How Does a Actuator Work?

Answer

An actuator is a mechanical device for moving mechanisms or systems. It works in a simple way. A small electric motor turns a series of spur gears. The last gear drives a rack and pinion gear set that is connected to the actuator rod. The rack converts the rotational motion of the motor into the linear motion that is needed to move the lock.

There are several categories of actuators. Mechanical, Hydraulic, piston, linear, cylinder and brake actuators. All work differently. Mechanical actuator for instance mimics muscle action to produce movement and force. Others also uses a mechanical device attached to the diaphragm to push and pull it into and out of the chamber.
