| Abstract: | The elliptical motion on the stator of cylindrical ultrasonic motor was analyzed herein. The elliptic motion of the particle on stator was decomposed into the effective elliptic motion and the linear slip. Three types of motor with different driving surface were researched to find their different characteristics of the effective elliptic motion and linear slip by simulation method. The results show that there is no linear slip on the middle part of cylindrical surface of the stator. The researches offer theoretical basis for improving the efficiency and simplifying the structure of this type of motor. |
