonmagnetic material between adjacent field poles and increasing the area of the field poles. CONSTITUTION:A plurality of permanent magnets 1c are fixed to a yoke 10b. This magnets 1c are formed in sector shape, are arranged so that the adjacent polarities are opposite to each other on the surface of the yoke 10b, and a thin nonmagnetic material 11 is inserted between the poles. In this manner, the area of the poles can be increased, and effective crossing magnetic fluxes which cross the winding 8b of a motor armature by the magnetic flux of the magnets 1c can be increased.
