Claim 5:
6. A control method for a double wound motor, the control method comprising:
storing a plurality of current control commands corresponding to pre-stored different patterns of torque ripple;
checking a pattern of torque ripple in the double wound motor; and
outputting one of the stored current control commands corresponding to the checked pattern of torque ripple,
wherein the control method further comprises:
storing another pattern of torque ripple when a winding of the first or second winding unit is short-circuited to ground or when a short circuit occurs between the winding of the first winding unit and the winding of the second winding unit; and
performing current control differently depending on which short circuit occurs among a short circuit between the ground and the winding of the first or second winding unit and another short circuit between the winding of the first winding unit and the winding of the second winding unit.
