Development status of Resolver and Harmonic Drive Gear is described in this paper. These items were selected as having high-priority in the field of Moving Mechanical Components (MMCS), to be developed using own technology, by the Technical Committee on Space Parts and Components. Institute of Space Technology & Aeronautics, JAXA has been responsible for the development. In FY2004, the Resolver design was fixed, based on evaluations including performance of the resolver-to-digital electric circuit, ball bearing frictional torque characteristics, manufacturing ability. The qualification test is scheduled in FY 2005. As for the Harmonic Drive Gear, the effect of grease amount and rotational speed on the life of the Harmonic Drive Gear was examined in air tests. However, an engineering model test in vacuum showed that the life was much shorter in vacuum than in air, and that 'lost-motion', which was useful to detect the life of the Gear operated in air, may not be used in vacuum. The qualification test is scheduled in FY 2005, and the test conditions will be set, based on the analysis of these experimental data.
