Field computation for an axial flux permanent-magnet synchronous generator / Chan, T. F. in IEEE transactions on energy conversion, Vol. 24 N°1 (Mars 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N°1 (Mars 2009) . - pp. 1 - 11 Titre : Field computation for an axial flux permanent-magnet synchronous generator Type de document : texte imprimé Auteurs : Chan, T. F., Auteur ; Lai, L.L., Auteur ; Shuming Xie, Auteur Année de publication : 2009 Article en page(s) : pp. 1 - 11 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Fourier  series;  Laplace  equations;  finite  element  analysis;  machine  theory;  magnetic  fields;  permanent  magnet  generators;  synchronous  generators Résumé : An analytical method to determine the no-load and armature reaction magnetic fields of a single-sided, axial flux permanent-magnet synchronous generator without armature core is presented. Laplace's equation is solved in the rectangular coordinate system to give the scalar magnetic potentials, using a Fourier series method. For computation of the armature reaction field, a multi-current-sheet model is employed in order to account for the distributed nature of armature conductors in the axial direction. Finite element analysis and experimental results on a prototype machine are presented for verifying the accuracy of the proposed method.

Performance of an axial-flux permanent magnet synchronous generator from 3-D finite-element analysis / Chan, T. F. in IEEE transactions on energy conversion, Vol. 25, N° 3 (Septembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 3 (Septembre 2010) . - pp. 669 - 676 Titre : Performance of an axial-flux permanent magnet synchronous generator from 3-D finite-element analysis Type de document : texte imprimé Auteurs : Chan, T. F., Auteur ; Weimin Wang, Auteur ; Lai, L.L., Auteur Année de publication : 2011 Article en page(s) : pp. 669 - 676 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : finite  element  analysis;  machine  theory;  permanent  magnet  generators;  rotors;  stators;  synchronous  generators Résumé : For the first time, this paper presents field computation results and performance of an axial-flux permanent magnet synchronous generator (AFPMSG) based on a time-stepping, 3-D finite-element analysis (3-D FEA). The prototype generator studied has a ferromagnetic outer rotor frame and a totally enclosed design, while a coreless stator armature configuration is used. Based on the machine geometry, a 3-D FEA model is developed in order to determine the principal field components. The flux in the rotor back plate and the transverse flux through the ferromagnetic spacer, which is part of the rotor frame, can both be predicted. A time-stepping, coupled field-circuit approach enables the waveforms and load characteristics of the AFPMSG to be obtained accurately. The computed results are validated by experiments on the prototype generator.
