A motor control system shorts motor windings of a motor by using enhancement metal-oxide-semiconductor field-effect transistors (MOSFETs) so that the motor generates braking torque when all or some electric control units of the motor are disabled or failed. The motor control system comprises: a motor comprising a plurality of motor phase terminals; a plurality of electric control units electrically connected to the motor and configured to control the motor, wherein the electric control units configured to output control signals, respectively; a plurality of power sources, each of the power sources electrically connected to a respective one of the electric control units; and a shorting circuit connected between the power sources and the motor, the shorting circuit configured to selectively short the motor phase terminals in response to one or more of the control signals of the electric control units.
