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.

Vehicle system, motor control system and motor control method

A powertrain for an electric vehicle includes: a motor that generates torque, a motor controller that controls the motor; a two-stage speed reducer connected to the motor and having a synchronizer movable to a neural position when the electric vehicle is parked; a pair of drive wheels connected to the two-stage speed reducer through a differential gear; a pair of electric parking brakes (EPBs) that locks or unlocks the pair of drive wheels, respectively, and a vehicle controller that controls the pair of EPBs. The synchronizer moves to the neutral position to prevent the torque of the motor from being delivered to the drive wheels.
