電動執行器的工作原理相對簡單。它由電機、減(jian)速(su)器(qi)和(he)執(zhi)行(xing)機(ji)構(gou)三(san)個(ge)主(zhu)要(yao)部(bu)分(fen)構(gou)成(cheng)。電(dian)機(ji)負(fu)責(ze)提(ti)供(gong)電(dian)能(neng)，減(jian)速(su)器(qi)則(ze)將(jiang)電(dian)機(ji)的(de)高(gao)速(su)旋(xuan)轉(zhuan)轉(zhuan)化(hua)為(wei)低(di)速(su)高(gao)扭(niu)矩(ju)的(de)旋(xuan)轉(zhuan)運(yun)動(dong)，執(zhi)行(xing)機(ji)構(gou)則(ze)將(jiang)這(zhe)些(xie)旋(xuan)轉(zhuan)運(yun)動(dong)進(jin)一(yi)步(bu)轉(zhuan)化(hua)為(wei)直(zhi)線(xian)運(yun)動(dong)或(huo)者(zhe)角(jiao)度(du)運(yun)動(dong)，從(cong)而(er)實(shi)現(xian)對(dui)負(fu)載(zai)的(de)精(jing)確(que)控(kong)製(zhi)。常(chang)見(jian)的(de)電(dian)動(dong)執(zhi)行(xing)器(qi)類(lei)型(xing)包(bao)括(kuo)直(zhi)線(xian)電(dian)動(dong)執(zhi)行(xing)器(qi)和(he)角(jiao)度(du)電(dian)動(dong)執(zhi)行(xing)器(qi)，它(ta)們(men)各(ge)自(zi)有(you)著(zhe)不(bu)同(tong)的(de)應(ying)用(yong)領(ling)域(yu)。

在選擇電動執行器時，需要考慮多個因素，包括負載要求、運動速度、環境條件以及控製精度等。負載要求決定了電動執行器的尺寸和功率，而運動速度則影響到執行器的響應時間。環境條件如溫度、濕shi度du以yi及ji是shi否fou有you腐fu蝕shi性xing物wu質zhi等deng，也ye會hui對dui電dian動dong執zhi行xing器qi的de選xuan擇ze產chan生sheng影ying響xiang。此ci外wai，控kong製zhi精jing度du直zhi接jie關guan係xi到dao執zhi行xing器qi的de性xing能neng，要yao求qiu高gao精jing度du控kong製zhi的de場chang景jing需xu要yao選xuan擇ze高gao精jing度du的de電dian動dong執zhi行xing器qi。
