Abstract
A simplified static excitation system for a fluid-cooled dynamoelectric machine comprises a potential source excitation winding disposed in the stator slots, the winding being responsive to the fundamental frequency of the generator air-gap magnetic flux. The excitation system further comprises transformer means coupling the excitation winding to rectification means which is coupled to the rotating field windings so as to provide direct electric current thereto. The transformer means is preferably disposed within the cooling fluid of the machine.
