资料介绍

该文在深入分析超声电机运行机理的基础上,从定子、接触区域和转子3方面建立了超声电机等效电路模型。综合现有超声电机等效电路模型的优缺点,考虑摩擦耦合对超声电机的影响,并结合转子振动方程,提出了摩擦层与转子的等效电路模型;对转子侧等效模型进行优化,使其与定子模型结合成完整的电机模型。基于所建立的模型理论,对等效电路进行仿真,仿真结果表明了转子对整个电机电气特征的影响。通过对实际超声电机的测试及其与仿真波形的对比,验证了所提出的行波型超声波电机等效电路模型的正确性,为进一步开展超声电机驱动器和控制器的设计提供了模型基础。

Based on the in-depth analysis of the operating mechanism of traveling wave ultrasonic motor(TRUM),the equivalent circuit model of ultrasonic motor is established from three aspects of stator,contact area and ding off the advantages and disadvantages of the existing equivalent circuit model of TRUM,considering the influence of friction coupling on the ultrasonic motor and combining with the rotor vibration equation,an innovative equivalent circuit model of the friction layer and the rotor is proposed in this the rotor-side equivalent model is optimized to integrate with the stator model into a complete motor ed on the established model,the equivalent circuit is simulated,and the simulation results show the influence of the rotor on the electrical characteristics of the whole validity of the proposed equivalent circuit model of TRUM is verified by comparing the testament results of the ultrasonic motor with the simulation provides the model basis for further design of driver and controller of the ultrasonic motor.
