  • ELECTRODYNAMIC MACHINE COMPRISING A COOLING DUCT
    Publication number: 20170264169
    Abstract: A turbine generator of the reverse-flow type having a rotor winding and a stator winding and a cooling duct, wherein the cooling duct is designed as a diffuser. The diffuser is designed such that a device is arranged on an internal cooling duct wall, which device prevents the flow of the cooling medium from stalling, leading to an improved, more uniform flow to a cooling apparatus.
