High Speed Ultrasonic Piezo Linear Motor Drive	Stick-Slip (Inertia) Piezo Motor Principle	Low-Profile Rotary Piezo Motor Stage	PiezoWalk^® Motors Force + Precision

Piezo motors are based on the piezoelectric effect. These compact, efficient mechanisms can be employed in precision motion control applications, replacing electrodynamic motors.

PI currently manufactures three basic types of piezoelectric motors: Ultrasonic motors (resonant motors), piezo stepper motors (PiezoWalk^®) and intertial motors. All three are self-clamping at rest and basically provide unlimited travel, yet they are very different in their design, specifications and performance.

Ultrasonic resonant motors (PILine^®) are characterized by very high acceleration and speed to 800 mm/sec and feature a compact and relatively simple design.

Piezo-Walk motors (piezo stepping motors) can achieve much higher forces and picometer range resolution but are not as fast.

Piezo Stick-Slip motors (piezo inertial motors) are somewhat in between the ultrasonic motors and stepping motors. They are usually driven in step mode and PI motors run quietly at ulrasonic frequencies, however non-resonant. Read Stick-Slip Performance Article.

Flexure type piezo linear actuators are best used for smaller ranges but offer extremely fast response to microseconds.

Other Linear Motors based Magnetic Drive Technologies are also available for automation purposes.

All piezo motors and actuators are in principle nonmagnetic and vacuum-compatible, a perfect match for many applications in the semiconductor industry.
