Abstract
We examine the expected performance of a brushless motor/generator that uses trapped-flux (TF) bulk high-temperature superconductors (HTSs) to provide magnetomotive force, where the stator windings are used to create the TF. A key feature is the use of dysprosium (Dy) for the stator and rotor cores. We also examine methods to energize TF in HTS for generators used in pulsed-power applications.
► Use of Dy for core material increases t in situ magnetization of trapped-flux HTS. ► Hysteresis loss in Dy needs to be reduced. ► Bootstrap in situ magnetization can be done with two pulsed-power generators.
