偏置线圈式电磁轴承的研究

Study on AMB with a Bias Coil

介绍了双线图结构的电磁轴承工作原理，推导了这种电磁轴承的数学模型，给出了控制系统框图。通过实验，与普通不带偏置线圈的电磁轴承进行了比较，得到了性能不变，功耗显著降低的结论。

This paper discusses the working principle of a kind of Active Magnetic Bearing (AMB) With a bias coil,derives the AMB’s mathematic model and gives the frame of control system.The experiment proves that thix AMB’spower wasting is much lower than the common AMB without bias coil.
