在重排理论的基础上，对于永磁直线同步电机在空载和变载两种情况下的电机动子相电流进行了时频分析，分析的结果表明重排理论能够清晰地反映永磁直线同步电机在运行过程中动子相电流的时频分布，通过和快速傅里叶变换的对比，很好地解释了动子运动过程中电流频次的变化。

On the basis of rearrangement theory,this paper has analyzed time-frequency distribution of mover phase current in the two cases of no-load and variable load for permanent-magnet linear synchronous motor. The analysis results show that rearrangement theory can describe time-frequency distribution of mover phase current clearly when permanent-magnet linear synchronous motor is in operation which explained a variety of frequencies of the current in contrast with Fast Fourier Transform.
