电磁悬浮转子微陀螺(MGELR)是一种新型的角速率传感器,它和传统机械陀螺具有相同的工作机理。MGELR有望成为具有高精度的微陀螺。对于MGELR来说,转子的稳定悬浮是极为重要的。文中对微转子的稳定悬浮进行了全面的研究。详细分析并给出线圈、转子直径、电流幅值、悬浮高度等因素对微转子悬浮稳定性的影响。文中提出边界效应理论来解释微转子偏心所带来的侧向力。试验结果进一步论证了分析的正确性。文章最后得出稳定悬浮所应满足的条件。文章的研究内容为MGELR的结构设计提供理论基础。
Magnetically suspended rotor micro-gyro (MGELR) is a new type of angular rate sensor that has the same working mechanism as a conventional mechanical gyroscope. MGELR is expected to become a high-precision micro-gyro. For MGELR, stable rotor suspension is extremely important. In this paper, the stable suspension of micro-rotor has been comprehensively studied. The influences of the coil, rotor diameter, current amplitude, flying height and other factors on the suspension stability of micro-rotor are analyzed in detail. The paper presents boundary effect theory to explain the lateral force caused by micro-rotor eccentricity. The test results further demonstrate the correctness of the analysis. The article concludes that the conditions of stable suspension should be satisfied. The research content of this article provides the theoretical basis for the structural design of MGELR.
