In this paper, a simple and stable energy-storage flywheel system with high temperature superconducting levitation is presented. This system has new methods in drive system and electromagnetic damper. In order to have stable levitation, a superconductor and a permanent magnet are used, and 3 permanent magnets support the top of the shaft. In the part of drive system, 8-poles permanent magnet and 8 coils are used to cancel electromagnetic force in the radial direction. A magnetic damper consisting of permanent magnet for levitation and 4 coils is presented, which lies at each end of the shaft. When the shaft vibrates in the direction perpendicular to the shaft, the current flows in the damper coil. It generates the electromagnetic force. The force is in proportion with vibration frequency of the shaft, so that the force behaves like damping forces. Using this system, we have stable levitation, and vibrations at resonance frequencies can be suppressed significantly.

提出了一种简单、稳定的高温超导悬浮储能飞轮系统。该系统在传动系统和电磁阻尼器上都有新的设计方法。为了具有稳定的悬浮，使用超导体和永磁体，3个永磁体支撑轴的顶部。驱动部分采用8极永磁体和8个线圈来抵消径向电磁力。提出了一种由悬浮永磁体和四个线圈组成的磁阻尼器，该磁阻尼器位于轴的两端。当轴在垂直于轴的方向上振动时，电流在阻尼线圈中流动。它产生电磁力。该力与轴的振动频率成比例，使得该力表现为阻尼力。使用该系统，我们可以实现稳定的悬浮，并且可以显著抑制共振频率下的振动。
