Claim 9:
10. A method of suppressing torque generation of a three-phase motor, the method comprising:
determining, by a torque determination device, a second torque value for suppressing a first torque value due to a zero phase sequence component current of the three-phase motor;
determining, by a control amount determination device, a voltage control amount for generating the determined second torque value;
determining, by a required current determination device, a required current value expressed based on a d-q axis for generating the determined second torque value;
determining, a required voltage determination device, a required voltage value expressed based on the d-q axis for generating the second torque value based on the determined required current value and the three-phase current value; and
controlling, by a controller, the three-phase motor according to the determined voltage control amount,
wherein the torque determination device configured to determine the first torque value based on zero phase sequence component flux of the three-phase motor, n-phase sequence component current value, and phase angle of the three-phase motor.
