The Wide Variety of Piezo Stack Actuators
Piezo actuators offer small precise fast repeatable motion in one axis. They have extremely long lifetimes, and some models can move very large masses for shake or shock material testing applications.
A stack type piezo actuator is built using multiple layers of ceramics. A special epoxy sealing guarantees a flexible, lifetime of protection. This technique has been proven in the field by many years of extensive experience.
Depending on the size of the ceramic stacks, these actuators can move masses in the kNs. The resolution is only limited by the signal noise of the amplifier.
High power, high force hpower piezo actuators are available and especially useful for material testing as shakers and for shock generation.
The ability to generate a large force and be subjected to high mass loads with high resolutions makes stack piezo actuators particularly useful for machine tools and dynamic scanning systems.
Specifics:
Multi-layer piezo actuators are successfully used in applications in the fields of nano-positioning, metrology, rapid valve actuation, mirror moving and tilting, fiber stretching, generating oscillations, and vibration damping.
As an option, these piezo actuators are all available with a strain gauge feedback sensor. And there is also a vacuum or cryogenic version.
