Abstract

L'invention concerne un ensemble rotor pour une machine à flux axial qui peut inclure au moins un aimant et des première et deuxième structures de support. La première structure de support peut être conçue pour avoir l'aimant ou les aimants fixés à celle-ci et pour assurer un chemin de retour de flux à l'aimant ou aux aimants. La deuxième structure de support peut être conçue pour être fixée à la première structure de support afin de permettre que le couple soit transféré entre l'aimant ou les aimants et la deuxième structure de support par le biais de la première structure de support, et peut en outre être conçue (A) pour être fixée à un arbre rotatif de la machine à flux axial, ou (B) pour servir de culasse de sortie ou d'entrée de la machine à flux axial.
