Outline of Final Research Achievements

This research evaluated the AC losses in high temperature superconducting (HTS) coil and tape under electromagnetic environment of HTS rotating machine. These results shows the AC loss characteristics in HTS coil inserted in an iron core, and the AC loss in HTS tape in the rotating magnetic field. AC loss with the iron core is increase than the without condition. Especially, the outside HTS tape of the HTS coil is extremely increase than the other tape. The AC losses in the rotating magnetic field are same level to the perpendicular magnetic field conditions.
