About Piezo Motor Company
Company Profile
Piezo Motor Company is a U.S.-based innovator in miniature motion control technology, specializing in ultracompact rotary and linear piezoelectric motors. Developed by a team of leading scientists and engineers, Piezo Motors' patented solutions offer exceptional precision, responsiveness, and reliability, making them ideal for cutting-edge applications where traditional motors fall short.
Unlike conventional electromagnetic motors, piezoelectric motors use vibration-driven ceramic resonators to create movement. This design delivers high-resolution positioning, no electromagnetic interference, silent operation, and instant braking without energy draw, setting a new standard for motion control in demanding environments.
