Patent ID: 8552600

Claim:
An electric machine module comprising: an electric machine including a rotor and a stator with stator end turns; a liquid-cooled housing at least partially enclosing and supporting the electric machine, the housing further including two inner walls each adjacent to a stator end turn, the two inner walls each separately forming a portion of two separate coolant cavities; each coolant cavity positioned substantially around a stator end turn radially and substantially beside a stator end turn axially and substantially beside at least a portion of the rotor radially; and wherein each coolant cavity defines a single and separate flow path in each of the two separate coolant cavities; and a potting material in contact with the stator end turns, wherein the potting material substantially surrounds at least three sides of substantially all the stator end turns including an outer diameter of the stator end turns, an inner diameter of the stator end turns, and an axial outer end of the stator end turns, the potting material extending from the stator end turns toward the inner walls of a coolant cavity to provide a thermally conductive path from the at least three sides of substantially all the stator end turns to a coolant cavity defined by the liquid-cooled housing.
