Piezoelectric Actuator, Ceramic Component Polarizing Method and Piezoelectric Motor System

摘要

The piezoelectric actuator of the present invention has at least one ceramic component. The ceramic component has an output surface and two driving surfaces. The ceramic component has a height and the output surface is rectangular in shape, wherein the length of the short axis side of the output surface is shorter than the height. Therefore, when a pulse wave input voltage is applied on the driving surfaces, the output surface generates an elliptical motion.
