摘要： Described is a large, thin frame gas cooled electric generator for power generation, having a gas cooled rotor arranged along a centerline of the generator; a gas cooled core arranged coaxially and surrounding the rotor; a plurality of coils arranged within the core; a support frame arranged to fixedly support the core and rotationally support the rotor; a gas cooling system configured to circulate a cooling gas within the generator; a pressurizing system configured to variably pressurize the cooling gas to a maximum pressure of one bar relative to atmospheric pressure; and a pressure boundary member that surrounds a portion of the rotor and an entirety of the core and stator windings, the frame configured to operatively contain an internal cooling medium pressure of two bar relative to atmospheric pressure.
