One of the greatest challenges in designing the superconducting field winding for a superconducting generator (SCG) is balancing mechanical loads while limiting heat that can enter via mechanical structure. This paper outlines the thermal and mechanical co-design of the field coils for a low speed, high torque, partially superconducting generator using LTS wire. Mechanical design is focused...
With the growing prevalence of electrical propulsion technology in aerospace and new energy applications, high-temperature superconducting (HTS) motors have garnered substantial interest due to their high efficiency and power density. Among these, axial flux motors (AFMs) stand out for their compact design and superior efficiency, positioning them as a promising candidate for future electrical...
High-purity aluminum armatures present a viable alternative to traditional superconducting armatures, which can face quench issues during AC operation despite their high-power density. Leveraging the low electrical resistance and lightweight properties of high-purity aluminum at cryogenic temperatures, this study presents the development of an armature for a 500 kW partially superconducting...
Axial-flux permanent magnet (AFPM) motors have gained significant attention in industries such as electric vehicles and ships due to their compact size, high torque density, and superior efficiency. While various AFPM designs have been proposed, this study focuses on the yokeless and concentrated armature structure, which offers unique advantages by eliminating the stator yoke. This reduces...
Using a superconducting bulk into the rotor enables torque generation by inducing current through an external armature, similar to the principle of an induction motor, without the need for direct current application to the rotor. This topology can reduce rotor resistance losses compared to conventional induction motors due to the low resistance of the superconducting material. Moreover, this...
Introduction
A torque tube with a low heat-conduction spoke torque tube was introduced in an earlier study. This study explores the characteristics and design trade-offs of this topology using a combination of analytical models and experimental validation. Results indicate that the spoke-supported topology generally favors small diameters due to its negligible heat leakage. Additionally,...
