| description | A motor control system to drive an alternating-current (AC) motor, including a motor drive with a power circuit and a motor drive controller powered by the power circuit and configured to cause the power circuit to generate a motor voltage; a motor drive contactor having first contacts electrically connected between the power circuit and the AC motor; a bypass contactor having second contacts electrically connected between a line voltage source and the AC motor; and a bypass controller communicatively coupled with the motor drive contactor and the bypass contractor; wherein the motor drive controller is structured to generate a speed reference and to command the bypass controller to connect the AC motor to the line voltage source upon the motor drive controller determining that the speed reference is substantially equal to a line frequency of the line voltage source. |
