Abstract: An electric machine having a stator with windings all having the same length. The stator includes a plurality of slots. A plurality of windings are mounted in the slots of the stator core and define a plurality of poles circumferentially distributed about the stator core. Each winding defines at least a first wrap and a second wrap wherein each of the first and second wraps circumscribes the stator core. Each of the first and second wraps includes a wire segment disposed in a slot in each pole. The first wrap of each winding is primarily disposed in one of the layers and the second wrap of each winding is primarily disposed in a different one of the layers. The first wrap of each winding defines a first linear length and the second wrap of each winding defines a second linear length that differs from the first linear length.

Abstract: A multi-phase electric machine having plurality of windings are mounted on the stator core and define a plurality of phases with each phase having at least two parallel windings. A standard pitch is defined between each pole of each phase, the pitch being a common circumferential spacing between corresponding slots of each pole. Each of the windings has a position change end loop at the same location, wherein the position change end loops define a non-standard pitch to thereby change the relative positions of the parallel windings in the slots. At each set of such position change end loops, the windings defining a greater pitch extend over the windings defining a lesser pitch.
