Abstract
A failure determination method for a motor system includes setting a current value required to initially drive a motor to a first current command value, increasing a rotational speed of a rotating magnetic field of the motor up to a preset reference speed, comparing an intensity of a back electromotive force, generated when a rotor of the motor is rotated at the preset reference speed, to a magnitude of a voltage applied to apply current in accordance with the set first current command value, and determining a cause of a failure of the motor based on the comparison.
