摘要:
采用有限元法建立了佳能镜头上使用的中空环形行波超声波电机定转子接触模型.通过建立定转子有限元接触模型并在定子中性面上施加行波运动,得到定子齿表面质点的斜椭圆运动及其与转子的接触状态,比较了空载和堵转情况下定转子接触表面质点的法向和切向运动及定转子接触压力分布.空载和堵转时接触压力分布有明显不同,表明负载转矩对接触压力分布有影响.用实验数据对提出的理论模型进行了验证,理论分析结果与实验数据基本吻合.最后,对电机转子结构提出了改进方法,理论分析表明,采用改进后的转子,电机的转矩-转速特性有了明显改善.
Abstract:
The focus of this paper is to study the contact model of a hollow ring type traveling wave ultrasonic motor used in the Canon auto-focus lens with the finite element method. First, the finite element contact model is built and the traveling wave motion is applied to the neutral plane of the stator. The sloping elliptical motion of the stator surface and the contact status of the stator and the rotor are obtained. The motion of the stator and the rotor as well as the contact pressure in the contact surface are compared when the rotor is applied with no load torque and stalled. The contact pressure when the rotor is applied with no load is significantly different from the contact pressure when the rotor is stalled, which indicates that the load torque has an effect on the distribution of contact pressure. Then the proposed model is verified by experimental data. The analytical results are in good agreement with the experimental results. Finally, a new rotor is proposed and it is indicated that the torque-speed performance of the motor is optimized by adopting the new rotor.
