We propose a simple equivalent circuit and mathematical model for the magnetic system of switched-reluctance machines (SRMs). The saturation effect in the stator yokes is taken into account, and phase inductance is represented as a function of phase current and reluctance in the air gap. We also propose a simple method for measurement and evaluation of the parameters of SRMs based on the model and present results of numerical simulations and real experiments on an SRM as an autonomous single-phase generator.
