How do External Linear Stepper Actuators work? Unlike Captive and Non-Captive Stepper Actuators, external linear actuators use a nut in addition to the usual threaded leadscrew. As the motor rotates the screw, the nut translates the rotary motion into linear motion as it moves along the shaft of the leadscrew.
