Abstract :
The stator or rotor faults don´t have important percentage compared to bearings faults. For this reason, it´s necessary for us to worry about this kind of faults. The detection of this failure has been given by several methods. To progress this approach, we propose an analytical model for the diagnosis of induction motor. This paper presents a new precise model for the calculation of inductances in three-phase squirrel cage induction machine. This calculation is done under outer raceway defect. This paper determines a particular geometrical model under the bearing fault conditions and evaluates the inductances. We will investigate the effects of slots in rotor and stator. Rotor asymmetries lead to the change of winding function theory which will be transformed into the modified winding function that influences the inductances due to these conditions.
