1. Rotating electric machine comprising a stator made of magnetic stator laminations (16, 49) threaded onto longitudinal rods (11, 12, 13, 14; 48) parallel to the axis of the machine and clamped between two end plates (17 and 18; 50 and 51), and end chambers (57 and 65) which are also fixed by the said longitudinal rods (11, 12, 13, 14; 48), characterised in that at least one longitudinal rod (11, 12, 13, 14; 48) presents several journals (33-40; 56, 64, 73, 74) with different diameters, arranged on one side and on the other with respect to the median plane of the machine, and has at each reduction in diameter external threads for corresponding nuts (21, 22, 23, 24; 52, 53; 58, 66), and in that on the largest diameter of the said longitudinal rod (11, 12, 13, 14; 48) are threaded the magnetic stator laminations (16, 49) and the end plates (17 and 18; 50 and 51) held in compression by nuts (21, 22, 23, 24; 52 and 53) screwed onto the corresponding threaded journals, and in that the end chambers (57 and 65) are firmly fixed to the said longitudinal rod (11, 12, 13, 14; 48) by threading onto the intermediate diameter journals (33, 34, 35, 36; 56 and 64) and by tightening against the end plates (17, 18; 50 and 51) by means of nuts (58 and 66) and in that the smallest diameters of the longitudinal rod (11, 12, 13, 14; 48) project outside the end chambers (57 and 65) and are shaped to be directly suitable for the fixing or the suspension of the machine. |
