Abstract

A system comprising a rotor (11) for a rotating electric machine and bearings maintaining the rotor in rotation, the rotor being a non-through shaft comprising two half-shafts (13) holding tightly a cylindrical magnetic mass (14) comprising a plurality of stacked laminations, circumferential tie rods (15) distributed uniformly over a first diameter of the magnetic mass so as to keep the magnetic mass compacted between the half-shafts is proposedThe rotor further comprises polar tie rods (29) distributed in an angular sector of each pole with respect to a rotation axis of the rotor so as to keep the magnetic mass compacted between the half-shafts and to stabilize the rotor in rotation according to the bearings, each angular sector comprising the same number of polar tie rods.
