The growing use of electrical energy in the world leads to new problem concerning the generation of electrical energy. The advent of turbo generators opened a new era in the state of the art of alternator design. High centrifugal forces developed due to higher speed will be a threat to the laminations of the rotor. In addition to that, the traditional rotor is not adaptable for large rating synchronous generators as it is difficult to build with acceptable mechanical stress, rigidity and critical speeds. In order to overcome these drawbacks a Solid Rotor Alternator (SRA) is evolved.
