转子是磁悬浮轴承系统旋转机械的核心部件，其性能与系统稳定性及各项技术指标紧密相连。提升转子动态性能已成为当务之急。以磁悬浮开关磁阻电机的磁轴承转子为例，通过普劳尔传递矩阵法和MATLAB强大的绘图功能分别就柔性、刚性两种不同状态下的支承，计算出了该轴系的固有频率及临界转速，并得到了相应的主振型图。

With its high speed, high effiency, the magnetic bearings-rotor system has become the core of modern rotating machinery system, Taking the magnetic bearing rotor of the bearingless switched reluctance motor as an example, by using Prohl transfer matrix method and the drawing function of MATLAB, according to the rigid support and flexible support respectively,the free frequency and critical speed of the spindle system was got,and the relative main vibration model was found.
