Modeling of the induction machine for the diagnosis of rotor defects. Part I. An approach of magnetically coupled multiple circuits

The authors develop the squirrel cage induction machine model for the diagnosis of defects from an approach of magnetically coupled multiple circuits. The generalized model is established on the base of mathematical recurrences. The winding function theory is used for determining the rotor resistances and the inductances in the case of n-broken bars and broken end-ring. Simulation results, in Part. II of this paper, confirm the validity of the proposed model.
