Abstract

La présente invention concerne un rotor de machine électrique tournante, notamment pour machine synchro-réluctante. Le rotor comprend un moyen de ventilation (1) de fluide et un corps de rotor fixé à un arbre de rotation. De plus, le moyen de ventilation (1) est fixé au rotor et comprend une plaque annulaire (2) avec des ouvertures (5) pour le passage du fluide. La plaque annulaire (2) comprend en outre des ailettes (4) s’étendant depuis la périphérie du rotor vers l’arbre de rotation. Figure 1 à publierThe present invention relates to a rotor for a rotating electrical machine, in particular for a synchro-reluctant machine. The rotor includes a fluid ventilation means (1) and a rotor body attached to a rotating shaft. In addition, the ventilation means (1) is fixed to the rotor and comprises an annular plate (2) with openings (5) for the passage of the fluid. The annular plate (2) further comprises fins (4) extending from the periphery of the rotor towards the rotation shaft. Figure 1 to publish
