Patent ID: 6951054

Claim:
A manufacturing method of a coil member of a rotary electric machine including a winding step of forming a first straight portion, a first turning portion, a second straight portion, and a second turning portion in at least one wire on a turning base surface, the winding step comprising: a step of setting a prescribed length L and a prescribed pitch P; a first wire feeding step for advancing the wire by the prescribed length L on the turning base surface alone a wire supply line positioned on a first plane crossing the turning base surface; a first turning step, after the first wire feeding step, for turning a portion of the wire from the first plane to a second plane parallel to the first plane on the turning base surface to thereby form the first turning portion and the first straight portion; a first pushing step, after the first turning step, for pushing the first straight portion by the prescribed pitch P so that the first straight portion goes away from the turning base surface; a second wire feeding step, after the first pushing step, for advancing the wire by the prescribed length L on the turning base surface along the wire supply line; a second turning step, after the second wire feeding step, for turning a portion of the wire from the first plane to the second plane on the turning base surface in the same direction as the wire was turned in the first turning step, to thereby form the second turning portion and the second straight portion; and a second pushing step, after the second turning step, for pushing the second straight portion by the prescribed pitch P so that the second straight portion goes away from the turning base surface.
