詳細介紹:
東莞天機傳動(臺灣天機牌)微型電磁制動器亦是使用DC24V,其扭矩0.5Nm-5Nm稱之為微型扭矩。安裝法蘭可方形或者圓形但是4個安裝孔的尺寸不變(根據型號的大小變化)。微型(xing)電磁制動器定子通過法蘭安裝的型號,可以簡單地安裝到劈面/安裝板上。 微型電(dian)磁制動(dong)器由內置線圈的定子、填入填充材料的定子及電樞單元構成,定子通過安裝法蘭切實地固定到機械的支架等緊固的靜止部位。電樞單元由電、彈簧片及電樞輪轂組成,與旋轉子機對,并保持一定的間隙(0.2mm),正確進行組合,固定到被制動的軸(旋轉體)上。
該型微型電磁制動器(TJ-C-B)基本設計與微型電磁離合器(TJ-C-A)基本相同,是一種高性并且結構緊湊的微型制動器,其制動能強,最適合高精度定位,可以安裝在小型精密機械品上任何安裝位置,簡單且方便。微型電磁制動器具有安裝快捷、噪音低、制動平穩、耐用等優點,可與微電機配套使用,被廣泛應用于廣泛應用于門機驅動、電動輪椅、倉儲自動控制、自動門、醫療器械、步進電機等自動化機械傳動系統中,起快速停車、安全制動作用。
微型(xing)電磁制動器重要特征(zheng)就是在電路通(tong)斷(duan)瞬間,尤其是斷(duan)開(kai)瞬間會(hui)產生強大的感應(ying)電動勢。這(zhe)種電動勢通(tong)常是正常工作(zuo)電壓的幾倍至(zhi)幾百倍。如此高的沖擊電壓對電磁(ci)制動器本身損(sun)害(hai)極大,對后續設備也有很大影響。
