FIELD: electromechanical engineering; gas-cooled turbogenerators. SUBSTANCE: end portion of rotor field winding is cylindrical in shape and space between inner surface of coils and rotor shaft is divided by means of distributing members into even number of equal compartments, each second compartment being divided by additional partition into two parts; first part of divided compartment abuts against rotor shaft and second one, against inner surface of coils. EFFECT: improved cooling conditions of rotor. 1 cl, 3 dwg
