Modular generator frame construction

摘要

The generator frame includes an inner frame module having openings at opposite ends sufficiently large to permit installation of various elements of the stator core, including the laminations and windings. Separate end cap modules having openings for receiving the rotor, as well as integral pedestal supports, are fabricated separately from the inner frame module and later secured, for example, by bolting, to the inner frame. Upon installation of the rotor, a packaged generator is afforded which can be bolted directly to a foundation at the installation site without an intervening base assembly.
