Study on the vibration displacement distribution of a circular ultrasonic motor stator.
In this paper is presented a theoretical consideration on the stator's displacement distribution, which is one of the most important problems in defining the structure of a circular ultrasonic motor stator. The results are compared with ones obtained utilizing a holographic interferometer, a laser vibrometer and FEM (finite element method) simulation. They are in good agreement with each other.
