A schwarz–christoffel-based analytical method for electric machine field analysis / O'Connell, T.C. in IEEE transactions on energy conversion, Vol. 24 N° 3 (Septembre 2009)  

Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 24 N° 3 (Septembre 2009) . - 565 - 577 Titre : A schwarz–christoffel-based analytical method for electric machine field analysis Type de document : texte imprimé Auteurs : O'Connell, T.C., Auteur ; Krein, Philip T., Auteur Année de publication : 2010 Article en page(s) : 565 - 577 Note générale : Energy Conversion Langues : Anglais (eng) Mots-clés : Asynchronous machines--Electric machine--Analysis computing--Magnetic materials Résumé : With the recent increase in the availability and widespread use of inverters, exotic rare earth permanent-magnet materials, and low-cost, precision manufacturing, new design tools are needed to aid engineers in designing state-of-the-art electromechanical systems. For this purpose, recent software advances allow a reexamination of previously intractable analytical solutions to the boundary value problems governing these systems. This paper presents an analytical field analysis method for electric machines utilizing the Schwarz-Christoffel transformation and implemented with the SC Toolbox software package. With the method, general 2-D electric machine cross sections with linear magnetic materials are analyzed. The method is then extended using superposition to analyze wound-rotor induction machines in the time domain. With this extension, numerous machine geometries, stator excitations, winding and slot harmonics, and torque ripple can be examined. Note de contenu : Bibiogr.
