According to an electricity deregulation, distributed power generations such as microturbines are being considered as playing an important role. We are now developing a prototype 167kW, 51000min^<-1> generator for a 150kW microturbine system. The electrical generator applied in the microturbine system has a single shaft connecting a permanent magnet rotor, a centrifugal compressor and a radial turbine. The rotor is supported by two water lubricated bearings at each end of the permanent magnet rotor. In this paper, the results of electrical and thermal characteristics of the generator in a microturbine system are described. As a result of about 90% load heat run test, electrical efficiencies of the generator, which are calculated by calorimetric test, are 93.8% (including mechanical loss) and 96.9% (excluding mechanical loss).
