Patent ID: 7155805

Claim:
A method for manufacturing a stator of a rotary electric machine comprising a stator core having a plurality of slots opening inside and a stator winding having a plurality of phase-windings, the method comprising: a step of forming from a continuous wire a plurality of circumferentially neighboring coils, each said coil having a pair of generally straight portions which are one-magnetic-pole-pitch circumferentially shifted from each other and first and second coil end portions at opposite axial ends; a step of bending each of said straight portions at the middle thereof to provide a pair of slot-accommodated portions to be accommodated in a pair of the slots which are one-magnetic-pole-pitch shifted in a circumferential direction and a shifting portion between the slot-accommodated portions; and a step of bending said shifting portion at the middle thereof so that the second coil end portion overlaps the first coil end portion of one of the coils neighboring thereto and said shifting portion forms a third coil end portion located opposite said first and second coil end portions, thereby forming one of a plurality of phase windings.
