Nonlinear magnetic circuit analysis for a novel stator doubly fed doubly salient machine

A novel stator doubly fed doubly salient (SDFDS) machine is proposed, and a nonlinear magnetic circuit (NMC) model is developed for the analysis of the SDFDS machine. Based on the NMC model, the static characteristics of an 8/6-pole SDFDS machine are analyzed using specific permeance calculations, in which the interaction between field and armature currents as well as the magnetic saturation are taken into account. The proposed NMC modeling is verified using both finite-element analysis and experimentation.
