A reconfigurable motor for experimental emulation of stator winding interturn and broken bar faults in polyphase induction machines / Yeh, Chia-Chou in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1005 - 1014 Titre : A reconfigurable motor for experimental emulation of stator winding interturn and broken bar faults in polyphase induction machines Type de document : texte imprimé Auteurs : Yeh, Chia-Chou, Auteur ; Sizov, G.Y., Auteur ; Sayed-Ahmed, A., Auteur Année de publication : 2009 Article en page(s) : pp. 1005 - 1014 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Fault  diagnosis;  induction  motors;  machine  testing;  rotors;  stators Résumé : The benefits and drawbacks of a 5-hp reconfigurable induction motor, which was designed for experimental emulation of stator winding interturn and broken rotor bar faults, are presented in this paper. It was perceived that this motor had the potential of quick and easy reconfiguration to produce the desired stator and rotor faults in a variety of different fault combinations. Hence, this motor was anticipated to make a useful test bed for evaluation of the efficacy of existing and new motor fault diagnostics techniques and not the study of insulation failure mechanisms. Accordingly, it was anticipated that this reconfigurable motor would eliminate the need to permanently destroy machine components such as stator windings or rotor bars when acquiring data from a faulty machine for fault diagnostic purposes. Experimental results under healthy and various faulty conditions are presented in this paper, including issues associated with rotor bar-end ring contact resistances that showed the drawbacks of this motor in so far as emulation of rotor bar breakages. However, emulation of stator-turn fault scenarios was successfully accomplished.
