In the case of a gas-cooled electrical machine, the effective flow cross-section of the connection from the outer hot-gas chambers to the cooler is provided with an adjustable restrictor device (29, 31; 32, 33). In this way, the splitting of the various cooling-air flows within the machine can be influenced, without intervention in the actual machine, such that equalization of the temperature level in the machine longitudinal direction is achieved.
