Patent ID: 7825561

Claim:
A three-phase alternating current motor, comprising: a stator including first phase stator poles carrying thereon a first phase winding selected from a U-phase winding, a V-phase winding and a W-phase winding, second phase stator poles carrying thereon a second phase winding selected from the U-phase winding, the V-phase winding and the W-phase winding and third phase stator poles in the absence of a third phase winding selected from the U-phase winding, the V-phase winding and the W-phase winding; and a rotor rotatably supported inside the stator poles of the stator; wherein the first and second phase windings are excited with excitation currents produced from three-phase alternating currents, the excitation currents allowing the stator to electromagnetically generate a three-phase alternating electromagnetic action through which the rotor is driven; the stator having three stator poles formed in an area of an electrical angle of 360°; wherein the first and second phase windings comprise the U-phase winding and the W-phase winding, respectively, wherein the first phase stator poles carry the U-phase winding so as to form a coil end portion on one axial side of the stator and the second phase stator poles carry the W-phase winding so as to form another coil end portion on the other axial side of the stator such that the U-phase winding and the W-phase winding do not intersect with each other in a circumferential direction of the stator or in an axial direction of the rotor.
