Patent ID: 8166628

Claim:
A method of manufacturing a stator coil which is wound about a stator of a rotary electric machine and provides a plurality of phase windings, the method comprises: a shaping step of shaping a plurality of shaped wire members from electrically conductive wires providing the phase windings; an integrating step of forming an integrated body by integrating the plurality of shaped wire members with each other; and a winding step of forming a wound-up body by winding the integrated body about a core member, wherein: each of the shaped wire members has a plurality of straight portions juxtaposed in the longitudinal direction of the integrated body, and a plurality of turn portions alternately connecting the straight portions, which are adjacent to each other, at one end and the other end of each of the straight portions; the integrated body has a plurality of straight superposed portions in the longitudinal direction, the plurality of straight superposed portions each being formed by mutually superposing the plurality of straight portions; the wound-up body obtained at the winding step has a plurality of straight stack portions in the circumferential direction of the wound-up body; and at the winding step, the straight portions of the integrated body are fitted to respective fitting grooves of an alignment member, the fitting grooves being formed in the alignment member at intervals each corresponding to the size of a gap between adjacent ones of the plurality of straight stack portions, the integrated body being wound about the core member together with the alignment member, with the straight portions being fitted to the alignment member to form the wound-up body.
