An analytical model of switched reluctance machines

An analytical model is introduced to describe switched reluctance machines (SRM). The nonlinear function of flux linkage depending on the winding current and rotor position is considered to be composed by three components: aligned and unaligned flux linkages, and an angular function, where the two flux linkages are only determined by phase current, and the angular function depends only on the rotor position. Examples of the application of this model in simulating the phase current, calculating the instantaneous torque and estimating the rotor position are presented. The results are compared with measurements.
