Abstract:
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.
