Abstract :
This paper presents an analytical method for the calculation of magnetic field distribution, electromagnetic performances and equivalent circuit parameters of multiphase double cage rotor induction motors in healthy and broken bars condition. The proposed static model takes into account stator and rotor slotting and stator and rotor tooth-tips. A 2D exact complex analytical solution of magnetic field distribution is established. It involves solution of Poisson´s, Laplace´s and Helmholtz´s equations in stator slots, airgap and rotor conductive bars regions respectively. Obtained exact analytical results are verified with those issued from static complex finite element method (Fem).
