ROTOR POUR MACHINE ELECTRIQUE ASYNCHRONE A ARBRE NON TRAVERSANT ET MACHINE ELECTRIQUE ASSOCIEE

Le rotor (4) pour une machine électrique tournante asynchrone à arbre non traversant comprend une masse magnétique cylindrique (7) enserrée entre deux brides de fixation (5a, 6a) de deux demi-arbres (5, 6). Il comprend des moyens de refroidissement aptes à refroidir le rotor. Provided is a rotor for an asynchronous rotary electrical machine with non-through shaft that includes a cylindrical magnetic mass gripped between two mounting flanges of two half-shafts, a cooling means capable of cooling the rotor and conductive bars housed within the magnetic mass and distributed substantially uniformly over a diameter of the magnetic mass. The cooling means includes, for each conductive bar, at least one cooling channel, opening onto the conductive bar according to an axial direction and located within the magnetic mass and at least one through hole arranged within each conductive bar in such a way that the cooling channel communicates with at least one hole arranged on the outer periphery of the magnetic mass.
