摘要
为了降低飞轮储能系统的磁轴承损耗,设计了一种永磁偏置磁轴承,分析了该永磁偏置磁轴承的工作原理,并建立了数学模型。在此基础上,对永磁偏置磁轴承进行了参数设计和仿真验证。通过飞轮储能系统试验,验证了该永磁偏置磁轴承设计的合理性。与纯电磁轴承相比,永磁偏置磁轴承显著降低了磁轴承功耗,为飞轮储能系统的长期稳定运行提供了基础。
In order to reduce the loss of magnetic bearing in flywheel energy storage system,a permanent magnet biased magnetic bearing is designed.The working principle of the permanent magnet biased magnetic bearing is analyzed and the mathematical model is established.On this basis,the parameters of the permanent magnet biased magnetic bearing are designed,and the electromagnetic field is analyzed with the finite element simulation software.The design of the permanent magnet biased magnetic bearing is verified by the experiment of the flywheel energy storage system.Compared with the magnetic bearing,the loss of magnetic bearing is significantly reduced,which provides the basis for the long-term stable operation of flywheel energy storage system.
