一、要求和特点静电支承是一种没有机械接触的轴承,对它的要求是:(1)绝对可靠;(2)承受负载能力大;(3)对转子的电干扰力矩小;在作为静电加速度计使用的情况下,还要求:(4)支承力作为加速度计的输出量能精密测量,并以数字形式输出。静电支承是依靠高压电场的静电吸力来保证的。它的第一个特点就是高压电场可能发生 First, the requirements and characteristics Electrostatic support is a kind of bearing without mechanical contact, its requirements are: (1) absolutely reliable; (2) to withstand large load capacity; (3) the electrical interference torque of the rotor is small; as static In the case of an accelerometer, it also requires: (4) The supporting force, as the output of the accelerometer, can be accurately measured and output in digital form. Electrostatic support is relied on the electrostatic attraction of high-voltage electric field to ensure. Its first feature is that high voltage electric fields may occur
