摘要： The rotor (4) for rotary electric machine (1) comprises a magnetic mass (5) clamped between two compaction elements (6, 7), and tie rods (13) passing through the magnetic mass and connecting the two compaction elements, at least a first compaction element comprising as many through holes (15) as tie rods, each through hole of the first compaction element comprising a counterbore (16) on one side opposite to the side in contact with the magnetic mass (5), each tie rod passing through a different through hole of the first compaction element and being fixed in the said through hole by a fixing element (17) of the first compaction element logged in the said counterbore, characterized in that each fixing element (17) and the associated counterbore (16) cooperate so that each fixing element is in contact with the counterbore in a radial direction of the rotor.
