Abstract
A compressor device includes a coolant jacket cooperatively defined by a motor case and an outer motor housing. The coolant jacket includes a radial portion that spans about the motor case in a circumferential direction and an axial direction with respect to the axis of rotation of the motor. The coolant jacket includes an axial portion that spans in a radial direction across an axial end of the motor case. At least one of the plurality of flow passages fluidly connects the radial portion and the axial portion.
