The wax motor is a compact and essential component found in thermoactuators. It comprises a sealed container filled with solid wax, a positive temperature coefficient thermistor (PTC), and a piston. iSwell's wax motors feature a plunger-type structure, allowing them to efficiently convert thermal energy into force and produce linear movement through the volumetric expansion of wax.
When the PTC heats up, the solid wax inside the container melts and expands. This expansion causes the piston to move outward as the liquid wax fills the available space. The force generated by the wax phase transition is substantial and provides excellent actuation capabilities.
Wax motors offer numerous advantages, including their compact size, ease of control, high force output, and silent operation. Their versatility makes them suitable for a wide range of applications, and there are still many untapped possibilities for utilizing wax motors.
