Design, Simulation and Experimental Validation of a New Concept of Ultrasonic Piezoelectric Moto-reducer with Embedded Strain Wave Reducer

In order to overcome the torque limitation of current piezoelectric motors we propose a new motor concept with an embedded strain wave reducer. It combines an ultrasonic motor based on a simple disk-shaped piezoelectric buzzer with a flat strain wave reducer. In this paper, we focus on the characterization of the ultrasonic piezoelectric motor for this moto-reducer.
