大扭矩均压行波超声波电机研究

Study of Large Torque Pressure-equalizing Traveling Wave Type Ultrasonic Motor

超声波电机的研究已成为全世界的热点。在ANSYS有限元软件分析计算的基础上 ,设计并制作了均压行波超声波电机 ,其直径为 10 0mm ,堵转转矩达 2 2N·m ,最高空载转速5 8r/min。采用定转子面接触模型 ,实现了电机的均压运行。对电机进行了输出性能测试和分析。

The research of ultrasonic motor has been turned into hotspot all over the world.This paper focuses on large torque pressure equalizing ultrasonic motor with one stator using traveling wave principle.It's diameter is 100mm,the braking torque reaches to 2 2Nm,and the load free revolution speed is 58 r/min.Using surface contact model between stator and rotor,the pressure equalizing operation is realized.On the base of analysis and calculation by using ANSYS,the pressure equalizing traveling wave type ultrasonic motor is designed and fabricated.The motor's performance is also tested and analyzed.The results approved the correctness of the model and design.
