This thesis is treating theory, modeling, model analysis and experiments of traveling wave type ultrasonic motors. A framework to derive models for ultrasonic motors is given here, which is based on the continuum theory of electromechanical solids. This includes the modeling of the stator-rotor contact and the electromechanical behavior of piezoceramic

Practical considerations in ultrasonic motor selection
Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010This article shows that using a piezoelectric motor in a mecatronic system, the thermal management is not an issue, as for conventional electromagnetic motors. We then show that choosing a motor on the maximal velocity or force/torque required in the application is not sufficient, and the motor selected may not be able to perform the motion profile. We

As a type of ultrasonic motors, a linear ultrasonic motor (LUSM) also utilizes the converse piezoelectric effect of piezoelectric ceramics and the ultrasonic vibration of an elastic body [1]. It transfers the micro amplitude motion of a stator into the macro linear motion of a slider by the friction force between the stator and slider.
