一、半自(zi)動(dong)電(dian)動(dong)起(qi)子

在(zai)達到設(she)(she)定扭力后不會自(zi)動(dong)(dong)剎車(che)停止的起(qi)子，稱之為半自(zi)動(dong)(dong)電動(dong)(dong)起(qi)子。通常半自(zi)動(dong)(dong)設(she)(she)計為手按式。半自(zi)動(dong)(dong)有分AC高壓(ya)直插(cha)式，與經(jing)過電源變壓(ya)為DC低(di)壓(ya)式。

二、全自動電動起(qi)子(zi)

在達(da)到設定扭(niu)力后能夠完全自(zi)動(dong)(dong)剎車并停止(zhi)運轉的電(dian)動(dong)(dong)起(qi)子(zi)稱為全自(zi)動(dong)(dong)電(dian)動(dong)(dong)起(qi)子(zi)。全自(zi)動(dong)(dong)電(dian)動(dong)(dong)起(qi)子(zi)又分(fen)為AC高(gao)壓和DC低(di)壓兩個系列(lie)，根據操作啟動(dong)(dong)模式的不(bu)同(tong)又分(fen)為手按(an)式和下壓式兩種。

高壓(ya)(ya)系(xi)(xi)列電(dian)動(dong)(dong)起(qi)子不需(xu)要單(dan)獨電(dian)源供應器轉換(huan)電(dian)壓(ya)(ya)，直(zhi)接與市電(dian)連接，操作(zuo)快捷(jie)占用空間(jian)小(xiao)。低壓(ya)(ya)系(xi)(xi)列電(dian)動(dong)(dong)起(qi)子體積小(xiao)重量輕，由直(zhi)流馬達(da)驅(qu)動(dong)(dong)，壽命長(chang)安全系(xi)(xi)數(shu)高。手按式電(dian)動(dong)(dong)起(qi)子操作(zuo)啟(qi)(qi)動(dong)(dong)時只需(xu)用手指按住啟(qi)(qi)動(dong)(dong)杠(gang)桿，或壓(ya)(ya)板按鈕等。下壓(ya)(ya)式電(dian)動(dong)(dong)起(qi)子操作(zuo)啟(qi)(qi)動(dong)(dong)時無需(xu)用手指按住啟(qi)(qi)動(dong)(dong)杠(gang)桿，或壓(ya)(ya)板按鈕等，直(zhi)接對(dui)準工件壓(ya)(ya)下就可啟(qi)(qi)動(dong)(dong)。
