Research on Speed Control Methods for Shinsei＇s USR60 Traveling Wave Ultrasonic Motor
Abstract：In this study,An experimental test set-up of USM is developed to examine the speed control methods of a travelling wave ultrasonic motor.Experimental results are taken from the ultrasonic motor drive and control system by separately applying three control methods which are amplitude,frequency and phase angle controls.According to the experimental results,the method on changing driving frequency gives more flexible control range than the other two methods.
