双定子-双转子型大力矩超声波电机的研制
A High Torque Ultrasonic Motor Structured by Double-stators and Double-rotors
摘要
Abstract
In order to improve the output torque of a single-stator and single-rotor rotary traveling-wave type USM,a method using double-stators and double-rotors to constructure a new type USM with high output torque was proposed.Compared with the traditional USM,the output torque of the new type USM is about two times of the traditional USM only enlarging the length in the axial direction,but the driving power and the stator dimension are not changed.The structural perturbation theory was introduced to modify the modal frequency of the two stators.Experimental results show that the two stators have the same resonant frequency,and the output torque of the new type USM is about 1.1N·m,which demonstrates that the new type USM has good performance and wide application fields.关键词
