摘要

设计了一种基于迈斯纳效应的超导转子旋转驱动装置，利用驱动装置的定子线圈产生的磁场在空心转子内壁窗口产生的转动力矩驱动转子旋转。对超导转子旋转驱动力进行了有限元分析，结果表明，驱动力矩近似与驱动电流的平方成正比。在4.2 K温度、30 Pa气压下进行了转子旋转实验，30 A驱动电流下转子转速达到了8512 r/min。实验结果为进一步优化装置运行参数及提高转子旋转稳定性奠定了基础。

Abstract

A spin drive device of superconducting rotor was designed based on Meissner effect. The electromagnetic field generated by the stator coils engenders rotating torque on the superconducting rotor through the windows on its inner wall. The driving force was calculated using finite element analysis and the results show that the driving torque is approximately in proportional to the square of drive current. Rotation experiments were performed at 4.2 K

30 Pa. Rotation speed of 8512 r/min was achieved with 30 A drive current. The experimental results will be good references for the further improvement of operating parameters and rotation stability of superconducting rotor.
