The linear and non-linear FE-based model of a three phase wound rotor induction machine is presented. The effect of stator and rotor currents on the self and mutual inductance is considered. The mathematical representation of the machine in presence of saturation is developed. The calculated model is compared with a simple d-q model, full FE-model, and a linear FE-based phase variable model. The calculated result shows a good match in accuracy with full-finite element model and in run-time with the d-q model.
