Abstract
A claw-pole type dynamo-electric machine, from which an improvement in productivity of stator winding can be expected, has such as a structure that the whole stator wiring is covered with a magnetic body, and thereby the inductance increases to pose the problem of decreasing a power factor. Disclosed is a stator core of a dynamo-electric machine in which a plurality of stator cores of respective phases are arranged independently in the direction of the rotating shaft of a rotor, the magnetic poles of the stator cores are arranged in the shape of a wave in the circumferential direction of the rotating shaft of a rotor, slots extending in the direction of the rotating shaft are formed between respective magnetic poles, and the stator winding can be arranged in a slot formed on the side of the inner end face of the magnetic pole arranged in the shape of a wave and in the axial direction of the rotating shaft.
