FIELD: electricity.SUBSTANCE: invention relates to the area of electrical machines with rotary parts. Air-cooled engine generator (10) comprises rotor (34) with shaft (11), which is placed so that it can be rotated around the machine axis (15) whereat the rotor winding (16) is placed, and stator (35) with package (18) of active steel and winding (17) placed in it and covering concentrically rotor winding (16), at that closed air-cooling loop is envisaged, wherein cooling air passes through rotor winding (16) and stator winding (17) radially inside-out, it is cooled in coolers (19) placed outside stator (35) and then returned back to rotor (34).EFFECT: being changed before operation or in process cooling is implemented in a simple way due to the fact that regulated throttling devices are mounted at coolers (19) in order to control volume flow of cooling air in the cooling loop.16 cl, 5 dwg |
