What sets PiezoMove actuators apart are the internal frictionless flexure-guides, making additional bearings or guiding mechanisms obsolete when integrating the actuators into a positioning system.
PI (Physik Instrumente), a manufacturer of nanopositioning and precision motion-control equipment for photonics, semiconductor and life science applications, offers the new compact PiezoMove lever amplified Z-actuators.
PiezoMove vs conventional lever amplified actuators.
Lever amplified piezo actuators provide significantly longer travel ranges than standard, direct drive actuators.
What sets PiezoMove actuators apart are the internal frictionless flexure-guides, making additional bearings or guiding mechanisms obsolete when integrating the actuators into a positioning system.
Three versions providing up to 480um travel are available.
Closed-loop option offers nanometer precision.
Piezo actuators can basically move in sub-nanometer increments.
However, open-loop actuators do not provide high linearity/repeatability.
PiezoMove actuators are available with integrated, absolute-measuring position sensors for closed-loop operation with high linearity (99.8%) and nanometer range repeatability.
Very fast response: millisecond settling times.
The stiff design with high resonant frequencies to 750Hz allows settling times of only a view milliseconds, ideal for highly dynamic applications.
Ceramic-encapsulated actuators for long lifetime.
Reliability is assured by the use of award-winning Picma multilayer actuators, which are integrated into a sophisticated, single-module, flexure guiding system.
The Picma actuators feature co-fired ceramic encapsulation and thus offer better performance and reliability than conventional piezo actuators.
The wire-EDM-cut flexures are FEA modelled to make them extremely precise.
In addition they are maintenance-free and not subject to wear.
Typical applications: nanopositioning, semiconductor testing, adaptronics , photonics / integrated optics, biotechnology.
Features and advantages: flexure guidance for frictionless, ultra-straight motion; low cost, custom designs; travel ranges to 480um; resolution to 0.2nm; high dynamics and stiffness; Picma high-performance piezo actuators; open and closed-loop versions.
