  • Publication number: 20220294297
    Abstract: When manufacturing a stator coil by assembling coil constituent members inserted into a plurality of axial slots formed in a cylindrical stator core of an AC power generator, respective end portions of the coil constituent members inserted into the respective slots and mutually arranged in a circumferential direction, which project on at least one end surface side of the stator core, are formed to be along the circumferential direction toward a mutually approaching direction, the end portions are formed to be shifted to each other in a radial direction, and end portions of the coil constituent members mutually arranged in the circumferential direction, which are shifted to each other in the radial direction, are overlapped with each other and joined. This makes it possible to compactify the stator coil, simplify a coil shape, and suppress stress caused by thermal contraction after welding.
