Claim 12:
13. A method of manufacturing a compressor device comprising: providing a compressor section of the compressor device with a compressor wheel; encasing an electric motor in a motor case of a motor section, the electric motor having a motor axial end and a motor radial face, the electric motor being received within the 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; supporting the motor case within an 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; extending a shaft 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; and defining a coolant jacket of a motor cooling system between the motor case and the outer motor housing to jacket the motor case and the electric motor therein, the motor cooling system having an inlet and an outlet that extend through the outer motor housing, 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 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.
