A linear actuator is simply a motor that has been geared for linear movement as opposed to rotational movement. RC Servo linear actuators, like their rotational counterparts, have a built-in control system that allows them to actuate to a specific position. DC linear actuators behave by default like DC motors, moving as fast as they can when power is supplied to them. Our DC linear actuators all come equipped with feedback potentiometers so that their position can be monitored and controlled in software.
