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.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果である、超伝導バルクの加工技術の検討によって、超伝導バルクを応用した回転機や軸受等の設計自由度を飛躍的に向上させることが可能と考えられる。また、これまでバルクの形状による制約で設計することが困難であった分野へも、その応用範囲が広がることとなり、電力機器応用の分野のみならず様々な分野への応用が期待できる。そして、それらの実用化によって社会全般に貢献すること考えられる。
