  • Method of manufacturing stator coil
    Patent number: 8371020
    Abstract: A plurality of shaped wires, which are obtained by shaping electric wires, are assembled to form a wire assembly 47. The wire assembly 47 is then rolled around a core member 6 with aligning members 7 being inserted into spaces 472 formed between adjacent ones of straight superposed parts 471 of the wire assembly 47.
    Type: Grant
    Filed: March 11, 2009
    Date of Patent: February 12, 2013
    Assignee: Denso Corporation

  • Method of manufacturing coil for stators mounted in rotary electric machines
    Patent number: 8166628
    Abstract: In manufacturing a stator coil for rotary electric machine having phase windings, plural conductive shaped wire members are integrated mutually to form an integrated body. Each shaped wire member has plural straight portions and plural turn portions alternately connecting adjacent straight portions at each of both ends of each straight portion. The body has plural straight superposed portions each formed by mutually superposing the plural straight portions. A wound-up body has plural straight stack portions The straight portions 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 straight stack portions. The integrated body is wound about a core member together with the alignment member, with the straight portions being fitted to the alignment member to form the wound-up body.
