Abstract

Based on the understanding of operation principle of traveling wave rotary ultrasonic motor, the physical condition is investigated for the disk stator with orthogonal vibration modes of the same frequency. It is pointed that the stator teeth have effect on geometry axial symmetry of the disk stator in addition to the increased driving for the rotor. Through qualitative analysis of dynamic equation for the disk stator, essential dynamics of orthogonal vibration modes with inconsistent frequency is studied, and the criterion is proposed. Finally the presented prototype experiments illustrate the effect of the teeth on the orthogonal vibration modes of disk stator with inconsistent frequency.
