Research Institution
An innovative solution for improvement in power density, efficiency, and reliability of the electric starter generator (ES/ G) is proposed using induction technology. Single set stator-rotor assembly per power section and lack of rotating windings and rectifiers will substantially improve power density and reliability. The induction generator is turned off within a fraction of a second under fault conditions.It provides regulated voltage output. Ways for improving efficiency and thermal management are proposed including sealed cooling system instead of spray cooling, high thermal conductivity filled epoxy insulation, improved processing of electrical steel for the stator and rotor cores. The result is a compact generator design that will exceed the power density and efficiency targeted for this application. Phase I activity includes conceptual electromagnetic and thermal design and detailed analysis to verify performance, followed by Option period for further electromagnetic analysis using Finite Element techniques, and a detailed insulation scheme investigation, as well as complete layout of the of the dual output starter generator. The results of Phase I and Option will ensure development of demonstrable compact and efficient electric starter generator hardware in Phase II.
