Description
Summary:In this paper, we build a fast simulation model for the analysis of eccentric induction motor. The self and mutual inductances of the motor windings are calculated with modified winding function method, with slotting effect and core saturation considered for improved accuracy. The calculated inductances are then fed into a coupled circuit model to simulate the dynamics of an eccentric induction motor. Compared with time-stepping finite-element method, the model is much faster for machines under eccentric faulty conditions. The accuracy of the model is validated with experiment measurements, with good match for fault component amplitudes.
