Special attention is focused on the effect of both space distribution of rotor bars and rotor dissymmetry on the mechanism of generation of diagnosis signatures with consideration of voltage supply unbalance and speed ripples. Generalized and new formulas are proposed, where we can draw a conclusion on the state of the machine. Simulation and experimental results have shown excellent match with theoretically predicted harmonic components.

On the use of slot harmonics as a potential indicator of rotor bar breakage in the induction machine / Khezzar, Abdelmalek in IEEE transactions on industrial electronics, Vol. 56 N° 11 (Novembre 2009)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper sheds light on the additional harmonic components arising from broken bars fault in the stator line current of an induction machine, which are generalized and analyzed in a different manner than of those given in the literature. Special attention is focused on the effect of both motor slots and rotor dissymmetry on the mechanism of the generation of the different harmonic components with consideration of the unbalance voltage supply and speed ripples effects. Aside from the well-known diagnosis signatures, new ones show up. The simulation and experimental results confirm the aforementioned study.
