Abstract:
A method of manufacturing a generator comprising the steps of:fabricating a stand-alone inner frame module having a central opening defining a generator frame axis;providing a support plate at each of the opposite ends of said inner frame module having an opening defining part of said central opening;installing through at least one of the openings of said support plate and into said inner frame module a stator core including laminations and windings;fabricating a stand-alone drive end cap module and a stand-alone exciter end cap module each having a central opening for receiving a generator rotor, each end cap module comprised of an end cap frame having a pedestal support integrally formed with and mounted on said end cap frame for mounting and supporting a pedestal bearing;fabricating the inner frame module and each end cap module such that said end cap module openings are smaller in diameter than the diameter of said central opening through said inner frame module and the diameters of said support plate openings at opposite ends of said inner frame module;securing said end cap modules to said inner frame module at opposite ends thereof subsequent to the installation of said stator core in said inner frame;subsequent to securing said end cap modules to said inner frame, inserting the generator rotor through the smaller diameter end cap module openings and the inner frame opening; andsubsequent to inserting the rotor, supporting the rotor at opposite ends on the pedestal bearings.
