Abstract

In this paper, vibration mode of Windmill type Ultrasonic Motors was analysed. We used the ANSYS program to analysis by FEM. Vibration Mode express 20 modes as each resonance frequency. We bind nearly same modes and compress 5 modes. Windmill type Ultrasonic Motor's rotation is generated the friction of rotor at top endcap. Thus, We will find the best driving frequency that generating large friction at top endcap.
