Tubes à rayons X Résumé : This paper presents an analytical approach to shed light on the necessary relationships required for the presence of induction motor diagnosis signatures in the line neutral voltage (the voltage taking place between the supply and the stator neutrals). 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.
