摘要： 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.

Winding attachment portions are formed between adjacent stator rings, and an annular winding is installed in each winding attachment portion for generating a magnetic field for rotating the rotor.

An interval between adjacent claw-shaped induction poles along the circumference of predetermined two of the stator rings of the three phases is smaller than an interval between adjacent claw-shaped induction poles along the circumference of any other pair of the stator rings.
