磁悬浮框架飞轮磁轴承技术研究与发展现状

The current research and future development of the magnetically suspended gimballing flywheel (MSGFW) and high-precision magnetic bearing are expounded. According to the rotor levitation force, MSGFW can be classified as the magnetic resistance force configuration, Lorentz force configuration and hybrid force configuration. Based on the three types of the flywheel configurations above, the development process of MSGFW is discussed. On the basis, the spherical magnetic resistance magnetic bearing and Lorentz magnetic bearing are introduced in detail. Their operating principles are analyzed through using the magnetic circuit maps. The advantages and disadvantages of the magnetic bearings of the same type are compared. Finally, the developing prospect of MSGFW and high-precision magnetic bearing are expected. It points out that the high dynamic response translation spherical magnetic bearing with collocation between detection and control, the standard magnetically suspended momentum sphere and the magnetically suspended control & sensitive sphere will be the primary research directions of MSGFW.
