Nanometer precision and high feed force with PiezoWalk® walking drives
Several piezo actuators perform a walking motion in the PiezoWalk® walking drive that leads to forward feed of a runner. Control of the actuators allows the smallest step and forward feed motion at a resolution of well under one nanometer.
Highly accurate position measuring with incremental linear encoder
Noncontact optical encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement.
Suitable for sophisticated vacuum applications
Piezo motors from PI can be designed for use in a vacuum and are suitable for operating in strong magnetic fields. Special versions of the drives are available for this purpose. Piezo walking drives can also be used in cleanrooms or in environments with strong ultraviolet radiation.

Technologie
Moteurs PiezoWalk®
PiezoWalk® drives were developed more than 10 years ago for the semiconductor industry, a demanding industry when it comes to reliability, position resolution and long-term stability.
Capteurs incrémentaux
PI utilise des systèmes de mesure incrémentaux pour des gammes de déplacements plus longues, à partir d'un millimètre approximativement. Ces capteurs qui, dans la plupart des cas sont des capteurs optiques, offrent une résolution de position de l'ordre du picomètre.
Positionneurs multiaxes
Les plateformes hexapode sont utilisées pour le positionnement de précision et l'alignement de charges selon six degrés de liberté, trois axes linéaires et trois axes rotatifs.
Vide
Manipulation précautionneuse, locaux adéquats : PI dispose non seulement de l'équipement nécessaire pour la qualification de matériaux, de composants et de produits finis mais s'appuie aussi sur de nombreuses années d'expérience en matière de systèmes de positionnement sous vide et ultra vide.
