Improved modeling of switched reluctance motor including mutual and saturation effects

An advanced nonlinear model of four phase switched reluctance motor (SRM) has been developed. The proposed model takes account of the existence of saturation and mutual inductances. A magnetic data based on the finite element method (FEM) has been generated to check the case of single and doubly energized phases. In this data, the self and mutual inductances and the electromagnetic torque have been computed for wide range of current levels and rotor positions. The present predictions are used as look-up tables in order to guess the behavior of the SRM. Finally, as a demonstration, simulation results are presented to validate the proposed model in both single and doubly excited phase´s mode.
