Experimental verification of critical-speed increase of single-phase induction machines via winding reconfiguration with solid-state switches / Schraud, J. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 460 - 465 Titre : Experimental verification of critical-speed increase of single-phase induction machines via winding reconfiguration with solid-state switches Type de document : texte imprimé Auteurs : Schraud, J., Auteur ; Fuchs, E. F., Auteur ; Fuchs, H. A., Auteur Année de publication : 2008 Article en page(s) : pp. 460 - 465 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Induction motors  machine windings  power electronics  starting  switching  switching circuits Résumé : The concept of online electronic switching of windings will be applied to a single-phase induction motor with two separate windings with different pole numbers p1 = 4 and p2 = 6 and an auxiliary winding required for starting. During switchover from the low-speed winding to the high-speed winding, and vice versa, lasting less than a few milliseconds, small electrical torque and speed transients occur. Relying on closed-loop speed control, a smooth speed response is measured. This concept is, therefore, applicable to variable-speed drives, where a large speed range is desirable. Test data indicate that a speed-control range from 600 to 4000 r/min is obtainable with a single-phase induction motor.
