Ring-type traveling wave ultrasonic motor using a radial bending mode

IEEE Trans Ultrason Ferroelectr Freq Control. 2014 Jan;61(1):197-202. doi: 10.1109/TUFFC.2014.6689788.

Abstract

A traveling wave ultrasonic motor utilizing a radial bending mode of a thick ring is proposed. Twenty PZT stacks and 20 block springs are nested alternately into 40 slots cut in the ring's outer surface to produce a traveling wave. The prototype achieves maximum speed and torque of 146 r/min and 1.0 N·m, respectively.
