Abstract
A rotary electric machine stator according to the present invention includes: a frame that includes: a tube portion; and a flange portion that is disposed so as to be integrated with the tube portion so as to protrude radially outward from a first axial end of the tube portion; a stator core that is configured into an annular shape, and that is fitted together with and held inside the tube portion; coils that are mounted to the stator core; and a plurality of positioning members that are mounted to the flange portion so as to be movable radially and circumferentially around an axial center of the stator core.
Claims16
A rotary electric machine stator to be housed inside a housing, the rotary electric machine stator comprising:
- a frame that comprises:
- a tube portion;
- and
- a flange portion that is disposed so as to be integrated with said tube portion so as to protrude radially outward from a first axial end of said tube portion;
- a stator core that is configured into an annular shape, and that is fitted together with and held inside said tube portion;
- coils that are mounted to said stator core;
- and
- a plurality of positioning members provided axially adjacent to the flange portion, said plurality of positioning members respectively comprising a mounting aperture and a first positioning aperture separate from the mounting aperture,
- a plurality of second positioning apertures, each second positioning aperture of the plurality of second positioning apertures being on a first axial end of the housing,
- wherein each of said plurality of positioning members are mounted axially adjacent to said flange portion by a screw fitted through said mounting aperture so as to be movable radially and circumferentially around an axial center of said stator core to align said first positioning aperture to said second positioning aperture of the housing and position said rotary electric machine stator relative to said housing.
A manufacturing method for a rotary electric machine stator comprising:
- a frame that comprises:
- a tube portion;
- and
- a flange portion that is disposed so as to be integrated with said tube portion so as to protrude radially outward from a first axial end of said tube portion;
- a stator core that is configured into an annular shape, and that is fitted together with and held inside said tube portion;
- coils that are mounted to said stator core;
- and
- a plurality of positioning members that are mounted axially adjacent to said flange portion by a screw fitted through a mounting aperture of the plurality of positioning members so as to be movable radially and circumferentially around an axial center of said stator core to be mounted to a housing by a positioning pin through a first positioning aperture of the plurality of positioning members that is separate from the mounting aperture such that the first positioning aperture is aligned with a second positioning aperture of the housing,
- wherein:
- said plurality of positioning members are mounted to said flange portion after said stator core to which said coils have been mounted and that has been configured into said annular shape has been fitted together with and held inside said tube portion.
