Abstract: A rotor includes a hub, a rotor core, holes and permanent magnets. Salient poles are each formed between neighboring openings on a circumference of the rotor core and, when viewed from a front along a line of axis of the rotor, a recessed portion that is formed by causing one portion of an inner circumferential surface of the rotor core to bulge radially outward of another portion is provided in a region enclosed by a first virtual line connecting a center of the hub and a circumferential middle position on the circumference of a magnetic pole of the rotor core having permanent magnets provided therein and a second virtual line connecting the center of the hub and a circumferential middle position on the circumference of the salient pole adjacent to the magnetic pole at a leading side in a rotational direction of the rotor.

Abstract: An electric vehicle employs an oil commonly used as a lubricating oil for gears and a coolant for a motor and is propelled by transmitting the rotational torque of the motor to wheels through the gears, the motor being partly immersed in the oil. It is determined whether the motor is in a state prior to being started or not. If it is judged that the motor is in the state prior to being started, coils of the motor are energized alternately with a first current supplied to the motor at an advanced angle for no torque to generate a magnetic flux, and a second current supplied to the motor at another advanced angle for no torque to generate a magnetic flux in a direction opposite to the magnetic flux generated by the first current, thereby heating the oil.
