超声马达是一种新型原动机，与普通电磁马达不同，这是一种摩擦驱动马达．为了促进超声马达的发展，对其研究中关于定子与转子界面接触驱动特性和摩擦磨损特性，超声波振动对定子和转子接触界面摩擦学特性的影响，转子摩擦材料的选择及其寿命预测等，从摩擦学角度对国内外的研究进展进行了综合归纳与评述，并且针对超声马达摩擦驱动的特点，提出了当前值得重视的一些研究内容．
Ultrasonic motor is a new type of prime mover, and ordinary electromagnetic motor is different, this is a friction drive motor. In order to promote the development of the ultrasonic motor, the influence of the contact and driving characteristics and the friction and wear characteristics of the stator and the rotor interface, the tribological characteristics of the ultrasonic vibration on the contact interface between the stator and the rotor, the choice of the rotor friction material and the prediction of its life are studied Tribological perspective of the research progress at home and abroad were summarized and commented, and in view of the characteristics of ultrasonic motor friction drive, put forward some worth paying attention to some of the current research.
