Multi-purpose Rotary and Linear Actuators
Piezo motors use a combination of piezo-electric and friction forces to generate a progressive motion of an output element. Such output motion can be a linear translation or a rotation in accordance with the actuation requirements of a particular application. Since piezo motors rely on friction at a controlled mechanical contact interface, the related tribology in vacuum and under varying temperature conditions is of critical importance for the function and operational lifetime of such motors.
