摘要
The forming of elliptic motions on the modal conversion ultrasonic motors （MCUMs） is discussed. The principles of the modal conversion are investigated based on the coupling with the stator and the rotor, and using an independent coupler. The elliptical locus observed on the longitudinal-torslonal vibration converter with oblique slits is analyzed by using vibration theory. A method for the modal conversion is proposed by using the local mode of a substructure On a main structure. The method can be used to design the modal conversion type ultrasonic motors.
讨论了模态转换型超声电机表面质点椭圆运动的形成,研究了基于定、转子耦合和利用独立耦合器的模态转换型超声电机的原理。通过对具有斜槽的纵扭振动耦合器上观察到的表面质点椭圆运动进行的理论分析,提出了一种利用主结构中的子结构的局部振动获得模态转换的方法,可用于模态转换型超声电机的设计。
