伺(si)服(fu)電(dian)(dian)機(ji)可(ke)使控制(zhi)速度(du),位置精度(du)非常(chang)準(zhun)確(que),可(ke)以(yi)將電(dian)(dian)壓信號(hao)轉(zhuan)化為(wei)(wei)轉(zhuan)矩和(he)轉(zhuan)速以(yi)驅動(dong)控制(zhi)對象(xiang)。伺(si)服(fu)電(dian)(dian)機(ji)轉(zhuan)子轉(zhuan)速受輸(shu)(shu)入信號(hao)控制(zhi),并能快速反應(ying),在自動(dong)控制(zhi)系(xi)統中(zhong),用(yong)作(zuo)執行元(yuan)件(jian),且具有(you)機(ji)電(dian)(dian)時(shi)間常(chang)數小、線性度(du)高、始(shi)動(dong)電(dian)(dian)壓等特性,可(ke)把所(suo)收(shou)到的電(dian)(dian)信號(hao)轉(zhuan)換成電(dian)(dian)動(dong)機(ji)軸上的角位移或角速度(du)輸(shu)(shu)出。分為(wei)(wei)直流和(he)交流伺(si)服(fu)電(dian)(dian)動(dong)機(ji)兩(liang)大類,其主要特點(dian)是,當信號(hao)電(dian)(dian)壓為(wei)(wei)零時(shi)無自轉(zhuan)現象(xiang),轉(zhuan)速隨著轉(zhuan)矩的增加而勻速下降。
伺服電機(ji)是指(zhi)在(zai)伺服系統(tong)中(zhong)控(kong)制機(ji)械元件(jian)運轉(zhuan)的發動機(ji),是一種補(bu)助(zhu)馬達(da)間接(jie)變(bian)速(su)裝置。伺服電機(ji)可使(shi)控(kong)制速(su)度,位(wei)置精(jing)度非常準確(que),可以(yi)將電壓信號轉(zhuan)化為轉(zhuan)矩和轉(zhuan)速(su)以(yi)驅(qu)動控(kong)制對象。伺服電動機(ji)又稱(cheng)執(zhi)行(xing)電動機(ji),在(zai)自動控(kong)制系統(tong)中(zhong),用作(zuo)執(zhi)行(xing)元件(jian),把所收到的電信號轉(zhuan)
