Claim 0:
1. A compressor device comprising: a compressor section with a compressor wheel; a motor section with an electric motor having a motor axial end and a motor radial face, the electric motor being received within by a motor case, the motor case including a radial portion that covers the motor radial face and an axial end that covers the motor axial end, the motor section including an outer motor housing, the motor case supported within the outer motor housing with the outer motor housing covering the radial portion of the motor case and the axial end of the motor case and a gap defined between the motor case and the outer motor housing; a shaft that extends between the compressor wheel and the motor section, the shaft configured to be driven in rotation about an axis by the electric motor to drivingly rotate the compressor wheel within the compressor section; a motor cooling system with an inlet extending through the outer motor housing, an outlet extending through the outer motor housing, and a coolant jacket defined in the gap between the motor case and the outer motor housing to jacket the motor case and the electric motor therein, the inlet configured to feed a coolant fluid to the coolant jacket, the outlet configured to receive the coolant fluid from the coolant jacket; the coolant jacket configured to direct flow of the coolant fluid from the inlet to the outlet, the coolant jacket including a plurality of flow passages configured to distribute flow of the coolant fluid about the motor case, the plurality of flow passages defining at least one diverging flow path and at least one converging flow path; and the coolant jacket including a radial portion that spans about the motor case in a circumferential direction and an axial direction with respect to the axis, the coolant jacket including an axial portion that spans in a radial direction across the an axial end of the motor case, at least one of the plurality of flow passages fluidly connecting the radial portion of the coolant jacket and the axial portion of the coolant jacket.
