Abstract

L'invention concerne un alternateur hybride composé d'un stator (702) dans lequel tourne un rotor (710), ces deux éléments étant séparés par un entrefer. Le noyau du rotor comporte plusieurs pôles magnétiques (716) de polarité alternée positive et négative. Ces pôles magnétiques comprennent une pluralité de pôles d'aimants permanents (716a, 716b) et une pluralité de pôles électromagnétiques (716). Chaque pôle d'aimant permanent est défini par un aimant permanent (718). Les pôles des aimants permanents sont divisés en deux groupes diamétralement opposés. L'alternateur hybride comprend également un régulateur de tension termovariable qui assure la protection contre les surchauffes, tout en permettant à l'alternateur de dépasser sensiblement sa capacité nominale pendant de courtes périodes, ou lorsque la température ambiante est basse.
