摘要：A cooling assembly is disclosed for use with an electric machine having ahousing, a shaft rotatably supported within the housing, a rotor operatively coupled torotate with the shaft, and a stator annularly surrounding the rotor. The cooling assembly

may have an axial passage formed along a longitudinal axis of the shaft and configured todirect cooling oil from a first end of the shaft towards a second end of the shaft oppositethe first end of the shaft. The cooling assembly may also have an angled passage fluidlyconnected to the axial passage and configured to redirect the cooling oil towards a gapbetween an outer surface of the rotor and an inner surface of the stator. The coolingassembly may further have an arcuate groove formed along the outer surface of therotor and configured to sling the cooling oil towards opposing ends of the rotor.
