To provide an electric motor control system and an electric power steering apparatus that torque of the electric motor can be increased for ensuring of steering performance even at the time of abnormality occurrence. The controller is provided with 2 sets of control systems which control a supply current to each set of the windings. When abnormality occurs in one set of the windings and the control system, the electric motor control system sets 0 to supply current to all phase or partial phase windings of abnormality occurrence set, and increase supply current to normal set of the windings up to an irreversible current that increase an irreversible demagnetizing factor of the permanent magnet more than the normal time.
