Patent ID: 8513840

Claim:
An electric machine module comprising: a module housing at least partially defining a machine cavity; an electric machine positioned in the machine cavity and at least partially enclosed by the module housing, the electric machine including a stator assembly including stator end turns and a rotor assembly, the stator assembly circumscribing at least a portion of the rotor assembly; and the module housing including a coolant transport network, the coolant transport network including: at least one passage in fluid communication with at least one first annulus and at least one second annulus, wherein the at least one first annulus is substantially axially adjacent to an axial end of the stator assembly and the at least one second annulus is substantially axially adjacent to an axial end of the rotor assembly, and each of the at least one first annulus and the at least one second annulus comprising a plurality of annulus apertures so that the at least one first annulus and the at least one second annulus are in fluid communication with the machine cavity.
