Modeling, simulation, and analysis of stator windings of induction machines in high frequencies

The paper offers a modeling method for obtaining the broad band impedance response of three phase induction machines for different measuring situations. Our motivation for this work is the contributions of inverter driven machines operating at variable speeds on the idea of research. Variable capacitance and core loss resistance are viewed as important parameters in the modeling. The equivalent circuits for three measuring configurations are discussed and derived. Simulation and experiment results for different measurements are compared to verify the validation of the models. Parameters identification and sensitivity analysis in the model are conducted to obtain more accurate parameters and their behaviour in frequency response.
