Patent ID: 8132315

Claim:
A method of manufacturing a stator coil in which a plurality of phase windings are wound, comprising: a shaping step of shaping a plurality of shaped bodies from electric conductor wires; a combining step of combining said plurality of said shaped bodies to one another to form a combined body; and a winding step of winding said combined body around a core member to form a wound body; wherein said shaped body includes a plurality of straight portions extending in parallel to one another and aligned along a longitudinal direction of said combined body, and a plurality of turn portions each connecting adjacent ones of said straight portions at one end side and the other end side of said straight portions in an alternating manner, each of said shaped bodies including, in said longitudinal direction of said combined body, a plurality of straight overlap sections formed of said straight portions being overlapped, said wound body obtained at said winding step includes, in a circumferential direction of said wound body, a plurality of straight laminated sections formed of said plurality of said straight overlap sections laminated in a radial direction, and in said winding step, by inserting pre-orientation members respectively into consecutive ones of a plurality of clearances formed between said straight overlap sections adjacent to each other of said combined body during sending said combined body into said core member, overlap of said straight portions in said straight overlap section caught between said pre-orientation members is aligned.
