Abstract

Machine électrique d’aéronef à transfert thermique amélioré au moyen d’un matériau à changement de phase et procédé associé Procédé de protection des bobinages d’un échauffement excessif dans une machine électrique d’aéronef comprenant un stator (12) et un rotor (14) configurés pour être entrainés en rotation l’un par rapport à l’autre, le stator comportant une pluralité d’encoches (120) recevant une même pluralité ou non de bobinages, le procédé comportant les étapes successives suivantes : insertion d’un isolant électrique (16) dans les encoches ou sur les dents du stator, mise en place des bobinages (18) dans les encoches ou sur les dents du stator, coulée d’un matériau à changement de phase (20) dans les encoches ou sur les dents munies des bobinages, l’isolant électrique formant un moule de coulée. Figure pour l’abrégé : Fig. 1.
