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.

Rotor for asynchronous electrical machine with non-through shaft and associated electrical machine

A magnetic mass of an electric machine rotor extending along a longitudinal axis and comprising a plurality of housings, each housing being able to receive a respective electrically conductive bar. The magnetic mass further comprises, on at least one portion of its length along the longitudinal axis, at least one opening extending radially from one of the housings and opening outwards along a radial direction, substantially perpendicular to the longitudinal axis.
