| 摘 要： | 针对在磁力轴承中各磁极之间的磁路存在磁耦合，影响转子的控制精度，给控制系统的设计带来一定的困难，以及完全消除磁耦合比较困难的问题，利用低频磁场在空气介质中随距离的二次幂衰减的特性，在结构上把各磁极之间的磁路断开，以削弱磁路之间的耦合。研究了两种弱耦合的径向磁力轴承在不同工况下的耦合特性，探讨了耦合机理和结构参数对耦合特性的影响，提出了弱耦合径向磁力轴承的耦合模型以及影响耦合特性的关键结构参数的选择准则。

| Abstract: | Magnetic coupling exists in magnetic bearing.It affects the controlling accuracy of the magnetic bearing.Magnetic coupling also brings some complicacy to the designing of the magnetic bearing control system.It is difficult to completely eliminate the magnetic coupling of a magnetic bearing because of its working principle and structural characteristic.The characteristic of that low frequency magnetic field attenuates quadratically with distance increasing was utilized to weaken magnetic coupling by means of... |
