With high elevation in magnet prices in recent times, switched reluctance machine (SRM) are gaining importance, due to the simple and rugged construction, low cost, and ability to operate over a wide speed range at constant power. SR machine operates due to the variable reluctance in the air gap, hence displays a highly nonlinear inductance behavior. This makes it impossible to carry out predictions that are accurate with liner formulations. Consequently, it becomes necessary to use the finite element method (FEM), which can handle nonlinear magnetic properties in material and minute geometry and also transient currents. This paper will discuss the virtual modeling and verification procedure established for SR machine to confirm the dynamic drive characteristics including the losses in the machine, at different switch timing w.r.t. operating speed.
