Abstract：Recently, actuators and transducers using piezoelectric materials have been widely used in the industries. A new bar-type ultrasonic motor of small size is designed in this work. The analytical model based on Rayleigh theory and equivalent method is established. An exact analysis for the displacement at resonance by introducing loss coefficients is also presented. Model calculations are compared with Ansys finite element analysis simulation results and good agreements are found. The model can be utilized for the optimization of the ultrasonic motor and other piezo-systems.
