Both electrostatic micro motor-generator and two types of electromagnetic micro motor-generators for a ultra micro gas turbine were studied experimentally. For the electrostatic micro motor-generator, the prototype of micro air turbines was designed and fabricated based on MEMS technology. This device ran stably up to 6000rev/min. At higher rotational speed, severe interaction between rotor and stator caused the test to be stopped. The mechanical loss by viscous drag in the rotor-stator gap was estimated analytically by examining realization of the electrostatic micro motor-generator. For the electromagnetic micro motor-generators, two different coil prototypes of Φ8.8×18.5mm size were designed and made based on conventional technique. The electrical loss caused by iron-loss of the generators were estimated. The electric output of 2.0W and 2.5W were obtained for a motor-generators operation at 50000rev/min.
