Stepping piezoelectric actuators based on the stick-slip effect inherently make use of a friction contact between stator and rotor. This contact defines not only the actuator’s performance but also is prone to wear and tear. For broad use, the actuator has to be able to perform around 1 million strokes. To assess the actuator’s performance in terms of force, speed, mechanical output, electrical input, and long-term stability under different load- and environmental conditions, as well as different friction partners, a dedicated test-bed for a LSPA30μXS motor by Cedrat Technologies has been set up.
