The reduction of CO2 emissions in maritime and port sectors has become an urgent issue, driving the need for electrification and highly efficient rotating machines. In this study, we investigate rim-drive rotating machines incorporating high-temperature superconducting (HTS) technology as a pathway toward carbon-neutral ports.A kW-class HTS rim-drive prototype was designed using sREBCO-coated conductors, and detailed finite element method (FEM) analyses were conducted to evaluate its electromagnetic characteristics under port-relevant operating conditions. Comparative simulations examined the impact of different magnetic circuit structures and field-pole configurations.These comparisons indicate that superconducting configurations can provide higher output density and efficiency, while also introducing challenges. These findings clarify performance trade-offs across magnetic circuit structures and highlight the potential of compact, high-efficiency HTS rim-drive machines for next-generation port applications.This presentation will focus on the design methodology, comparative evaluations, and practical implications for deploying superconducting rim-drive rotating machines in carbon-neutral port infrastructure.
