摘要
总结了国内外计算静电悬浮球形转子的干扰力矩方法。基于静电力相对转子几何中心形成的力矩的计算,推导了半碗六电极悬吊转子装置的静电场基本干扰力矩计算公式。干扰力矩以转子失中度、非球度、转子极轴相对于电极坐标系的偏移、电极电压和电极槽描述。通过仿真,界定了满足一定干扰力矩的各因素的取值范围。研究结果对于球形转子平衡装置的研究与设计具有参考价值。
Based on summarizing and comparing the methods of calculating the disturb torque acted on electrostatically supported rotor, a proper method, that is calculating the torque caused by electrostatic force relative to rotor's mass center, is employed to get the torque in device with 6-electrodes construction which forms a half-bowl shape. The torque is described in terms of the rotor's eccentricity relative to the electrodes case, rotor's non-sphericity, the deviation angle of rotor's spin axis relative to shell coordinate, voltage on electrodes and empty electrodes which is not occupied by electrodes over the entire electrodes case's surface . Simulation results confirm the range of those parameters by which the disturb torque will be smaller than a certain value. The outcome is helpful to design the balance device for spherical rotor.
