Space agencies and companies are aiming at high-resolution deep space observation. To perform high-resolution observation, disturbance suppression methods are important. Resolution of observed data degrades by not only external disturbances but also internal disturbances, which are generated by the equipment on space telescopes. Especially, vibrations and heat predominantly cause degradation of the quality of observed data. In this paper, a contactless micro-vibration isolator using the flux pinning effect is presented to solve the vibration and heat transfer problems for future space observation missions. Our proposed micro-vibration isolator utilizes the flux pinning force and eddy current damping to suppress micro-vibration passively. In addition, the proposed system allows restriction of the thermal propagation path as disturbance sources and mission equipment are not connected mechanically but electromagnetically. To evaluate the frequency response of the proposed system, a vibration experiment and numerical calculations are performed. The experimental results in this paper indicate that the proposed system can suppress micro-vibration passively using the flux pinning force and eddy current damping. Moreover, validation of frequency response design using numerical calculation has been shown by comparing the numerical calculation results with the vibration experiment results.
