Abstract
Provided is an electric motor including a permanent magnet rotor and two sets of multi-phase windings serving as coil windings of a stator. The coil windings are wound around teeth by concentrated winding. The multi-phase windings of one of the two sets are wound around every other tooth by skipping one tooth in between. The multi-phase windings of another of the two sets are wound around the teeth skipped by the multi-phase windings of the one set. Adjacent coil windings of the two sets are wound in the same direction. A control unit configured to supply power to the coil windings includes control circuits independent of each other to provide one control circuit for each of the two sets of coil windings, and the control unit controls the control circuits with two sets of control signals having a phase difference of 150 degrees.
