| 摘 要： | 针对飞轮电池目前存在的主要问题，如价格和可靠性，提出了一种新型被动磁悬浮支承系统，系统由轴向永磁磁力轴承和径向电动磁力轴承两部分构成．从电动磁力轴承的悬浮机理出发，分析转子在特定磁场下运动时的电磁力，建立了转子的状态方程，继而导出稳定运转条件，并通过设计实例导出转子在一定的设计参数下可在任何转速下稳定运转的重要结论．

| Abstract: | A new type passive support system of magnetic suspension was presented to overcome the shortcomings of the flywheel battery. This system was made up of axial permanent magnetic mapnetic bearing and radial electrodynamic magnetic bearing. The operational principle of the electrodynamic magnetic bearing was introduced. The electromagnetic force exerted on the rotor in specific magnetic field was analyzed. Its state equations were built and stability condition was found. An important conclusion was drawn that the rotor can run stably at any speed as long as the design parameters are appropriate. |
