Abstract
In this study, a single phase driven piezoelectric motor design is presented for linear motion-metal/ ceramics composite structure. Using ANSYS finite element analysis software, mode shape of free motor was obtained to clarify the working principle of this motor. And characteristics of the motor was measured. The motor is composed of a piezoelectric ceramic, a metal ring which has 4 arms, and a guider. The motor with 25.0[mm] diameter was studied by finite element analysis and experimentation too. As a result, the motor was expressed the best speed in resonance frequency. And according as voltage of the motor increase, the speed increased by ratio.
