NEXACT® Piezo Stepping Drive from PI

This short video shows the compact NEXACT® Piezo Stepping Drive from Physik Instrumente (PI). The NEXACT® Piezo Stepping Drive from PI performs the stepping motion with bending elements. An ideal selection of the piezo elements enhances step size, velocity, clamping force, and stiffness for the respective requirements. The NEXACT® drive realizes velocities and develops forces from 10 to 20 N. As critical components, this piezo walking drives has several piezo actuators that are preloaded against a guided runner. These piezo actuators perform a walking motion when in operation, causing a forward feed of the runner. They can be worked to perform very small walking and feed motion so that a high motion resolution of far below one nanometer is accomplished.
