Bi-phase inertia drive technology
Piezo inertia drives are space-saving and affordable piezo-based drives with relatively high holding forces and a virtually unlimited travel range. The inertia drive principle is based on two piezoelectric actuators that are controlled with a modified sawtooth voltage provided by special drive electronics. The actuators expand slowly and move the runner.
Due to its inertia, the runner is unable to follow the subsequent fast contraction of the actuators, and remains in its position. A symmetrical motor setup guarantees consistent drive characteristics in positive and negative directions of motion.
The drives acting directly on the runner achieve velocities of max. 14 mm/s with an operating frequency of up to 20 kHz.

Unidirectional repeatability in X: Mean value.
At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.
