摘　　要：以10 kV-3 000 kW-2极高压高速电动机为例,对转子偏心情况下电机转轴的静力学进行分析。对单边磁拉力的计算分别采用分析法和有限元法,并针对带有轴向通风槽的转轴挠度进行计算。然后通过ANSYS Workbench有限元仿真软件对转轴进行静力学仿真分析。在保证计算精度的基础上,可使用分析法。这为高压高速电动机单边磁拉力和转轴的静力学分析提供了参考。Using a 10 kV-3 000 kW-2 pole high-voltage high-speed motor as an example,the statics of the shaft were analyzed under the rotor eccentricity.An analysis method and a finite element method were proposed for the unilateral magnetic force,and the deflection of the shaft with axial ventilation slots was calculated.Then,the statics of the shaft were analyzed by ANSYS Workbench finite element simulation software.The analysis method could be used on the basis of ensuring the calculation accuracy.A reference for the unilateral magnetic force and the static analysis on the shaft of the high-voltage high-speed motor was provided.
