Patent ID: 7911107

Claim:
A multiphase electric motor comprising: a rotor having rotor pole groups, in which N-poles and S-poles are alternately arranged in a circumferential direction of the rotor; a stator opposed to the rotor via an air gap provided between the rotor and the stator, the stator having an N number (N is a positive integer) of stator pole groups associated to individual phases of the motor and respectively arranged in an axial direction of the motor, each of the stator pole groups being arranged in a circumferential direction of the stator, corresponding stator poles of different individual phases being arranged to be offset from each other in the circumferential direction of the stator by a certain electric angle; and a 2N number of substantially looped windings arranged between the stator pole groups for the individual phases and at ends in an axial direction of the rotor, wherein the rotor pole groups are arranged opposed to the stator pole groups for the individual phases.
