摘　　要：为高速磁浮列车设计了一种相位检测传感器,针对实际应用中悬浮间隙波动会影响相位检测的问题,提出了利用采样信号幅值监测悬浮间隙,并依据悬浮间隙对采样信号进行归一化处理来消除间隙波动影响的方法。通过实验证明了该方法的有效性。To meet the high precision phase detection request of high speed maglev train tractive system, a phase detection sensor is designed. Because the phase detection is affected greatly by change of suspend gap in practice, a method of detecting the gap by sample signal and normalizing phase signal by the gap is presented. It is proved to be valid by experiment.
