ABSTRACT:
A stator for a dynamoelectric machine having a primary phase winding arranged in a plurality of winding receiving slots and including at least two coil groups defining at least two predetermined primary magnetic poles. An auxiliary phase winding defining at least two auxiliary magnetic poles angularly displaced from the primary magnetic poles. The at least two predetermined magnetic poles having a polar axis. Each primary phase winding coil group is symmetrical about the polar axis. The first slot each side the axis established by the first phase winding is of a first predetermined size, three slots next adjacent each first slot are of a second predetermined size, and two slots of a third predetermined area are next adjacent to the slots of the second predetermined area. The slots of the third predetermined size are larger than the slots of the second predetermined size and the slots of the second predetermined size are larger than the slots of the first predetermined size.
