Induction motor equivalent circuit including the stray load losses in the machine power balance / Boglietti, A. in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 796 - 803 Titre : Induction motor equivalent circuit including the stray load losses in the machine power balance Type de document : texte imprimé Auteurs : Boglietti, A., Auteur ; Cavagnino, A., Auteur ; Ferraris, L., Auteur Année de publication : 2008 Article en page(s) : pp. 796 - 803 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Electric impedance  equivalent circuits  harmonics  losses  machine theory  rotors  squirrel cage motors  stators Résumé : In this paper, the stray load losses due to the air gap spatial harmonics effects on the rotor squirrel cage are considered and a simplified induction motor equivalent circuit able to include them in the machine power balance is reported. In the proposed model, an additional resistance appears in series with the stator impedance. This additional parameter has been defined on the basis of power balance considerations applied to the induction motor classical theory. The complete theoretical analysis together with the guidelines to measure the equivalent circuit parameters are reported in detail. Finally, the proposed approach has been experimentally verified using five total enclosed fan cooled induction motors.
