Patent ID: 8482169

Claim:
An electric machine module comprising: an electric machine including a rotor and a stator with stator end turns, the stator circumscribing at least a portion of the rotor; a rotor hub coupled to the rotor, the surface of the rotor hub integrally including a plurality of axial fins on both sides of the rotor hub; a through bolt; and a housing including at least two removably-coupled frame members, each of the at least two removably-coupled frame members including an inner wall at least partially defining a machine cavity and capable of partially enclosing the electric machine, an outer wall, a coolant cavity at least partially defined between the inner wall and the outer wall, the coolant cavity positioned substantially around each stator end turn radially and axially, the coolant cavity extending substantially the entire radial length of the plurality of axial fins on both axial sides of the rotor hub, and; a bolt channel formed through a portion of each of the at least two removably-coupled frame members, the bolt channel being located radially inward from an outer substantially circular periphery of the housing, the bolt channel capable of receiving at least a portion of the through bolt to couple together the at least two removably-coupled frame members.
