Abstract: A novel rotary inchworm piezoelectric  motor was proposed herein. Considering the driving mechanism of the rotary inchworm piezoelectric motor was a continuous system, the dynamics model of the driving system was presented. The natural frequencies and mode function of the drive mechanism of a prototype were solved by using the dynamics model. The influences of system parameters on the natural frequency of the driving mechanism were analyzed. All the conclusions lay a theoretical foundation for the design of the rotary inchworm piezoelectric motors.

Key words: rotary inchworm;driving mechanism, modal analysis;piezoelectric motor
