Abstract

We propose a multimodal model to realize the bidirectional motion of a self-clamping linear piezoelectric motor driven by a single harmonic signal based on previous motor research. Compared with the previous version, only the characteristics of the drive signal need to be changed in the motor without changing any other conditions to excite multimode and achieve reverse movement. The finite element software COMSOL^5.2 was used to simulate the mode of the motor. The prototype has a maximum output speed of 71.5 mm/s, a maximum traction of 0.9 N at a voltage of 220 V_p-p, a frequency of 536 Hz, and a preload of 2 N. The minimum resolution of 26.4 µm was achieved at no-load, a voltage of 120 V_p-p, and a preload of 0 N.
