Comparative study of two diagnosis methods induction machine

Intensive research efforts have been focused on the signature analysis (SA) to detect electrical and mechanical fault condition of induction machines. Different signals can be used: voltage, current, flux and power. This paper is a comparative analysis of two different diagnosis methods that are used to detect and localize failures in induction motors. The first one is based on leakage flux measurement and the second one is a diagnosis method based on current, electrical power measurement and pattern recognition. A synthesis of two methods will be developed. It mainly concerns rotor faults.
