First, the stator currents data pattern is used as a preliminary diagnosis. Secondly the extended Park\u2019s vector approach (EPVA) is also used. An elliptic pattern and a 2nd harmonic component are obtained by these two methods respectively. These signatures in other researches are often considered as direct and accurate indicators of a stator winding fault. This similarity leads to uncertainty in the detection of the fault, which makes imperative\u00a0 the use of complementary technique. The focus on the 2nd harmonic of the supply frequency (<em>2.fs<\/em>) in the torque spectrum (THA technique) has shown its effectiveness as good indicator of voltage unbalances. Therefore, to distinguish between these faults, the THA is considered as the ideal tool for this purpose.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words: <\/strong>induction motors, stator voltage unbalance, fault diagnostics, stator currents pattern, EPVA, THA<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Num\u00e9ro de la revue:\u00a034 Auteurs: Nadir Benamira1, Mohamed Faouzi Rachedi2, Slimane Bouras3, Samir Kerfali4 &amp; Ahmed Bouraiou5 1,2 Electromechanical systems laboratory, department of electromechanical engineering, Badji Mokhtar-Annaba Uuniversity, P.O.
