Emcn considers the influence of the different flux distributions and leakage flux in alternator. the calculation accuracy is greater than conventional mec. emcn possess advantage of conventional mec and fem
等效磁網路法又考慮了電機內部的磁通分佈的不同和漏磁通的影響，因此其計算精度遠遠高於傳統的等效磁路法。 -
The emcn model is set up by use of flux - tube method. in this method, the segment in which the flux density is relatively even is considered to be an element, the permeance of each element can be calculated by use of conventional method. finally the permeance network can be set up by connecting each node with permeances, then the parameters and performance can be obtained
其基本思想是通過磁通管原理，把電機內部磁通密度相對均勻的部分看作一個單元，計算出單元的磁導，最後再把各個節點用等效磁導連接起來構成一個磁導的網路圖，再根據電路的基本解法求得各個節點的磁位，從而求得電機的參數和性能。 -
The equivalent magnet circuit network ( emcn ) method is based on combination between conventional mec and fem. the conventional magnet circuit method transfer the field in electrical machine into magnet circuit to analyze and calculate the parameters and performance of electrical machine. the emcn splits the magnet circuit into many elements according to the different flux distribution in the machine
等效磁網路法的思想是來源於有限元法和等效磁路法的結合，傳統的等效磁路法是把磁場轉化為磁路計算，而有限元法是把電機內部根據磁場分佈的不同，把求解區域劃分成各個單元，因此，等效磁網路法是結合兩者的優點而提出來的。 -
There are few elements in emcn, the mesh time can be reduced greatly and calculation time is more less than fem time
因此，此方法的剖分單元很少，節省了許多剖分時間，故計算時間比有限元法縮短了很多。 -
Emcn can transfer the area in machine into several elements, each node and mesh are fixed and irrelevant to rotor rotation. only the values of permeances are related to motor rotation, but all the relations of the permeances are fixed
等效磁網路法是把電機內部化分成許多單元，各個節點和單元的劃分是固定的，與電機的轉動無關，與電機轉子位置相關的量是各個部分的磁導值，而各個部分的相對關系不變。
