PRZEGLĄD WYBRANYCH TOPOLOGII AKTUATORÓW PIEZOELEKTRYCZNYCH REVIEW OF CHOSEN TOPOLOGIES OF PIEZOELECTRIC ACTUATORS

The aim of this paper is to present the theoretical background, gather essential knowledge to further research and to build measurement stand for acquiring characteristics of piezoelectric motors. The fundamen- tals of piezoelectric phenomenon have been presented. Chosen topologies of piezo-actuators working in spe- cial applications (especially robotics, automotive industry and aeronautics) have been described. Special em- phasis was put on traveling wave ultrasonic motors, high torque piezo-motors and multiple degrees of freedom novel piezo-motors. The automatic method of obtaining characteristics of piezoelectric actuators was present- ed. The main attributes of piezo-drives have been discussed.
