Abstract

L’invention concerne une machine (1) électrique polyphasée comprenant un stator comprenant une pluralité d'enroulements réunis à au moins un point neutre, et un dispositif (4) de refroidissement équipé de moyens (8, 9) de liaison fluidique pour permettre un raccordement du dispositif (4) de refroidissement à un système d'alimentation en fluide de refroidissement.Le dispositif (4) de refroidissement est formé par un conduit (41) de circulation de fluide de refroidissement, en forme d'anneau ouvert, les moyens (8, 9) de liaison fluidique du dispositif (4) de refroidissement sont disposés sur ledit conduit (41), de part et d'autre de l'ouverture (5) de l'anneau, et le dispositif (4) de refroidissement est électriquement conducteur et constitue le point neutre du stator. Figure pour l’abrégé : Fig.2The invention relates to a polyphase electric machine (1) comprising a stator comprising a plurality of windings joined together at at least one neutral point, and a cooling device (4) equipped with fluidic connection means (8, 9) to allow a connection of the cooling device (4) to a cooling fluid supply system. The cooling device (4) is formed by a cooling fluid circulation conduit (41), in the form of an open ring, the means fluid connection (8, 9) of the cooling device (4) are arranged on said duct (41), on either side of the opening (5) of the ring, and the cooling device (4) is electrically conductive and constitutes the neutral point of the stator.
