Abstract: 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.
