New high-performance HVPZT piezo actuators with E-508 amplifier module.

Abstract:
Piezo specialist PI has introduced 4 new series of high-force, high dynamics piezoelectric stacked actuators and a new line of linear amplifiers. While most low and medium force actuator applications are covered by the company's patented PICMA® multilayer technology, the PICA™ stacked actuator technology enables applications where extremely high forces and dynamics are required or high levels of customization are needed.

Piezo Ceramic Linear Actuators & High-Voltage Amplifiers Provide Higher Forces, Dynamics

Auburn, MA | Posted on January 17th, 2008

Typical Applications: Precision Engineering / Micromechanics, Nanotechnology, Adaptive Mechanics, Active Vibration Damping, Adaptronics, Static and Dynamic Precision Positioning, Force Generation / Materials Testing, Optics, Metrology / Interferometry, Switches, Laser Tuning.

Features & Advantages of PICA™ Power Stacked Piezo Actuators:

- High Force Generation to 30,000 N (3 Tons), Microsecond Responsiveness
- Closed-Loop Option for Higher Linearity, Sub-Nanometer Precision
- High Levels of Customization
- High Temperature Option, Low Temperature Option, High Vacuum Option
- Water Proof Option

Lower Power Consumption, Forces to 3 Tons, Travel to 180 µm, Sub-Nanometer Resolution, more than 100 Standard Models

The four newly developed piezo actuator series (P-212, P-216, P-225 and P-235) are equipped with the advanced PIC 255 PICA™ Power piezoceramic stacks. They come with load capacities from 2,000 N to 30,000 N and travel ranges from 15 µm to 180 µm. More than 100 standard models are offered. All actuators provide sub-nanometer resolution and are available with position feedback for better positioning accuracy. The integrated preload makes these actuators ideal for dynamic applications (e.g. precision machining, active vibration damping, etc.) and push-pull applications. The low-capacitance, piezo ceramics require less electric power than similar actuators - a special advantage for high dynamics applications.

Five ew High Voltage Amplifiers, Power from 1 to 2000 W

Five RoHS compliant high-voltage amplifiers ranging from 1 to 2000 watts of power are available to drive the new preloaded piezo actuators. All models
(E-462, E-464, E-508, E-421 / E-470 / E-471 / E-472, E-481) are delivered preset to provide 0 to 1000 V output voltage and most can also be run in bipolar mode.

High Displacement with Ultra-High Reliability, >1,000,000,000 Cycles PICA™ Power actuators are optimized for high-duty-cycle dynamic applications and high-temperature working conditions. With PI's extensive applications knowledge, performance does not come at the price of reliability. All materials used are specifically matched for robustness and lifetime. Endurance tests on PICA™ actuators prove consistent performance, even after billions (1,000,000,000) of cycles.
