Abstract
An exhaust gas-driven turbine drives a compressor to charge an internal combustion engine. An integral motor is positioned on the connecting shaft to add power to the turbocharging shaft, especially at low exhaust gas volume. Cooling for this motor includes circulation of engine oil therearound and may include insulation to limit heat inflow from the turbine and may include air flow through the motor to carry away heat inflow from the turbine.
