Abstract:
1. A method of forming a weld joint of a stator, the method comprising: removing a portion of an insulator from each of a first core of a first magnet wire and a second core of a second magnet wire so that the first magnet wire has a first heat affectable zone and a first insulator portion adjacent the first heat affectable zone, and the second magnet wire has a second heat affectable zone and a second insulator portion adjacent the second heat affectable zone; wherein the first insulator portion includes the insulator disposed on the first core, and the second insulator portion includes the insulator disposed on the second core; wherein the first heat affectable zone has a first distal end spaced apart from the first insulator portion, and the second heat affectable zone has a second distal end spaced apart from the second insulator portion; and welding together only the first distal end and the second distal end to thereby form the weld joint, wherein welding does not transfer heat to the first insulator portion and the second insulator portion sufficient to burn the insulator.
