Patent ID: 7764001

Claim:
A rotating electric machine of s (s is plural) phases, comprising: a rotor including n (n is a natural number) magnetic poles, and a stator including a stator core having 2n×s teeth corresponding to two times said s phases for each of said n magnetic poles and 2n×s slots each formed between adjacent said teeth, and n×s coils wound around said 2n×s teeth, said n×s coils constituting a coil group wound in a manner shifted by just one slot per phase for each of said n magnetic poles, said 2n×s teeth including a same-phase-intermediate tooth having coils of a same phase inserted in two slots formed at both sides in a direction of a rotational shaft of said rotor, and a different-phase-intermediate tooth having coils of different phases inserted at two slots formed at both sides in the direction of the rotational shaft of said rotor, and said rotating electric machine having a difference established in magnetic resistance of a magnetic circuit formed at each of said same-phase-intermediate tooth and said different-phase-intermediate tooth when alternating current is supplied to said n×s coils such that the number of flux linkages passing through acquire balance with each other for said magnetic circuit.
