Analytical approach of the rotor broken bars effects on the induction machine behavior

This article presents a complete analytical description of the rotor broken bars effects on the induction machine behavior, for diagnosis purposes. The stator current and the electromagnetic torque are important elements to study in order to define the behavior of the healthy induction machine and can provide a model-based approach of the rotor bars fault detection in induction machine. An experimental validation of the proposed analytical approach is provided.
