  • Coil installation method and coil installation jig
    Patent number: 10027208
    Abstract: A coil installation method for installing a coil on a tooth of a stator core to manufacture a stator for a rotary electric machine, the coil installation method including forming the coil such that a rectangular wire is wound into a generally quadrangular shape so as to form three or more winding portions overlapping in a radial direction of the stator core and such that the winding portion positioned on an outer peripheral side in the radial direction has a larger width directed in a circumferential direction of the stator core.
    Type: Grant
    Filed: July 24, 2014
    Date of Patent: July 17, 2018
    Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHA

  • Method for manufacturing a stator for a rotating electrical machine
    Patent number: 10027209
    Abstract: A method for manufacturing a stator for a rotating electrical machine by placing coils in a stator core, wherein each of a plurality of teeth formed in a radial pattern in an inner periphery of an annular yoke portion in the stator core has tip-end parallel side surfaces formed in its tip end portion having a constant width in a circumferential direction, has intermediate tilted side surfaces continuous with the tip-end parallel side surfaces and formed in its portion whose width in the circumferential direction increases closer to an outer periphery, and has base-end parallel side surfaces continuous with the intermediate tilted side surfaces and formed in its base end portion having a constant width in the circumferential direction.

  • METHOD FOR MANUFACTURING A STATOR FOR A ROTATING ELECTRICAL MACHINE
    Publication number: 20160181895
    Abstract: A method for manufacturing a stator for a rotating electrical machine by placing a plurality of coils in a stator core, wherein each of a plurality of teeth formed in a radial pattern in an inner periphery of an annular yoke portion in the stator core has tip-end parallel side surfaces at its tip end portion having a constant width in a circumferential direction, and has base-end tilted side surfaces in its base end portion whose width in the circumferential direction increases closer to an outer periphery.
