- Abstract
Nowadays, piezoelectric linear actuators draw wide attention of researchers around world as its advantages of simple structure, high precision and rapid response. To improve the performance of the non-resonant piezoelectric motor, a symmetric piezoelectric linear motor driven by double-foot is studied in the paper. The vibration model of the stator is established based on the structure and the working mechanism of motor. Then guide mechanism and preload device is designed and a prototype is fabricated to verify the feasibility of structure. The performances of motor under different driving signal are tested in experiment. By applying three-phase square-triangular waves signal and four-phase sine waves signal of peak to peak value 100 V with 50 V offset and frequency of 100 Hz, the speed of prototype reaches 733 µm/s and 667 µm/s and the maximum thrust is 8.34 N and 6.31 N respectively.
