摘　　要：双凸极电机中由于转子偏心而产生不平衡电磁拉力,对电机的电气性能有较大影响。研究电磁拉力的计算原理,通过ANSYS编程对电机在不同转子角度下的电磁拉力进行分析,得到了电磁拉力随转子位置以及励磁电流变化而产生的变化规律,并在此基础上得到电机该状态下的电磁转矩。文章通过实验验证了该计算方法的准确性,对双凸极电机设计具有较大的参考意义。Displacement of rotor of doubly salient electro-magnetic motor results in unbalanced electromagnet pulls. The calculation principle of electromagnet force was studied and analyzed in different rotor angle through ANSYS. The change rule of electromagnetic force varies with the different rotor position and exciting current was got. Electromagnetic torque in this situation was also obtained. The experiment proves the accuracy of this method and it has significance for de-sign of doubly salient electro-magnetic motor.
