摘要： A drive unit for an electric vehicle is comprised of a motor (60), an inverter (50) which supplies alternating current electric power to the motor, a speed reducer (70) 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 (30) 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.

摘要： The SR motor (1) includes a stator (3) having a plurality of salient poles (3a), windings (C) wound around the plurality of salient poles (3a) and generating magnetic fields in the plurality of salient poles (3a), and a rotor (2) having another plurality of salient poles (2a), a number of the salient poles of the rotor being determined depending upon a number of the salient poles of the stator. A supply mode for supplying power from a power supply to the windings (C), a reflux mode for setting both terminals (T1, T2) of the windings (C) to an identical potential, and a regenerative mode for recovering electromotive force generated in the windings (C) into the power supply are executed as the rotor (2) rotates. The reflux mode and the regenerative mode are preferably repeated in a period during which the inductance of the windings (C) is reduced as the rotor (2) rotates.
