ABSTRACT:
In a motor controller, if a failed electric current flow in any one of phases of a motor is detected, a motor control signal is generated, based on a phase other than the phase with the failed electric current flow, in such a manner that a motor electric current matches a required torque except for at a specific rotation angle corresponding to the phase with the failed electric current flow.
