Abstract
A stator for a rotating electric machine includes an annular stator core and a plurality of winding groups mounted on teeth of the stator core. Each of the winding groups is either a short-pitch winding group which consists of windings wound at a pitch shorter than 180° in electrical angle or a full-pitch winding group which consists of windings wound at a pitch equal to 180° in electrical angle. The winding groups include at least one short-pitch winding group pair which consists of two short-pitch winding groups that respectively belong to two different phases and are circumferentially adjacent to each other. The two short-pitch winding groups are arranged so as not to overlap each other in a radial direction of the stator core. There are no other winding groups interposed between the two short-pitch winding groups in the circumferential direction of the stator core.
