A stator core of rotary electric machine has a plurality of slots. The slots are fully occupied by a stator winding to provide maximum output. On the other hand, to provide reduced output, empty unused slots are located alternately along a circumferential direction. The stator winding is only accommodated in the fully occupied slots. Therefore, rotary electric machines having different performances are provided without a drastic design change of the stator core.
