A Wax Motor is a linear actuator and is mostly used to replace a magnetic solenoid in an application, wherein, a short range of linear movement is needed. Our wax motor has three main components:

A block of wax

A plunger that bears on the wax

An electric heater, typically a PTC thermistor, that heats the wax

As the electric heater gets energized, it heats the wax block and expands it, driving the plunger in an outward movement. When the electric current is detached, the wax block cools & contracts and the plunger is taken out. It happens when a spring force is applied externally or when the spring is implemented directly onto the wax motor.
