Electric Motor (Piezoelectric)

Conversely, the application of an electric field enables certain materials to alter their shape or size. Piezoelectric motors utilize this dynamic ability to generate motion. piezoelectric motors generate motion through the physical deformation of piezoelectric materials. Due to their one-of-a-kind operation, piezoelectric motors are optimal for applications that require precise positional control since they are able to produce motion that is both very precise and controllable at a smaller scale.
Materials such as quartz, Rochelle salt, and synthetic crystals such as lead zirconate titanate (PZT) are used to manufacture piezoelectric elements, which are the fundamental components of piezoelectric motors. These elements, when exposed to an electric voltage, undergo controlled deformation, enabling them to convert electrical energy directly into mechanical energy.
Piezoelectric motors stand out for their ability to maintain their position even in the absence of power, only using energy when necessary for movement.
