Patent ID: 8294325

Claim:
A stator core for a dynamo-electric machine having a rotor supported in a rotatable manner, and a stator having at least two stator cores aligned in a rotating shaft direction of the rotor, the stator core comprising: a plurality of magnetic poles of the stator core arranged in a circumferential direction of the rotating shaft of the rotor, and stator core slots formed in an axial direction of the rotating shaft between the respective magnetic poles of the plurality of magnetic poles; wherein the respective magnetic poles arranged in the circumferential direction have end faces in the axial direction of the rotating shaft formed in a shape of a wave with respect to adjacent magnetic poles in the axial direction of the rotating shaft, so that a stator winding can be arranged in the slots formed on the side of the inner end faces of the magnetic poles arranged in the shape of a wave and in the axial direction of the rotating shaft, and wherein the magnetic poles of the plurality of stator cores arranged in the circumferential direction of the rotating shaft are formed of steel sheets laminated in the axial direction of the rotating shaft.
