摘要
基于永磁电磁轴承(PMEB),从控制线圈两端提取因磁通随转子位移变化的电感电压(电流)作为反馈信号,以构成闭环控制的自检测磁悬浮轴承系统。建立系统的数学模型,分析自检测控制系统的检测原理,对该系统的试验结果进行分析。
Drected toward the PMEB （ Permanent Magnet Electric Bearing）, extracting the induction voltage （ current ） from the both ends of control magnet coil which is obtained from the magnet flux changing with the displacement. Through full-wave rectification, the feedback voltage signal changed into voltage signal which is in proportion to rotor displacement, and then change this voltage signal into control signal to adjust the rotor displacement.
