| Outline of Final Research Achievements |
High-temperature superconductivity is a advanced material that can handle electromagnetic energy more than that of normal-temperature magnetic materials. Thanks to the unique characteristic, the significant downsizing, high output, and high efficiency of industrial equipment that convert power and energy is feasible which accelerates the efficiency of the system.
Research and development of a superconducting armature coil that achieves strong magnetization inside a bulk superconductor rotating machine, which is a crystal mass of a superconducting material, was carried out. Conduct demonstration experiments from the design of a superconducting armature having both functions of magnetizing coil and armature coil in a rotating machine with a bulk body, demonstrate the principle by partial analysis of the rotating machine internal structure and electromagnetic analysis using the finite element method Research was conducted on rotating machines of 15 kW and 1 MW class.

| Academic Significance and Societal Importance of the Research Achievements |
学術的な意義として、過去の関連先行研究では見られたかった回転機機器内における着磁手法や回転機モデルを示すことで、超伝導材料の新たな応用技術の礎を確立できた。主流である回転機よりも安全かつ作業効率的に有利な機器内着磁法が実現できることを研究成果にて示している。また周囲の磁性材料や超伝導コイルの構造を改良することによる出力トルクへの影響も明らかにした。社会的意義として動力やエネルギーを変換する産業用回転機では大幅な小型化、高出力化、高効率化がその系（システム）の効率化を促す。船舶の推進動力だけでなく、大型EVや航空機動力、風力発電機と比較して空間や重量制限などにおいてもさらなる開発が期待できる。
