Abstract
A motor control system is provided. The system includes an inverter that adjusts a stator current applied to a stator coil of a wound-rotor drive motor and a rotor current applied to a rotor coil of the drive motor. When an abnormal starting of the drive motor is detected and a movement of the vehicle is restricted by electronic parking brakes (EPB), a motor controller adjusts the rotor current through the inverter to cancel an abnormal starting torque caused by the abnormal starting.
