Abstract

We present the results of a two-dimensional electromagnetic finite-element analysis of a 1-kW-class high-temperature superconducting (HTS) wound-field synchronous motor that considers armature-current information, i.e., current phase angle β and current I_a, for maximum torque per ampere and flux-weakening control. The torque performance was analyzed using the d- and q-axis inductances, which were estimated when β and I_a were varied. Then, the characteristics of the magnetic field distribution and operating current margin of the HTS field coils were investigated based on various β and I_a values. Finally, suitable β and I_a were estimated as references for a future study.
