    Abstract: A brake actuator has a motor that provides input rotation in first and second directions. A reducer couples to the motor and reduces the input rotation into an output rotation to be applied to a brake screw of a progressive cavity pump drive. A sensor measures rotational speed of the drive shaft. In manual operation, an operator can view an indication of the rotational speed and can manually operate the motor accordingly to control rotation of the shaft. In automated operation, a controller automatically controls the motor based on the rotational speed measured by the sensor. The controller can also use a torque sensor to detect the torque applied to the brake screw, a displacement sensor to detect displacement of the brake screw, and/or a current sensor to detect the current consumption of the motor.
