Abstract
A multi-phase electric machine having plurality of windings are mounted on the stator core that define a plurality of phases wherein, for each phase, the windings include at least two parallel windings, each winding comprising a pair of continuous wires. For each pole, the parallel windings fill one or more central slots and two outer slots. Each winding fills each central slot twice the number of times that the winding fills each outer slot to thereby define a slot fill ratio of 2:1 between central slots and outer slots and wherein each wire of the wire pair forming a winding fills the slots in a ratio that differs from the slot fill ratio. Each of the parallel windings includes a phase shift end loop that shift the windings from one outer slot to the other outer slot.
