Abstract

L'invention concerne un moteur électrique de type à boîtier refroidi, qui est refroidi par immersion du boîtier d'une carcasse de stator (2) dans un réfrigérant. Une couche d'élément thermiquement conducteur (15) est formée dans un dégagement (13) entre l'arrière d'un noyau de fer de stator (1), qui est obtenu en amenant une plaque d'acier électromagnétique (11) en contact avec la face de paroi interne de la carcasse de stator (2) pour fixer la plaque dans l'état stratifié, et la face de paroi interne de la carcasse de stator (2). La couche d'élément thermiquement conducteur (15) est faite principalement d'une feuille de graphite, et peut être montée sur soit l'arrière du noyau de fer de stator (1) soit la face de paroi interne de la carcasse de stator (2). Le dégagement (13), qui pourrait sinon exister entre l'arrière du noyau de fer de stator (1) et la face de paroi interne de la carcasse de stator (2) de sorte qu'il obstruerait le rayonnement de la chaleur dégagée dans le fonctionnement par le noyau de fer de stator (1) et transférée à la carcasse de stator (2), abaissant ainsi les performances de refroidissement d'un enroulement de stator (3), peut être supprimé pour obtenir le moteur électrique du type à boîtier refroidi ayant une excellente performance de refroidissement.
