Abstract: A drive unit for an electric vehicle is comprised of a motor, an inverter which supplies alternating current electric power to the motor, a speed reducer which is connected to the motor, and a cooling system which cools the motor, the inverter and the speed reducer. The speed reducer reduces a revolution speed of a mechanical output of the motor. The cooling system comprises a heat exchanger at which first refrigerant for receiving heat of at least one of the motor and the inverter receives heat of second refrigerant for receiving heat of at least one of the motor and the speed reducer.

Abstract: An integrated drive motor unit which is integrally constituted of a motor, an inverter and a reducer differential unit arranged in a row, and a frame member. The reducer differential unit is connected to an output shaft of the motor, and distributes torque of the motor to a pair of axles, one of which passes through the inverter. The frame member constitutes a part of the motor and a part of the reducer differential unit, and has a portion surrounding the axle passing through the inverter. The inverter is disposed outside the frame member.
