| Abstract: | The operation mechanism of a ring -type ultrasonic motor is discussed in this paper. The mathematical model of the compound vibrator of the sta-tor, the key structure element of a ring-type ultrasonic motor is established by introducing the concept of equivalent beam for the first time. The analytical solution and the simulation results of the vibration mode are presented. And the elliptic motion of particles on the stator surface and the basic principle of the ultrasonic motor are analyzed. Moreover, the actual structure of the sample motor is offered. |
