電動執行機構的關鍵優勢便是高寬比的平穩和客戶可運用的穩定的推動力，較大電動執行機構造成的推動力可達到225000kgf，能做到這么大推動力的僅有液控閥電動執行機構，但液控(kong)閥(fa)電動執(zhi)行機構工(gong)程造價要比電動式高許多。

電動執行器(qi)的(de)(de)抗偏移工作(zuo)能力(li)是非常(chang)好的(de)(de)，輸(shu)出的(de)(de)推動力(li)或(huo)扭矩大部(bu)分是穩定(ding)的(de)(de)，能夠(gou)非常(chang)好的(de)(de)擺脫(tuo)物質(zhi)的(de)(de)不平衡(heng)感，做(zuo)到對加工工藝主要(yao)參數(shu)的(de)(de)精確操縱，因此線性(xing)度比(bi)氣(qi)(qi)動執行器(qi)要(yao)高。假如(ru)適用伺服(fu)放大器(qi)，能夠(gou)非常(chang)容易(yi)地完成正反面功效的(de)(de)交(jiao)換，還可以輕(qing)輕(qing)松(song)松(song)設(she)置斷(duan)信號閥位情況(維持/開全(quan)/關(guan)完)，而常(chang)見故障時，一(yi)定(ding)滯留在(zai)原點，它(ta)是氣(qi)(qi)動執行器(qi)所作(zuo)不上，氣(qi)(qi)動執行器(qi)務必憑借一(yi)套組(zu)成維護系統軟件來完成保位
