A motor control system comprises: a motor comprising motor windings; and electric control units connected with the motor, each of the electric control units comprising an inverter. One of the electric control units comprises: a direct current (DC) bus; first switches, each of the first switches connected with a respective one of the motor windings; second switches, each of the second switches connected with the DC bus and a respective one of the motor windings; a first switch driver generating drive signals to drive the first and second switches; pull up resistors, each of the pull up resistors connected between the DC bus and a respective one of the second switches. The voltage pulled up by the pull up resistors can force the second switches to be turned on to short the motor windings in a state that the first switch driver does not generate the drive signals.
