Construction of Ultrasonic Motors and their Application

Abstract

This paper deals with construction of an ultrasonic motor and their application; a paper-sending device using a flat rectangular type ultrasonic motor is described. Various types of ultrasonic motors can be constructed by considering displacement combinations in the horizontal and vertical directions at the elliptic motion yielded. As for this elliptic motion, multi-mode vibrators using degenerate modes of the same or different form are utilized.
