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...
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....
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...
Aviation electric propulsion is characterized by distributed propulsion, flexible maneuverability, and high efficiency with low pollution. The aviation superconducting electric propulsion system based on the concept of direct-drive power generation from turbines, which is one of the most promising solutions for meeting the power demands of high-power aviation electric propulsion aircraft. This...
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)...
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...
