Piezo Motor Actuators & Stages (Ultrasonic Motors and Piezo Step Motors)
Piezo Flexure Stages     Piezo Stack Linear Actuators

Piezo linear motors can be divided into two groups: resonant motors (ultrasonic motors), and non-resonant motors. Both can, in principle, attain unlimited travel, yet they are very different in their design, specifications and performance.

Resonant motors are characterized by a simpler design and higher speeds, piezo step motors can achieve much higher resolution, forces and — over small distances — dynamic performance.

A great advantage of piezo motors is their intrinsic steady-state auto-locking capability. It does away with servo dither and the accompanying heat generation, an undesirable feature of electromagnetic motors. Step and continuous piezo motors are in principle nonmagnetic and vacuum-compatible, a requirement for many applications in the semiconductor industry.

In this demo, recorded at the 2004 BIOS Show San Jose, an M-661 is reversing directions between two hard stops as fast as possible. The stage exceeds the video frame rate, so listen to the sound for an indication of the real speed.
