<p> l及AL值大小，可參照Microl對(duì)照表。例如: 以T50-52材，線圈5圈半，其L值為T50-52(表示OD為0.5英吋)，經(jīng)查表其AL值約為33nH </p> <p> L=33，江西電子線圈創(chuàng)新服務(wù).(5.5)2=998，江西電子線圈創(chuàng)新服務(wù).25nH≒1μH </p> <p>

所述凸塊3a卡入凹槽內(nèi)。裝配時(shí)，將鐵芯3裝配在鐵殼1的底板上，由于凸塊3a和凹槽的定位作用，可防止鐵芯3發(fā)生轉(zhuǎn)動(dòng)，更便于電磁線圈總成的安裝。所述鐵芯3與鐵殼1的底板之間設(shè)置有絕緣片10；所述鐵芯3的頂面上均布有若干個(gè)收納孔4，工作時(shí)，電磁鐵的頂面與制動(dòng)鼓難免發(fā)生摩擦而產(chǎn)生碎屑，這些碎屑則被收納在收納孔4內(nèi)。所述線圈骨架11套在鐵芯3上；所述鐵芯3及電磁線圈總成外部的鐵殼1內(nèi)腔中注塑有pps填充物2。所述鐵芯3的中心設(shè)有裝配孔，所述鐵殼1的底板上設(shè)有中心孔；所述鐵芯3的裝配孔與鐵殼1的中心孔形狀、尺寸相對(duì)應(yīng)，且上下對(duì)齊形成注塑通孔；所述注塑通孔的前、后側(cè)面為弧形面，左、右側(cè)面為平面。在該注塑通孔內(nèi)注塑有與其形狀尺寸相匹配的尼龍芯7，所述尼龍芯7開設(shè)有軸向的插孔8，所述插孔8為矩形孔，呈45°傾斜，與制動(dòng)臂末端的折彎部位相匹配，安裝使用時(shí)，制動(dòng)臂末端的折彎部位插接在插孔8內(nèi)。所述尼龍芯7底端的周邊設(shè)置有向外延伸的凸緣7a，所述鐵殼1中心的中心孔底口周邊設(shè)有與凸緣7a相對(duì)應(yīng)的卡臺(tái)，所述凸緣7a與卡臺(tái)對(duì)應(yīng)卡緊。這種結(jié)構(gòu)設(shè)計(jì)，可防止尼龍芯7從注塑通孔內(nèi)脫出，從而降低故障率。以上*為本實(shí)用新型的實(shí)施方式。</p><div
