AC Loss of Stacked HTS Tapes Subjected to a Rotating Magnetic Field

The study of AC losses in high-temperature superconducting (HTS) tapes is of great importance. Most previous studies on the electromagnetic properties of HTS have focused exclusively on the AC losses generated by one-dimensional alternating magnetic field and the transmitted current but not on the properties of superconducting tapes in the presence of rotating magnetic fields such as motors. This work, based on finite element simulations under the T-A formulation, explores the AC loss of the central tape in stacked tapes under various conditions, and shows the variation situation of AC losses.
