| Outline of Final Research Achievements |
This research is a basic research for the practical application of the integrated non-contact magnetic bearing using the superconducting bulk, and is for solving the problem of the effective optimal placement of the divided bulk including the processing technology.
As a result of this research, the integrated superconducting magnetic bearing (SMB) is constructed by actually using the design method considering the effective magnetic placement proposed in this research, and the effect of the optimal placement is verified. In this verification process, we were able to clear a number of considerations such as examination of bulk processing technology, performance evaluation of divided bulk, and construction of its design method. As a final result, we were able to confirm the effect brought about by the optimal placement, and were able to show the effectiveness of this research.
