Abstract

L'invention concerne un dispositif (1) pour convertir de l'énergie électrique en énergie mécanique et/ou vice-versa, en particulier un moteur à gaine pour une pompe de recirculation, comprenant un rotor (2) tournant autour d'un axe de rotation (10) et un stator (4), le stator (4) présentant une paire de pôles avec enroulements polaires (12, 22; 14, 24; 16, 26). L'invention est caractérisée en ce que le dispositif présente des pièces polaires (70, 72) formées séparément d'une culasse statorique (40) de préférence de forme annulaire, en ce que les enroulements polaires (12, 22; 14, 24; 16, 26) de la paire de pôles sont enroulés en continu sur des bobines d'excitation (44, 46) formées par un corps d'enroulement (42) au moyen d'une machine d'enroulement en couches peu onéreuse et au fonctionnement fiable, par l'intermédiaire d'un segment de liaison (18; 20; 28) de l'enroulement s'étendant au moins en partie radialement par rapport à l'axe de rotation (10), et sont reliés électriquement les uns aux autres sans interruption, et en ce qu'après l'enroulement, les pièces polaires (70, 72) sont insérées dans les bobines d'excitation (44, 46) et amenées radialement vers l'extérieur en contact avec la culasse statorique (40) comprenant radialement du côté extérieur les pièces polaires (70, 72). L'invention concerne également un corps d'enroulement (42) pour un tel dispositif (1) et un procédé de fabrication d'un tel dispositif (1).
