A coaxial magnetic gear with Halbach permanent-magnet arrays / Linni Jian in IEEE transactions on energy conversion, Vol. 25 N° 2 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 2 (Juin 2010) . - pp. 319 - 328 Titre : A coaxial magnetic gear with Halbach permanent-magnet arrays Type de document : texte imprimé Auteurs : Linni Jian, Auteur ; Chau, K. T., Auteur Année de publication : 2010 Article en page(s) : pp. 319 - 328 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : finite  element  analysis;  gears;  magnetic  fields;  permanent  magnets;  rotors;  torque Résumé : This paper proposes a coaxial magnetic gear that offers higher torque density, lower cogging torque, and lower iron losses than its counterparts. The key is to newly employ a Halbach permanent-magnet (PM) array to constitute the PM poles in the inner rotor and a partial Halbach array (two segments per pole) for the outer rotor. The corresponding magnetic field distributions, torque transmission, and torque ripples are analytically discussed. Then, the corresponding performances are quantitatively assessed by using the finite-element method.
