Abstract—The authors are developing multi degree of freedom micro spherical ultrasonic motor using wire stator for endoscope. In the previous study, the authors investigated the driving characteristics by using a single spiral wire stator of 15 times model as experimental equipment. In this study, assuming the introduction of a vascular endoscope, the authors design a wire stator and perform a transient response analysis by the finite element method. It is aimed to investigate the influence of the attenuation of the traveling wave transmitted on the wire stator by changing the condition of the model by this analysis. In the future, the authors will measure the amplitude of the wire stator by experiment and verify the accuracy of the simulation.
