Abstract

Aviation electric propulsion requires reliable, high-current, low-loss armature windings with low mass to achieve high motor power density. A new approach using parallel-stacked superconducting tapes in wet windings has been proposed to meet these requirements. The coil was designed and tested in liquid nitrogen. This paper focuses on the AC loss characterization of the HTS coil by comparing experimental and simulation results. Instead of employing a coupled circuit model with uncertain resistivity values, directly using the experimentally measured current distribution provides a faster solution with good agreement to the experimental results. The method can be used to predict AC losses at higher currents.
