YEJ電(dian)(dian)機(ji)全(quan)稱(cheng)是：YEJ系列(lie)(lie)電(dian)(dian)磁三相(xiang)異步(bu)制(zhi)動(dong)電(dian)(dian)機(ji)（簡稱(cheng)：YEJ系列(lie)(lie)電(dian)(dian)磁制(zhi)動(dong)電(dian)(dian)動(dong)機(ji)），是全(quan)封閉、自(zi)扇冷、鼠(shu)籠(long)型附加直(zhi)流電(dian)(dian)磁鐵(tie)制(zhi)動(dong)器的(de)三相(xiang)異步(bu)電(dian)(dian)動(dong)機(ji)，是在Y系列(lie)(lie)電(dian)(dian)動(dong)機(ji)的(de)后端蓋(gai)與風扇之間附加一個(ge)
直(zhi)流盤式電磁(ci)制動(dong)器(qi)組成(cheng),是Y系(xi)列的派生系(xi)列。
應用范圍
適用于各(ge)類要(yao)求(qiu)快速制動(dong)、準確定位、往復運(yun)轉(zhuan)、頻繁起動(dong)、制動(dong)的各(ge)種機(ji)械，作為主傳(chuan)(chuan)動(dong)和(he)輔助(zhu)傳(chuan)(chuan)
之用(yong)的機(ji)(ji)械(xie)(xie)(xie)(xie)設備。例如：電(dian)動閥門、橡膠(jiao)化(hua)工(gong)機(ji)(ji)械(xie)(xie)(xie)(xie)、金屬加(jia)工(gong)機(ji)(ji)床、包裝機(ji)(ji)械(xie)(xie)(xie)(xie)、木工(gong)機(ji)(ji)械(xie)(xie)(xie)(xie)、食品機(ji)(ji)械(xie)(xie)(xie)(xie)、化(hua)工(gong)機(ji)(ji)械(xie)(xie)(xie)(xie)、紡(fang)織機(ji)(ji)械(xie)(xie)(xie)(xie)、建筑機(ji)(ji)械(xie)(xie)(xie)(xie)以(yi)及齒輪減(jian)速機(ji)(ji)等。
特點
制動(dong)(dong)可靠、制動(dong)(dong)力矩可調、轉(zhuan)子(zi)無軸向(xiang)竄(cuan)動(dong)(dong)、使用方便。
標準(zhun)型式(shi)
電動機(ji)符(fu)合(he)JB/T6428--92的要求(qiu)。
電動機額定(ding)電壓為(wei)(wei)380V，額定(ding)頻率為(wei)(wei)50HZ，外殼防護(hu)等級為(wei)(wei)IP44，制(zhi)動器為(wei)(wei)IP23，冷卻方法為(wei)(wei)IC411，基(ji)準工作制(zhi)為(wei)(wei)連續工作制(zhi)SI，絕緣(yuan)等級為(wei)(wei)B級。
原理與結構
YEJ型(xing)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的(de)(de)直流圓盤(pan)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)安裝在(zai)電(dian)(dian)機(ji)非(fei)軸伸端(duan)的(de)(de)端(duan)蓋上，當制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)接入(ru)電(dian)(dian)源，制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)也同時(shi)工(gong)作，由于電(dian)(dian)磁吸(xi)力(li)作用電(dian)(dian)磁鐵吸(xi)引銜鐵并壓縮彈(dan)簧，制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)盤(pan)與銜鐵、端(duan)蓋脫(tuo)開，電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)開始連轉。當切斷(duan)電(dian)(dian)源時(shi)，制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)電(dian)(dian)磁鐵失去電(dian)(dian)磁吸(xi)力(li)、彈(dan)簧推動(dong)(dong)(dong)(dong)銜鐵壓緊(jin)制(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)盤(pan)，在(zai)磨擦力(li)矩的(de)(de)作用下，電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)立即(ji)停止轉動(dong)(dong)(dong)(dong)。
安裝型式(shi)
B3：機座帶(dai)底腳，端蓋無凸(tu)絕。
