摘要：电励磁双凸极发电机的仿真常采用的有限元方法结果精确，但耗时长。简化的电感分段线性化方法则会造成大的仿真误差。本文分析了四相电励磁双凸极电机相绕组互感相比自感可以忽略的特性，利用四相电枢绕组的对称性，得到四相双凸极电机的相磁链模型，进而建立四相双凸极发电机的仿真模型。通过与有限元仿真以及试验结果的对比，验证了本文方法的快速性与准确性。

Abstract: Finite element method is usually adopted to simulate a doubly salient machine. However, it is a time-consuming process. The mutual inductances between two phases can be neglected when comparing to the self-inductance. The simulation method based on the phase flux model was proposed in this paper. The flux model of phase A was setup according to different field currents and phase currents. Then the four-phase doubly salient machine can be obtained by the symmetry of the phases. The flux model method was compared to the finite element method and was verified by the experimental results.
