Abstract
An e-machine includes a housing and a rotating group supported for rotation about an axis of rotation within the housing. The e-machine includes a stator with a plurality of end windings. The e-machine further includes a plurality of nozzles that is removably supported by the housing and spaced apart in a circumferential direction about the axis of rotation. The plurality of nozzles is directed generally radially toward the axis of rotation and toward the plurality of end windings for spraying a cooling fluid on respective ones of the plurality of end windings.
Claims20
An e-machine comprising:
- a housing;
- a rotating group supported for rotation about an axis of rotation within the housing;
- a stator disposed within the housing that is operably coupled to the rotating group, the stator including a plurality of end windings;
- a plurality of nozzles removably supported by the housing and spaced apart in a circumferential direction about the axis of rotation, the plurality of nozzles directed generally radially toward the axis of rotation and toward the plurality of end windings for spraying a cooling fluid on respective ones of the plurality of end windings.
An electric motor comprising:
- a housing;
- a rotating group supported for rotation about an axis of rotation within the housing;
- a stator disposed within the housing that is operably coupled to the rotating group, the stator including a plurality of end windings, the plurality of end windings collectively defining an imaginary end winding outer boundary that extends continuously about the axis of rotation;
- and
- a plurality of nozzles removably supported by the housing and spaced apart in a circumferential direction about the axis of rotation in a nozzle arrangement, the plurality of nozzles in the nozzle arrangement directed generally radially toward the axis of rotation, the plurality of nozzles configured for atomizing a cooling fluid and spraying the cooling fluid in a collective spray profile that covers at least part of the imaginary end winding outer boundary and onto respective ones of the plurality of end windings, the collective spray profile covering a majority of the imaginary end winding outer boundary in a circumferential direction about the axis of rotation.
A method of manufacturing an e-machine comprising:
- providing a housing;
- supporting a rotating group for rotation about an axis of rotation within the housing;
- inserting a stator within the housing, the stator including a plurality of end windings;
- and
- removably supporting a plurality of nozzles in the housing to be spaced apart in a circumferential direction about the axis of rotation, the plurality of nozzles directed generally radially toward the axis of rotation and toward the plurality of end windings for spraying a cooling fluid on respective ones of the plurality of end windings.
