Abstract
A multiple pole, multiple phase, permanent magnet motor comprising a rotor having a plurality of permanent magnet poles, a stator having a plurality of stator slots and an equal number of stator teeth defined by adjacent stator slots, and a plurality of phase windings disposed on the stator, each phase winding including a plurality of coils having a non-uniform number of turns, such that electromagnetic poles are developed in proximity to the stator, the electromagnetic poles for each phase being distributed symmetrically about the stator, equidistant from one another, and equal in number to the number of permanent magnet rotor poles. The number of turns of each of the plurality of coils of each phase winding is selected in accordance with a predetermined sinusoidal relation.
