摘　　要：超声波电机具有低速大力矩、响应快、分辨率高和抗电磁干扰等优点,能直接驱动,使其在机器人、工业仪器仪表、安防等领域有着广阔的应用前景。多自由度是超声波电机研究领域的前沿课题。分类探讨了近年来出现的几种多自由度超声电机的结构、机理、性能及其特点,给出一些具有代表性的实例,总结了多自由度超声波电机的主要研究成果和应用状况,对多自由度超声波电机的今后研究重点和发展方向提出了建议。Ultrasonic motors (USM) have the advantages of low speed, high torque, quick response, high resolution and anti-electromagnetic interference capability, which bring them broad application prospect in fields of robots, industrial instruments and security technologies. Multi-degree-of-freedom (MDOF) motor is one of the most cutting-edge aspects in the ultrasonic motor researches. Several typical MDOF ultrasonic motors of different types were introduced. The structure, working principle and characteristics were mainly discussed. Some typical examples were given and the key achievements were summarized, as well as their applications. The research and development trends were proposed.
