Torque, revolutions and efficiency are investigated in a new type ultrasonic motor with a disk resonator using a shear mode to generate a driving force and a bending mode to control a friction force. The condition that these two modes have the same resonant frequency is realized by adjusting the disk resonator thickness and the contacting force against the disk resonator. The revolutions measured under load free and the restraining torque were to be 18 r.p.m. and 2.5 kgfcm, respectively. The maximum efficiency was 2% at the output torque of 1.6 kgfcm.
