Abstract
Under an NREL subcontract the Electrical and Computer Engineering Department of the University of Colorado has designed a 20 kilowatt, twelve pole, permanent magnet, electric generator which can supply 150% of rated power over a speed range from 60 to 120 RPM. The generator was fabricated and assembled by the Denver electric motor manufacturer, Unique Mobility. The generator is being tested on the National Wind Technology Center (NWTC) dynamometer. This dynamometer provides generator speeds from 0 to 150 RPM. Static and steady-state electrical and mechanical generator parameters will be given as well as voltage and efficiency vs speed curves, and winding temperature rise. Preliminary dynamometer results for the complete variable speed electrical system including the AC-DC-AC power electronics will be presented. Also, these results will be examined for factors which must be considered if the prototype design is to be scaled up to a 300 kilowatt size.
