Identification of Mechanical Characteristics of Superconductor proceeding Bearing

초전도 저널베어링의 기계적 특성에 대한 연구

For designing high Tc superconductor proceeding bearing(HTSJB) which is used on a flywheel energy storage system which requests the free of the bearing loss caused by the friction, it is necessary to understand the basic characteristics of the classical superconductor proceeding bearing because the mechanical characteristics of the HTSJB are identified by the magnetic relationships between the permanent magnet(PM) and the high Tc superconductor(HTS). In this paper, using the method, frozen image model, the force problems between the PM and the HTS were solved and then the dynamic characteristics of the rotor inside of the HTSJB can be expected in advance by using the basic characteristics between the PM and the HTS. The coefficient of friction of the HTSJB was measured in the vacuum environment. From the results, the mechanical characteristics of HTSJB can be identified using the numerical models.
