The paper attempts to evolve a model for determining the core loss of a switched reluctance motor (SRM), widely used as a drive for propulsion in electric vehicles (EV). The core loss forges to be one of the key factors in deciding the performance of the drive motor and requires extensive considerations to minimize it. The SRM offers promising characteristics to be suitable for the propulsion of a vehicle owing to its outstanding merits and use of steel lamination as the core material. The study involves the use of 2D-FEM analysis on a SRM with non-oriented electrical steel possibilities and brings out a strong correlation between the material flux density and permeability. The results relate the variation of motor core loss for different materials and exhibit the effect on core loss. The model manifests an empirical approach to the calculation of core loss besides establishing the strong relationship among the parameters of the magnetic material.
