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.
