(Received December 8, 1993; accepted for publication February 19, 1994)

A Noncontact-type ultrasonic motor driven by the radiation pressure of the sound waves can be rotated well and miniaturized. In the previous study, the maximum revolution speed reached 4,000 rpm in the case of a small ultrasonic motor of 5 mm diameter and 0.5 mm thickness. In this paper, a consideration of the driving force of such a noncontact ultrasonic motor is described.
