摘要
简要介绍了电磁力的基本理论,以径向电磁轴承为例,分别采用理论公式和磁场数值计算两种方法,给出对应于不同气隙和控制电流工况下电磁力的计算过程和结果,得出了较精确的磁轴承电磁力计算方法。
The basic theory of the eletromagnetic force is briefly introduced. Taking example of radical electromagnetic beating, a theoretic method and a magnetic field numerical simulation （FEM）are utilized to calculate electromagnetic force in the condition of different gaps and control currents. A relative accruate method is put forward to calculate electromagnetic force of the electromagnetic beating.
