Abstract:
1. An electric machine module comprising: a housing at least partially defining a machine cavity; a coolant jacket being at least partially positioned within the housing; and a plurality of coolant apertures being at least partially circumferentially disposed through a portion of the housing so that the coolant jacket is in fluid communication with the machine cavity, the plurality of coolant apertures further comprising a stator assembly positioned within the machine cavity so that the coolant jacket substantially circumscribes at least a portion of the stator assembly, the stator assembly comprising a stator core including axial faces and stator end turns extending from the stator core, and wherein at least a portion of the coolant apertures are substantially adjacent to at least a portion of the stator end turns; and wherein a first portion of the stator end turns are configured and arranged to guide at least a portion of the coolant axially inward toward at least one of the axial faces of the stator core, and a second portion of the stator end turns are configured and arranged to guide at least a portion of the coolant axially outward; and wherein the stator assembly is positioned within the machine cavity so that the first portion of stator end turns is substantially adjacent to the first group of coolant apertures and the second portion of stator end turns is substantially adjacent to the second group of coolant apertures.
