ABSTRACT:
A three-phase reluctance motor includes, a stator having a plurality of magnetic poles around which coils corresponding to three phases are wound, a rotatable rotor having a plurality of convex poles opposed to the magnetic poles of the stator, a magnet provided on the rotor for magnetizing alternately the convex poles to N- and S-polarities in a circumferential direction, and a control circuit for magnetically exciting selectively only two of the three phases to the N- and S-polarities, respectively, and for sequentially switching two phases which are to be excited, to thereby rotate drive the rotor.
