Abstract
An electric motor system includes a stator and a cover. The stator has windings that are affixed to an end periphery of the stator. The cover is secured to stator and defines a channel and a plenum. The channel extends along the end periphery and is configured to direct cooling fluid about the windings. The plenum extends over at least twenty percent of an outer perimeter of the cover and is configured to direct cooling fluid into the channel.
Claims20
An electric motor system comprising:
- a stator having windings affixed to an end periphery of the stator;
- and
- a cover secured to stator and defining,
- a channel extending along the end periphery and configured to direct cooling fluid about the windings, and
- a plenum extending over at least twenty percent of an outer perimeter of the cover and configured to direct cooling fluid into the channel.
A cover for end windings that are affixed to an end periphery of an electric motor stator comprising:
- a housing defining,
- a channel that is configured to extending along the end periphery and direct cooling fluid about the end windings, and
- a plenum in fluid communication with the channel and configured to direct cooling fluid into the channel through at least two openings.
A method of cooling end windings that are affixed to an end periphery of an electric motor stator comprising:
- directing cooling fluid into a plenum;
- and
- directing cooling fluid from the plenum through at least two openings and into a channel that extends along the end periphery such that the cooling fluid is distributed to the end windings.
