摘要
双凸极电机是一种新型的电机 ,它的电感参数对分析它的基本理论和运行特性至关重要。本文对三相电励磁的双凸极电机建立变网络等效磁路模型。在考虑励磁磁场和电枢磁场相互作用以及磁路饱和的基础上 ,利用该方法可以计算在任意转子位置、任意电枢电流、任意励磁电流下任一绕组自感和绕组之间互感。该计算结果和电磁场有限元分析结果进行比较 ,验证了该方法的正确性。最后 ,得到了不同情况下该电机电感参数变化的一般规律。
Doubly salient motors is a newly invented motor of which the inductance parameters are really important to its performance analysis.Based on equivalent magnetic circuit model,the self inductance and mutual inductance of each coil can be derived easily in arbitrary rotor position?arbitrary exciting current and armature current of each phase,in which the interaction between the exciting current field and the armature current field,as well as the magnetic saturation are taken into account.There is a good agreement between the results of the nonlinear varying network magnetic circuit method and finite element analysis.Finally the general rule of the inductance parameters under different circumstances is presented in this paper.
