Abstract: A rotary type ultrasonic motor with single phase driving circuit using standing wave is modeled to optimize the overall performance. Based on the Hamilton Principle, assuming pure slip contact in stator/rotor interface, the mathematical model is obtained. Then computer simulation model is set up in MATLAB language. And the simulation results is analyzed with graphical means.
Keywords: ultrasonic motor, standing wave, vibrating mode, simulation, model.
