Abstract:
A three-phase electric machine includes a stator core defining slots, a terminal associated with one of the three phases, and a neutral. A first phase of hairpin windings is disposed in the core and has first and second parallel paths that are each continuous between the terminal and the neutral. The first path includes a first hairpin having a first leg disposed in a first of the slots and a second leg disposed in a second of the slots that is five slots away from the first slot. The first path further includes a second hairpin having a first leg disposed in a third of the slots and a second leg disposed in the second slot, wherein the second slot is seven slots away from the third slot.
