How a Linear Actuator Works

Simply stated, all linear actuators depend on an external, non-linear force to drive some kind of a piston back and forth, yet, different types of linear actuator work in different ways. A ‘piston" is defined as sliding piece which is moved by or against fluid, air pressure, or electricity. It usually consists of a short cylinder fitting within a cylindrical vessel along which it moves back and forth. For example: in steam engines, motion is created by steam, and pumps transmit motion to a fluid. 

Hydraulic pump actuators for example, depend on a hydraulic pump to compress and decompress the two sides of a piston in order to push it back and forth. The piston is attached to an external shaft, so the shaft moves with it. On the other hand, a wax motor linear actuator uses an electric current to melt a block of wax, causing it to expand. As the wax expands and contracts with varying electrical currents, a plunger that is pressed against it moves back and forth in a linear motion.
