Advanced Q-Motion® Inertia Drive from PI

This video offers a glimpse of the Q-Motion® drive by Physik Instrumente (PI). Q-Motion® positioning systems close the gap which has not been covered by current drive technologies. The positioning system uses a piezo inertia drives that are space-saving and economical with relatively high holding forces and an almost  unlimited travel range. They provide high resolution and feature compact, versatile designs. They make use of the stick-slip effect (inertia effect) – a cyclical alternation of static and sliding friction between a runner and the drive element produced by the piezo element – for a continuous feed of the runner. The operating frequency of more than 20 kHz allows the runner to be directly driven at velocities in excess of 5 mm/second. Together with an incremental encoder for measuring the position, it is possible to achieve high positioning accuracy and repeatability of the motion over long travel ranges.
