Summary:•We present a theoretical model of the displacement distribution of a circular stator.•We construct an USM with the circular stator and a holographic interferometry system.•We conducted measurements by the holographic interferometer and a laser vibrometer.•We estimated the displacement distribution by a numerical simulation (FEA).•All the results agree with each other within the range of a few percent. 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.
