Rotary ultrasonic motors: daimler- benz awm 90–x twusm motor, experimental and simulation mechanical characteristics

Abstract EN

Rotary ultrasonic motors have now been investigated for several years.

Their key features are high thrust forces related to their volume and good position-accuracy.

This study is consisted by two main parts.

In the first we describe the development of the structure and working principle of the piezoelectric motors.

In second we present Daimler –Benz AWM90-X Motor as technical example of ultrasonic motor by their data information’s delivered by the manufacturer and as simulation of the implementation of functional mathematical model on Matlab / Simulink software results.

Results of the simulation are validated using the measurements made by other researchers on traveling wave piezoelectric motor AWM90-X Daimler-Benz type and a prototype USM (AWM -90).
