除了铁粉材料本身特有的天然气隙分布结构外,加隙于E形铁粉磁芯,可再提高储能容量。但基于安培-圈温升的限制,E形磁芯的加隙处理仅在磁导率较高的材料-26,-40及-52有价值.
在Percent Effective Permeability vs. AC Flux Density Graph, Percent Permeability vs. DC Magnetizing Force Graph 和 Ampere Turns vs. DC Energy Storage for Optimum-Gapped E Cores Graph 显出了加隙对材料-26的基本磁性的典型影响。E形磁芯的磁化曲线跟环形磁芯的曲线有点不同。此不同处是由于不同的几何形状有不同的漏磁情况。同理,不同大小的E形磁芯之间也有一些差异,这些曲线图仅供参考而矣
材料-40和-52也出现类似的结果,材料-40的磁导率初值大约比材料-26和-52低20%,但当把这两种材料加隙处理後, 大家的有效磁导率便接近得多了。除了提高能量储存外,加隙处理还大大降低了这些材料在DC偏流时的摆动,其表现类似无隙的-8、-18、-30,和-34材料,由于材料-26,-40及-52比材料-8、-l8、-30,-34和-35便宜,此举便提供了另一个在设计上极吸引的选择。
在铁粉里加一个分立的空隙,对有效磁导率并无太大的影响,因此,相对于铁氧类和铁合金叠片类,E形铁粉磁芯的加隙处理是不重要的。
材料-26的E形介隙磁芯在最佳距离时的储能曲线图显示在Energy Storage Curves for optimum butt-gapped E Cores in -26 Material.底部。当线组结构相同时,用材料-52可达到类似或稍高的储能容量,用材料-40就可得稍低的能量容量。
介隙一词是指两个标准E形磁芯的实质分离(被间隔物介入)。例如一对磁芯,三对脚之间的距离均为0.01寸,其介隙便等于0.01寸,这就形成了相等于0.02寸的有效分立间隙:0.01寸的介隙即相等于一个0.02寸的中足间隙。
在E Core listing所示的E形磁芯系列里的E168、E168A、E220和E305型号,均有标准的中足间隙。E168、E168A型号可提供每只中足间隙为0.015寸的E形磁芯,一套两只合起来便成为中足间隙为0.030寸的磁芯;E220提供每只中足隙为0.020寸的磁芯。
