A Study on the Characteristics of Windmill Type Ultrasonic Motor with Changed Endcap Shape Using FEM

FEM을 이용한 endcap 형상이 변형된 풍차형 초음파 모터의 특성연구

In this paper, we proposed windmill type ultrasonic motor which has modified shape of Endcap. The motor was especially designed by FEM for high speed. As results, displacements of the windmill and the clover type motor was compared. Using clover type motor, more smooth rotation of rotor was achieved. If Z component of the displacement of the clover type motor can be applied for linear motor.
