How Piezoelectric Motors Work

Piezoelectric motors work by harnessing the piezoelectric effect, the ability of certain materials to generate an electric charge in response to applied mechanical stress. The piezoelectric material is typically a ceramic, such as lead zirconate titanate (PZT), that is sandwiched between two electrodes. When an AC voltage is applied to the electrodes, the piezoelectric material expands and contracts, causing it to bend and generate motion. This motion is then used to drive a rotary or linear actuator, depending on the type of piezoelectric motor. The movement produced by piezoelectric motors is precise and rapid, making them ideal for applications that require high precision and speed, such as micropositioning, scanning, and control systems. Additionally, piezoelectric motors consume very little power, making them highly energy-efficient and environmentally friendly.
