Abstract
In a gas-cooled electric machine the cooling-gas supply and removal in the cavity between the laminated stator body and housing is arranged so that the heated cooling gases from the central section of the machine are supplied through separate cooling-gas lines to the ends of the machine and, consequently, to the coolers. In this manner, the individual volumetric flows through the individual zones (I, II, III) of the machine can be partitioned so that an equalization of the temperature level in the longitudinal direction of the machine is achieved.
