摘要： A stator for an electric machine includes a stator core defining an axial direction, a first end, and a second end. The stator core includes a plurality of slots formed between a plurality of teeth, wherein each of the plurality of slots extend from the first end to the second end of the stator core and define a slot opening on a radially inward portion of the stator core. A plurality of conductors are positioned in each of the slots and are connected together to form a winding arrangement for the stator. A wedge is positioned in each slot of the stator core radially inward from the plurality of conductors positioned in said slot. The wedge includes a first leg positioned on one side of the slot, a second leg positioned on an opposite side of the slot, and a bridge spanning across the slot opening.

摘要： A method of forming a stator for an electric machine includes forming a first conductor and a second conductor into a plurality of bends having a first winding pitch, creating a winding layer by introducing the first conductor and the second conductor into a first pole of a stator with the second conductor being on top of the first conductor at a first end loop crossing zone. The winding pitch of the first conductor is changed to a second winding pitch and the winding pitch of the second conductor is changed to a third winding pitch. The first conductor is woven relative to the second conductor between the first pole and a second pole. The first conductor and the second conductor are introduced into the second pole of the stator with the first conductor being on top of the second conductor at a second end loop crossing zone.
