Patent ID: 6909216

Claim:
A motor generator, comprising: a rotor having a plurality of permanent magnets; a stator having a plurality of teeth; and two or more winding groups having a plurality of windings in each group, the windings of the winding groups are wound separately around the plurality of teeth in a mechanically and electrically mutually independent configuration, wherein the plurality of teeth are classified into first teeth and second teeth, the winding groups are classified into first winding groups and second winding groups, and a plurality of groups comprising a plurality of the first teeth wound with the windings of the first winding groups are provided in the entire stator; and windings of the first winding groups to which voltage of the same phase is applied are wound around the plurality of first teeth within the same group in the manner of that the winding direction is opposite in adjacent first teeth, different phases of voltage are applied to the adjacent plurality of groups, and the second teeth wound with windings of the second winding groups are provided between the groups.
