Abstract
A valve actuator includes a motor, an AC power source, a DC braking system, and a control system. The control system is configured to control the AC power source to apply an AC voltage to the motor to drive a valve toward a closed position. The control system is configured to disconnect the AC voltage from the motor before the valve reaches the closed position. The control system is configured to control the DC braking system to apply a DC voltage to the motor to stop motion of the valve.
