摘　　要：介绍了超导球转子的悬浮结构和原理。讨论了悬浮结构的电磁分布特点和悬浮力的计算。进行了超导球转子的悬浮实验,通过控制悬浮电流可将转子悬浮在旋转轴方向上的任意高度。结果为进一步提高转子悬浮的稳定性和刚度提供了参考。The suspension structure and method of superconducting sphere rotor were introduced. The properties of electromagnetic field distribution and the calculation of suspension force were discussed. From the experiment, it is found that the rotor can change the suspension height along the direction of spin axis by controlling the current of suspension coil. The results give some useful references which can enhance the suspension stability and the suspension stiffness of superconducting sphere rotor.
