A multiple phase switched reluctance motor (30). A stator assembly (32) has a plurality of inwardly salient teeth (34a-341) terminating at a central bore (36). A rotor assembly (38) is disposed for rotation in the bore and has a plurality of rotor teeth (42a-42d). The stator assembly has at least one redundant pole set for each motor phase. The rotor assembly has a corresponding proportional number of rotor teeth. The redundancy of the poles helps distribute ovalizing forces on the motor assembly. This lessens the effect of these forces and reduces motor noise produced by the assembly in response to the forces. In addition, the stator can have multiple teeth per pole and the rotor a multiple of the determined rotor teeth. The number of rotor teeth exceeds the number of stator teeth so the rotor teeth overlap the stator teeth. This improves starting torque in a desired direction of motor rotation.
