Micromachine gas turbine generator with centrifugal impeller of diameter 10mm is under development at Tohoku University, in conjunction with Ishikawajima-Harima Heavy Industries Co., Ltd., Tohoku-Gakuin University, and Sankyo Seiki Mfg. Co., Ltd. This paper is focus on a development of micro motor-generator with 100W output at 870,000 rev/min. An ultra high speed micro motor-generator is designed and a 400,000 rev/min operation prototype model is made. Basic characteristics are measured and the design performance is confirmed. The micro motor-generator can run up to 170,000 rev/min with 120° rectangular wave drive circuit.
