Abstract: A stator for an electric machine comprises a cylindrical core defining an inner cylindrical surface and an outer cylindrical surface with a plurality of slots formed between the inner cylindrical surface and the outer cylindrical surface. Windings are positioned on the cylindrical core. The leads of the windings include a plurality of inner leads associated with conductors in an inner layer of the slots and a plurality of outer leads associated with conductors in an outer layer of the slots. A bus bar assembly includes a plurality of inner bus bars and a plurality of outer bus bars, the plurality of inner bus bars connected to the plurality of inner leads, and the plurality of outer bus bars connected to the plurality of outer leads. The plurality of outer bus bars are positioned radially outward from the end turns of the windings and radially inward from the outer cylindrical surface.
