Patent ID: 8269383

Claim:
An electric machine module capable of being cooled by a coolant, the electric machine module comprising: an electric machine including a stator with stator end turns; a housing enclosing the electric machine, an inner wall of the housing defining a machine cavity, the housing further comprising a coolant jacket circumscribing at least a portion of the electric machine and at least one coolant aperture being positioned substantially adjacent to at least a portion of the stator end turns, the coolant jacket capable of containing a volume of the coolant, the at least one coolant aperture being configured to disperse at least a portion of the coolant from the coolant jacket into a stator cavity; and a cover coupled to the housing and extending radially inward into the machine cavity, the cover and the stator end turns defining the stator cavity, the stator cavity being in fluid communication with the machine cavity, wherein the cover is configured and arranged to concentrate at least a portion of the coolant within the stator cavity substantially around the stator end turns when the coolant enters the machine cavity from the at least one coolant aperture.
