NEXLINE® PiezoWalk® Motors from PI

This video shows the NEXLINE® PiezoWalk® motors, which offer high forces and nanometer precision motion with multiple operating modes. The multiple operating modes deliver optimized performance for speed, force, and holding force. The construction of the NEXLINE® PiezoWalk® motors is a combination of linear piezo actuators and shear actuators working together. A digital controller coordinates the preloaded elements. A parking mode allows the actuator maintain a nanometer-stable position without a driving voltage. Forces of nearly 1 kN can be realized with this principle. Actuators and comprehensive multi-axis motion systems are available.

The full step mode offers the highest velocity and highest dynamic forces. The nanostepping mode offers the best uniformity of motion and lowest vibration. The analog/dither mode provides very high dynamics millisecond response, picometer resolution, and 5 µm travel range.
