The structure and performance of ultrasonic motors have gradually improved with the emergence of new materials, techniques, and structural forms. Therefore, the application scope of this technology is also expanding, especially in the field of high-end equipment. This paper conducts a review of research on the application status and progress at the frontier of research on ultrasonic motors. A summary and classification of both the status of application and cutting-edge research progress are presented, including the use of ultrasonic motors in aerospace, precision, biomedical and optical engineering and the influence on ultrasonic motor design resulting from the breakthrough in advanced processing and preparation technology, structural and functional integration technology, low voltage drives and open-loop control systems. Moreover, the performance of products developed with the aid of ultrasonic motors and representative devices are compared; and state of the art ultrasonic motor designs are discussed and summarized. Finally, potential future research efforts and prospects are highlighted.
