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.

Technology

PiezoWalk® Walking Drives
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.

Vacuum
Careful handling, adequate premises: PI does not only have the necessary equipment for the qualification of materials, components and final products, but also has many years of experience with regard to HV und UHV positioning systems.

Incremental Sensors
PI uses incremental measurement systems for longer travel ranges, starting from approximately one millimeter. These sensors, which in most cases are optical sensors, achieve position resolution down to the picometer range.

Multi-Axis Positioners
Hexapod platforms are used for precision positioning and alignment of loads in all six degrees of freedom, three linear axes, and three rotational axes.
