This paper presents the Finite Element Method technique for predicting performance of Induction motor having Electric and Magnetic asymmetry for rotor cage due to some broken rotor bars. The motor parameters like magnetic vector potential, flux density, surface currents have been determined very precisely by carrying out two dimensional quasi static, transient analysis and by using one of the latest FEM tool i,e. COMSOL Multiphysics.

The required detailed magnetic field distribution analysis can be carried out for further evaluation of motor’s operational behavior. The simulation results have been validated experimental results of the model.
