Abstract

In response to increasing environmental regulations and the push towards electrification, superconducting motors have gained significant interest due to their high power density potential. This paper presents the design and analysis of a conceptual fully superconducting brushless motor featuring MgB

$_{2}$

armature windings and YBCO bulk superconductors in the rotor. The proposed motor utilizes post-assembly magnetization using field cooling, achieving a trapped magnetic field exceeding 2 T. Through optimization and magnetization analysis, the YBCO bulk-type designed motor calculated a 61% improvement in power density compared to a permanent magnet-type designed motor. The design also shows thermal losses of 1.58 kW, which can be effectively covered using LH

$_{2}$

cooling. These results present the feasibility of a high-performance, brushless design with HTS bulk field magnets, paving the way for relatively compact cryogenic motor applications.
