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.

Velocity in full-step mode: Depending on drive electronics.

Velocity in nanostepping mode: Depending on drive electronics. The maximum velocity in nanostepping mode is designed for the best possible constancy so that no velocity variations occur when performing the steps.

Drive force: Data refer to full step mode operation.
