Patent ID: 8136221

Claim:
A method for manufacturing a stator coil loaded on a rotary electric machine, the stator coil being wound with a plurality of phase windings, comprising: a shaping step of shaping a plurality of shaped wire members from electrically conductive wires; an integrating step of integrating a plurality of the shaped wire members to form an integrated body; and a winding-up step of winding up the integrated body about a core member to form a wound body, the shaped wire members each having a plurality of linear portions extending parallel to each other and being juxtaposed in a longitudinal direction of the integrated body, and a plurality of turn portions for connecting the adjacent linear portions with each other alternately at one end side and at the other end side of the linear portions, and the shaped wire members each having a plurality of linear superposition portions in the longitudinal direction of the integrated body, the linear superposition portions each being formed by superposing the linear portions with each other; the wound body formed in the winding-up step having a plurality of linear stack portions in a circumferential direction of the wound body, the linear stack portions each being formed by stacking a plurality of the linear superposition portions in a radial direction, wherein the winding-up step comprises a step of performing curve forming by inserting and withdrawing preliminary alignment members into and from respective gaps formed between the linear superposition portions adjacent to each other in the integrated body such that the turn portions of the integrated body are plastically deformed into a curved shape, during conveyance of feeding the integrated body to the core member.
