N2 - A new analytical model for traveling-wave piezoelectric ultrasonic motors (TWUSM) is developed and experimentally verified in this study. The proposed model consists of two parts: one is for modeling mechanical vibrations of the stator with forced vibration equations, and the other is for modeling the contact between the stator and the rotor with consideration of the stick-slip behavior. The mechanical characteristic of the proposed model, with various control variables and constructional parameters, are investigated in simulations and experiments conducted on a self-manufactured motor prototype. It is shown that experimental results are in good agreement with simulation results, which verifies the effectiveness of the proposed model.
