Superconducting coils are designed for carrying high electrical current at low losses for use in future superconducting power transmission lines, transformers, fault current limiters, and electric machines for aircraft. The coils in the armature (typically the stator winding) of electric machines are exposed to highly dynamic magnetic excitation. In this environment, it is critical to...
This study presents a comprehensive analysis of magnetization in ReBCO-coated conductor tape and helical wound tape conductors using both numerical and finite element method (FEM) approaches. Magnetization is a crucial factor limiting the practical application of superconducting cables and coils, and accurate prediction and minimization of magnetization are vital for the development of...
In this work, semi-analytical models to compute alternating current (AC) power loss in stacks of high-temperature superconductor YBa2Cu3O7-x (or Y-Ba-Cu-O) tapes subjected to a time-varying magnetic field perpendicular to the tapes with zero transport current are developed. Both standard and non-standard arrangements of tapes are considered. The models take into account screening of the...
