Piezoelectric Motors: Understanding "Squiggle" Motors and Ultrasonic Drives

Piezoelectric motors are revolutionizing precision motion control in industries where compact size, silent operation, and high-resolution positioning are critical. Unlike conventional electromagnetic motors, piezoelectric motors rely on the deformation of piezoelectric ceramics to generate motion—offering distinct advantages in specific applications. In this article, we explore the principles behind piezoelectric motors, with a special focus on ultrasonic motors and "squiggle" motors, and examine their key applications across various industries.

What is a Piezoelectric Motor?

A piezoelectric motor is a type of actuator that uses the deformation of piezoelectric materials to produce mechanical displacement. When a voltage is applied to these materials, they change shape—expanding or contracting at microscopic scales. By carefully controlling the input signal and structural configuration, this deformation can be converted into controlled rotary or linear motion.
