ABSTRACT:
A fluted stator frame for an electric generator is provided. The fluted stator frame has a frame shell, a plurality of flat plates, a plurality of inner frame rings and a plurality of revised axial spring bars. A stator core is connected to the inner frame rings by means of the revised axial spring bars. The inner frame rings are connected to the frame shell by means of the flat plates. Each flat plate is slanted so that the plurality of flat plates are arranged in a truss formation. The spaces between the flat plates and the frame shell define gas flow ducts. The gas flow ducts provide a path for a flow of cooling gas to remove heat from the stator core of the generator.
