Abstract

This paper presents description of new design, its operation and primary research data of rotary piezotable driven by two harmonic signals. Synthesis of driving ring shape piezoelement and additional components ensures uniform motion of rotor. Supply of two harmonic signals, which are featured by distinct frequency and amplitude, to appropriately sectioned electrodes of piezoelectric ring-shaped transducer initiates specific rotational type oscilla-tions of the rotor. Experimental research provides a possi-bility to observe two oscillation-based operational regimes and one regime integrating both ordinary rotational motion and rotational vibrations effect.
