PI’s high-displacement series of motion amplified piezoelectric actuators integrate a low voltage, multi-layer piezoceramic stack in a flexure guided housing assembly. The flexure provides guiding, preload, and doubles as a motion amplifier. It also protects the ceramic stack and simplifies mounting as well as attaching the object to be moved to the part of the motion output. PI amplified piezo actuators provide high force, high stiffness, speed, and precision. They integrate the patented PICMA® piezo actuators that ran 100 Billion cycles in NASA tests before they were sent off to Mars.
Closed-Loop Control Option: Closed-loop position control is possible with a piezo servo controller based on the feedback signal from the integrated high resolution position sensor. Closed-loop piezo control eliminates non-linearity and hysteresis effects and provides significantly higher precision.
Applications: PI high-displacement amplified piezo actuators can be used for many applications, including high speed valves, dosing and pumping, optics alignment, nanopositioning, nano-dispensing, biotechnology, microfluidics, medical-devices, microscopy and life-sciences, and many other applications that require motion with high precision, high speed and ultra-high reliability, free of wear and maintenance.
Why use PI Amplified Piezo Actuators?
Amplified Piezo Actuators can provide significantly longer travel ranges than the piezo stacks that drive them. PI has extensive experience in modelling flexures for extreme lifetime, guiding precision, high bandwidth, and frictionless, nanometer precise motion. In addition of the standard flexure amplified actuators shown below, PI has designed hundreds of custom models specifically tailored to our OEM’s application requirements – talk to a PI Engineer for details.
