Abstract
An electric machine for a vehicle includes a stator having slots and a yolk region defining a plurality of channels extending between the opposing end faces of the stator. Windings extend through the slots and have end windings adjacent to the end faces. A rotor is disposed within the stator. The electric machine also includes first and second annular covers each defining a cavity having a plurality of walls partitioning the cavity into a plurality of cooling chambers that are circumferentially isolated from each other. Each of the covers is attached to one of the end faces such that a corresponding one of the end windings is disposed within one of the cavities, and such that each of the channels is in direct fluid communication with a corresponding one of the cooling chambers of the first cover and with a corresponding one of the cooling chambers of the second cover.
