| Abstract: | The operating principle,the constructional design and the selection of materials for a ringtype ultrasonic motor are discussed. A mathematical model for the compound vibrator of the stator,the key element of the ring-type ultrasonic motor, is developed by employing the concept of the equivalent beam. The analytical solution for the vibration mode is found. Simulation results and the dimensions of a sample motor designed are presented. The elliptic motion of the particles on the stator surface and the physical essence of the ultrasonic motor are analyzed. |
