Development of High Speed Alternator for Gas Turbine Engine

A high-speed alternator is deigned and experimentally evaluated for its performance with load. For testing the alternator a partial admission turbine drive is optimally designed and fabricated. The turbine drive system is analyzed for stresses and critical speed. The alternator, which consists of permanent magnet surrounded by a stator, was designed to get the required power. The alternator was tested at various speeds with load. This paper describes the salient features of the alternator and its performance characteristics.
