Stick-Slip, Ultrasonic and Stepping Piezo Motors, More Information and Links to Applications. Other Linear Motors based Magnetic Drive Technologies are also available for automation purposes.Īll piezo motors and actuators are in principle nonmagnetic and vacuum-compatible, a perfect match for many applications in the semiconductor industry. Read Stick-Slip Performance Article.įlexure type piezo linear actuators are best used for smaller ranges but offer extremely fast response to microseconds. They are usually driven in step mode and PI motors run quietly at ulrasonic frequencies, however non-resonant. Piezo Stick-Slip motors (piezo inertial motors) are somewhat in between the ultrasonic motors and stepping motors. Piezo-Walk motors (piezo stepping motors) can achieve much higher forces and picometer range resolution but are not as fast. Ultrasonic resonant motors (PILine ®) are characterized by very high acceleration and speed to 800 mm/sec and feature a compact and relatively simple design. All three are self-clamping at rest and basically provide unlimited travel, yet they are very different in their design, specifications and performance. PI currently manufactures several basic types of piezoelectric motors: Ultrasonic motors (resonant motors), piezo stepper motors (PiezoWalk ®) and intertial motors. These compact, energy-efficient mechatronic mechanisms can be employed in precision motion control, replacing electrodynamic motors. Piezo motors are based on the piezoelectric effect.
