Abstract
Disclosed is an improved life large electric generator comprising a rotor arranged along a centerline of the generator; a core arranged coaxially and surrounding the rotor; a plurality of stator windings 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 liquid cooling system that circulates a cooling liquid to cool the stator windings wherein the cooling ability of the liquid cooling system is a function of a required generator parameter; and a pressure boundary member 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 two (2) bar relative to atmospheric pressure.
