Investigations of high temperature generator designs and generator components such as insulations, magnetic materials, diodes, and bearings for operation in a 600 F high altitude ambient are described. Interlaminar insulation coatings for cobalt iron magnetic sheet steels were investigated and best choices are identified. A new coil insulation system in the form of a rugged monolithic structure was developed using a new ceramic tape and an encapsulation of a compound of commercial glass. Dry lubricated bearing technology developments were extended to more than double the life over previous similar bearings. High temperature SiC diode technology developments were extended to more than double the rating over prior SiC diodes. A conceptual design of a lighter weight, higher power density synchronous generator utilizing these new components is presented having a specific weight of 2.3 lbskVA. Author
