Abstract: In this paper, a novel magnetic circuit network model is proposed for flux calculation on switched reluctance machines (SRM) of double saliency. Specifically, the airgap reluctance is modeled by a topology of paralleled magnetic paths that only depends on geometry and rotor position, while magnetic saturation on poles is modeled by a simple lookup approach. Such network is featured by allowing magnetic coupling effect from multiple phases. The flux linkage and torque generation considering the coupling can be calculated in a fast and accurate way without limit of power density or rotating speed.
Keywords: Switched reluctance machine, magnetic equivalent circuit, phase coupling, magnetic saturation
