Ultrasonic Motor Techniques for 21st Century

Firstly, a review of the development and applications of the ultrasonic motor techniques since the seventies of the last century, both at home and abroad is outlined, and a presentation of progress in the research on the techniques in the Research Center of Ultrasonic Motors of NUAA is summarized. Secondly, the author predicts that a great and growing market for the motors will be found in the 21st century, and the techniques will have a good future of applications in the building of national defense and economy. Finally, the trend of the development of the motor in the 21st century is pointed out. According to the actual condition of the studies for the techniques in China, some key problems, which are urgent for further development of the technologies in the new century, are proposed in the paper.
