Abstract

The active magnetic bearings (AMBs) can greatly improve the stability of the flywheel system and increase the maximum flywheel speed. However, if the active magnetic bearing-flywheel system (AMB-FS) is placed in a rotating frame, the strong gyroscopic effect of high-speed flywheel will greatly affect the system stability. In this study, to realize the high stability of the AMB-FS at ultra-high flywheel speed with low power consumption, the cross feedback PID control was applied in the AMB-FS. The system stability and the performance of AMBs were studied. In the experiment, the gyroscopic effect of the flywheel was effectively suppressed. In the vacuum environment, the flywheel could runs stably at any speed within the range of 0 to 30000 rpm, and the power consumption of AMBs was only 17.82 W and the system had no need of cooling measures. The flywheel speed could exceed 31200 rpm and still possessed the speeding potential. The rotating frame test showed that the maximum frame rotational speed could reach 3.5 deg/s at the rated flywheel speed of 30000 rpm, and the AMBFS run stably.
