Abstract
A cooling assembly for an electric machine is disclosed. The cooling assembly may include a generally cylindrical cooling jacket for receiving a shaft, a rotor and a stator. Further, the cooling jacket jacket may be disposed in an electric machine housing. Additionally, the cooling assembly may include at least two first passages in the cooling jacket for circulating a first coolant and at least one second passage in the cooling jacket for circulating a second coolant, the second passage being disposed between the at least two first passages. Further, the cooling assembly may include a third passage on an exterior of the machine housing, the third passage extending through the housing to fluidly connect the at least two first passages and bypass the second passage.
