Practical considerations in ultrasonic motor selection

This 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 then propose a selection procedure based on the maximal mechanical power required for the application.
