| Outline of Final Research Achievements |
In this study, to investigate applicability of high temperature superconducting (HTS) coils to armature winding of AC rotational machines, test devices to evaluate AC loss characteristics in HTS coils combined with iron core were developed and AC loss reduction in HTS coils was studied. Based on the electromagnetic field analysis using FEM, it was found that the perpendicular magnetic field can be reduced by properly arranging the magnetic material around the HTS coil winding. By using test devices for the 1-phase and 3-phase AC loss measurements, the AC loss reduction by arranging magnetic materials around the HTS coil winding was demonstrated.
