製動器的構造及其工作原理

    製動器的構造及其工作原理

    製動器的工作原理：當電梯處於靜止狀態時，曳引電動機、電磁製動器的線圈中均無電流通過
，這時因電磁鐵芯間沒有吸引力、製動瓦塊在製動彈簧壓力作用下，將製動輪抱緊，保證電機不旋轉；dangyeyindiandongjitongdianxuanzhuandeshunjian，zhidongdiancitiezhongdexianquantongshitongshangdianliu，diancitiexinxunsucihuaxihe，daidongzhidongbishiqizhidongdanhuangshouzuoyongli，zhidongwakuaizhangkai，yuzhidonglunwanquantuoli
