英文摘要：

In this paper, the traveling wave type ultrasonic motor with 60mm in diameter was taken into account. By studying the contact model of the ultrasonic motor＇s stator and rotor, a simulation model with the stator teeth＇s effect was found. By solving this simulation model with the actual ultrasonic motor structure parameters, the operating characteristics of the ultrasonic motor was obtained. Finally, the test was complete. The similarity of test results and simulation results showed the validity of the simulation model.
