Abstract

The electromechanical interaction in cage induction motors induces additional forces between the rotor and stator. Recently, a linear parametric model was presented for these forces and the model was validated experimentally. The effective identification of the model parameters is crucial, because the electromagnetic system is nonlinear. The aim of this study was to present how to apply the impulse response method to estimate the required parameters. The numerical results show that this method is very effective. In addition, the force model was combined with a mechanical rotor model and the feasibility for electromechanical rotor problems was demonstrated.
