<p>A ventilated rotor (1) of a high-power turbogenerator for the production of electricity has a shaft (2) extending along an axis (A); a plurality of axial slots (7) obtained in the shaft (2); a plurality of conductor bars (14) arranged at least partly in the slots (7) ; a plurality of axial channels (18) suitable for ventilating the conductor bars (14) ; a plurality of subslots (9) , each of which is arranged below a slot (7) to distribute a ventilating gas; a plurality of axial portions travelled over by respective flows of ventilating gas along each axial channel (18);and at least one radial channel (26), which is intended to convey directly the ventilating gas from the subslot (9) to the outer surface of the rotor (1) via the conductor bars (14) and is arranged between two consecutive and adjacent axial portions of an axial channel (18) .</p> |
