Abstract
A switched reluctance motor includes a stator having a plurality of pairs of opposing stator pole portions which project inward in the diametrical direction and which extend in the axial direction, a rotor rotatably disposed in the stator and having a plurality of rotor pole portions which project outward in the diametrical direction and which extend in the axial direction and axis portion which is rotatably supported on a housing. A plurality of coils are wound on each of the pair of the stator pole portions and an absorbing mechanism is provided for absorbing radial vibrations of the rotor which are generated by a variation of the magnetic attracting force acting on the rotor pole portions.
