摘要： 针对飞轮系统在高转速时功耗大的问题,设计了基于超导磁悬浮轴承的微飞轮系统样机,研究了超导磁悬浮轴承对飞轮系统功耗的影响.微飞轮系统采用超导磁悬浮轴承作为支撑机构,以平面直流无刷电机作为驱动装置,在保证超导轴承场冷高度和电机间隙的条件下设计真空系统,通过搭建飞轮能耗实验平台,对超导磁悬浮飞轮系统的功耗进行分析,并通过测试不同场冷高度下的飞轮系统降速曲线,研究场冷高度对超导磁悬浮轴承的摩擦损耗影响.实验结果表明,在同样功耗下飞轮转子的最高转速可达到33 000 r/min,在15 000 r/min时超导磁悬浮轴承的功耗仅为机械飞轮系统功耗的1/7,并可以通过增加场冷高度进一步减少系统功耗.超导磁悬浮技术可以满足飞轮系统高转速、低功耗的要求．

Abstract: A prototype of the micro-flywheel system with the superconducting magnetic bearing has been designed concerning the problem of huge loss at a high rotating speed of flywheel systems. This micro-flywheel system adopted the superconducting magnetic bearing as the supporting mechanism, and the brushless planar DC motor as driving device. Vacuum system was designed within the restrictions of field-cooling height and motor gap, so that the flywheel could operate stably in the vacuum circumstance. The experimental platform of flywheel was build to analyze the energy consumption of the superconducting magnetic levitation flywheel system and study the influence of the power consumption of the flywheel system by the superconducting magnetic levitating bearing. The influence of friction loss of the superconducting magnetic bearing by the cooling height was studied through testing the spin-down curve of the flywheel. Test result shows that the maximum speed of the flywheel rotor could reach up to 33 000 r/min at the same energy consumption, and the energy consumption of superconducting magnetic bearing is only 1/7 of that of mechanic bearing at the 15 000 r/min rotating speed. The result also indicates that the loss of superconducting magnetic bearing reduces as the cold height increases, and superconducting magnetic technology can satisfy the need of low power consumption at high rotating speed．
