摘要： A non-reversible electrical machine with gas cooling comprises a body (6) with built-in gas coolers (7), said body (6) accommodating a stator winding with end connections (5), a rotor (1) whose shaft carries fans (2) having exhaust chambers (8) and pressure chambers (9), and a stator core (3) with radial vent ducts (4) being divided, together with a space between it and the body (6), into segments (11) which are associated with the exhaust chambers (8) of the fans (2), and also into the same number of alternating segments (12) which are associated with the pressure chambers (9) of the fans (2). The radial vent ducts (4) in each area of the stator core (3), adjoining to the end connections (5) of the stator winding are separated from the remaining radial vent ducts (4) by two cylindrical partitions (14 and 18). One partition (18) is positioned in a gap (16 ) between the rotor (1) and the stator core (3) and forms together with the inner surface of the stator core (3) an annular cavity (19) which is associated with a respective exhaust chamber (8) of the fan (2). The other partition (14) is positioned in a space between the stator core (3) and the body (6) and forms together with the external surface of the stator core (3) an annular cavity (15) communicating with the segments (12) which are associated with the pressure chambers (9) of the fans (2). Both cavities (15 and 19) are associated with each other through the radial vent ducts (4) in the area adjoining the end connections (5) of the stator winding.
