Abstract Integrating superconducting elements in an electric motor can greatly increase its power density. By doing so, lighter and more powerful machines can be produced for applications such as aviation, wind turbines and marine propulsion. Superconducting tapes can be stacked and magnetised to produce powerful trapped-flux magnets. The experimental setup was designed to allow measurements in a low temperature environment, providing tightness for the rotating part. We report on the design and construction of the setup and results from its first operation. The temperatures achieved during the experimental measurements reached 15 K, close to the actual operational temperatures of a liquid hydrogen cooled motor. The application of hydrogen onboard an aircraft is highly advantageous due to the possibility of its application as both coolant and fuel. Examination of the operation of the trapped-flux magnets at such temperatures is crucial for the understanding of the behavior of fully superconducting motors for future applications.

在接近 15 K 的温度下测试超导电机的实验系统

摘要 在电动机中集成超导元件可以大大提高其功率密度。通过这样做，可以为航空、风力涡轮机和船舶推进等应用生产更轻、更强大的机器。超导带可以堆叠和磁化以产生强大的捕获磁通磁铁。实验装置旨在允许在低温环境中进行测量，为旋转部件提供密封性。我们报告了该装置的设计和构造以及其首次运行的结果。实验测量期间达到的温度达到 15 K，接近液氢冷却电机的实际运行温度。由于氢可用作冷却剂和燃料，因此在飞机上使用氢是非常有利的。
