我们提出了一个一般的无网格描述的磁场分布在各种电磁机器，致动器和设备。我们的方法是基于传递关系和傅立叶理论，它给出了一个广泛的一类二维（2-D）边值问题的磁场解。这种技术可以应用于旋转，线性和管状永磁致动器，无论是无槽或开槽电枢。除了永磁电机，这种技术可以应用于任何2-D几何形状的限制，几何形状应该包括矩形区域。该方法通过求解每个区域的拉普拉斯方程和泊松方程以及一组边界条件来获得电磁场分布。在这里，我们比较的方法与有限元分析的各种例子，并显示其适用于广泛的一类几何形状。
We present a general mesh-free description of the magnetic field distribution in various electromagnetic machines, actuators, and devices. Our method is based on transfer relations and Fourier theory, which gives the magnetic field solution for a wide class of two-dimensional (2-D) boundary value problems. This technique can be applied to rotary, linear, and tubular permanent-magnet actuators, either with a slotless or slotted armature. In addition to permanent-magnet machines, this technique can be applied to any 2-D geometry with the restriction that the geometry should consist of rectangular regions. The method obtains the electromagnetic field distribution by solving the Laplace and Poisson equations for every region, together with a set of boundary conditions. Here, we compare the method with finite-element analyses for various examples and show its applicability to a wide class of geometries.
