Abstract

Selon les revendications du brevet cité, cette addition est double. Premièrement elle précise et complète la façon de calculer et de dessiner les dents de transfert, notamment en vue d'obtenir une force électromotrice sinusoïdale pure et un taux de couverture élevé. Deuxièmement elle décrit un dispositif nouveau, plots compensateurs et écran magnétique integré au rotor et permettant d'atténuer ou supprimer les effets nuisibles de la réaction d'induit dans les machines, objet du brevet principal, en compensant la variation de réluctance provoquée par le passage de la denture du rotor sur l'armature d'induit.
