Study on a New Type Traveling Wave Ultrasonic Motor

Liu Junkao

Abstract

A new type traveling wave ultrasonic motor is presented.It is different from some former motors whose rotor and stator are in frictional contact by several points during the dynamic process,and it is by the line during the dynamic process.The operating theory of the motor is derived from vibration theory.The stator model of the motor is built on software ANSYS.Each parameter of the stator has effect on the dynamic characteristic,which is analyzed in this paper.Kinetic characteristic of this motor is obtained through the experiment.
