    Poster

    Growing environmental concerns have increased the demand for high-power-density electric propulsion systems. One way to achieve higher power density is through the use of superconducting technology. In particular, no-insulation (NI) high-temperature superconducting (HTS) coils offer improved power density due to their ability to carry high currents and withstand external...

    Poster

    The torque tube is crucial for the normal operation of high-temperature superconducting motors, serving as a mechanical support and torque transmission element. Including adiabatic performance, cold shrinkage performance and mechanical stress, the performances of torque tube are important indicators in superconducting electrical design, which need to be analyzed and studied comprehensively....

  3. 524. Fri-Af-Po.09-03: Magnetic field coil power supply using a flywheel generator with a planetary gear and a very small capacity inverter
    Dr Shuhei Kato (Nihon University)
    04/07/2025, 14:00
    Poster

    Flywheel generators are used as power sources for various plasma experiments because of their long-life span and high-power repetition. However, huge capacity inverters for energy conversion have been necessary to charge and discharge rotating energy. Furthermore, in conventional flywheel generators, the power output also decreases as the rotation speed decreases. In response to this, the...

  5. 213. Fri-Af-Po.09-05: Conceptual Design of an Axial Field Machine with Stacked Superconductors
    Haigening Wei (University of Cambridge)
    04/07/2025, 14:00
    Poster

    The development of high-temperature superconducting (HTS) electrical machines results in applications of various fields, as they have higher efficiency and power density. Axial field machine (AFM) is a machine topology with higher efficiency and power density, and is a novel way to achieve fully-superconducting electrical machine for various applications. Stacked HTS coated-conductors (CC)...

  6. 148. Fri-Af-Po.09-06: Shielding for trapped field stacks against cross field demagnetisation in a superconducting machine
    Qi Wang (University of Cambridge)
    04/07/2025, 14:00
    Poster

    High-Temperature Superconducting (HTS) Coated Conductors (CCs) can be sliced and stacked together and utilised as Trapped Field Stacks (TFSs) for electric motors and generators after magnetisation. However, TFSs are vulnerable to higher-order harmonic waves within the air gap of electric machines, which stem from the stator's alternating arrangement of slots and teeth, leading to a phenomenon...
