Abstract
A variable pressure electric generator, including 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 stator frame arranged to fixedly support the core and rotationally support the rotor; a gas cooling system that circulates a cooling gas within the generator; a pressurizing system that operatively pressurizes the cooling medium to a maximum pressure of 2 bar relative to atmospheric pressure, wherein the pressurizing system continuously determines the cooling medium pressure based upon operational requirements; and a low pressure frame that surrounds a plurality of the rotor and an entirety of the core and stator windings, the frame configured to operatively contain an internal pressure of 2 bar relative to atmospheric pressure.
