建立了Halbach轴向磁力联轴器的三维分析模型。磁场和转矩的确定，首先解决一个2-D领域的问题，在径向位置，径向磁通密度被假定为零。然后将2-D问题的解决方案纳入3-D磁荷片模型，以便能够准确计算完整的3-D场和扭矩。所提出的模型进行了比较与三维有限元分析模型。新的三维磁场和扭矩分析方法可以扩展到其他三维轴向磁装置的建模。
A 3-D analytical model is presented for a Halbach axial magnetic coupling. The field and torque are determined by first solving a 2-D field problem at the radial location in which the radial flux density is assumed zero. The solution to the 2-D problem is then incorporated into a 3-D magnetic charge sheet model so as to enable the complete 3-D fields and torque to be accurately computed. The presented model is compared with a 3-D finite element analysis model. The new 3-D field and torque analysis approach can be extended to model other 3-D axial magnetic devices.
