Ventilation system of turbine generator and radial flow cooling rotor

The stator duct number and section width of the developed generator are optimized to minimize temperature difference along stator bars, which enables to get rid of windage loss due to reduced gas flow. The radial flow cooling system is adopted on the developed generator for effective cooling of rotor and stator coils in order to reduce the windage loss. The area of subslot, radial duct pitch and ventilation path of the core end are optimized.
