Abstract

This paper summarizes the features that must be considered, and specified in the design stage of stator to ensure that a generator as whole meets the technical performance requirements. The
fabricated stator frame of hydroelectric generator is designed for electrical and mechanical applications. The stator frames are of larger diameters widely used in electrical machines and the arrangement of the same are different in shape and size. These frames are subjected to static as well as dynamic loads which may be uniform or non-uniform in nature depending upon its operating conditions. The study of complete stator is very much useful even to modify or optimize a small parameter.

Keywords
