This paper proposes the use of the S-Transform applied to the stator currents as a method for diagnosing the occurrence of rotor electrical fault (broken bars or faulty rotor windings) in induction motor. Induction motor stator currents are first measured and recorded. Then, the S-Transform is applied to the obtained currents in order to get a specific pattern that allows the identification of the rotor fault. Simulation and experimental results, for both a healthy motor and a motor with a rotor electrical fault, are presented in order to show the effectiveness of the proposed method.
