摘要：

We propose a new ultrasonic motor, in which the rotor is levitated and driven to rotate at very high speed by the ultrasonic field radiated from the stator into the air gap between the rotor and the stator. The noncontact bearing-less structure of this motor makes it possible to exceed the revolution speed limit of conventional contact ultrasonic motors, and develop a new application of ultrasonic motors. Two motors with different resonance frequencies are fabricated, and their characteristics are investigated experimentally.
