High-Speed Cryogenic Alternator Development. Volume 2.
Abstract
The engineering design basis was established to design a high-speed cryogenic turbine-driven electric generator, operating on gas-lubricated bearings at speeds up to 180,000 rpm with an output of 100 watts of electricity. A permanent magnet alternator was designed, manufactured, and tested at both room temperature and cryogenic temperatures. The alternator was tested with leading unity and lagging power factors. At cryogenic temperatures, in the order of 100K (-280F), tests were conducted and the turboalternator was evaluted at speeds up to 220,000 rpm, and with electrical power output values up to 109 watts. An alternator electromagnetic efficiency as high as 98 percent was measured. (Author)
