Effect of the variation of the rotor impedance with slip on the performance of single-phase excited three-phase induction motors / Abu-Elhaija, W. S. in IEEE transactions on energy conversion, Vol. 25, N° 4 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 4 (Décembre 2010) . - pp. 1010 - 1020 Titre : Effect of the variation of the rotor impedance with slip on the performance of single-phase excited three-phase induction motors Type de document : texte imprimé Auteurs : Abu-Elhaija, W. S., Auteur ; Muetze, A., Auteur Année de publication : 2011 Article en page(s) : pp. 1010 - 1020 Note générale : energyc onversion Langues : Anglais (eng) Mots-clés : Capacitor  motors;  electric  impedance;  induction  motors;  machine  theory;  rotors Résumé : Certain conditions can require a three-phase induction motor to be operated on a single-phase supply. The proper sizing of the required auxiliary capacitor to meet certain criteria has been discussed, both for constant and for electronics-based variable capacitors. Generally, constant motor parameters are assumed. However, as of a certain motor size, and hence, slot depth, the rotor impedance varies with slip because of skin effect. In this paper, we discuss the influence of this phenomenon on the motor performance, focusing on the peculiarities of single-phase operation. The analysis not only includes Y- and Δ-connected motors but also a third type of connection that we refer to as “Y-segregated leg-connection” and that has not yet found much attention.
