Abstract

A motor that utilizes multilayer piezoelectric devices for electromechanical power conversion and the mechanism of the strain wave gearing for generation of traveling motive forces is proposed. The construction, basic operation, and torque generation mechanism of the motor are described. The motor can be operated under variable frequency. Experimental results on the prototype motor made of metals are also presented. The feasibility of the proposed motor is verified, and the possibility of realizing piezoelectric motors with a larger torque is shown
