Winding overhang machining method, winding overhang structure, and stator assembly

Abstract

A winding overhang machining method includes: cutting off corners of tip portions of conductors to form welding surfaces which are angled with respect to axes of the respective conductors; exerting a pushing force on each of the conductors, which have been inserted through an iron core so as to protrude out of the iron core, to form a bend in a base portion of the conductor so that the welding surfaces of two of the bent conductors to be connected together become contiguous and form a welding line; and connecting the two conductors together by performing laser welding on the welding surfaces. With this arrangement, a winding overhang structure can be obtained by processing the tip portions of the conductors with pushing forces but not drag forces.
