伺(si)服電(dian)(dian)(dian)機可(ke)使控(kong)制(zhi)速(su)(su)度,位置(zhi)精度非常(chang)準確,可(ke)以(yi)(yi)將(jiang)電(dian)(dian)(dian)壓信號(hao)轉(zhuan)(zhuan)化為轉(zhuan)(zhuan)矩和(he)轉(zhuan)(zhuan)速(su)(su)以(yi)(yi)驅動控(kong)制(zhi)對象(xiang)。伺(si)服電(dian)(dian)(dian)機轉(zhuan)(zhuan)子轉(zhuan)(zhuan)速(su)(su)受輸(shu)入信號(hao)控(kong)制(zhi),并能快速(su)(su)反應,在(zai)自(zi)動控(kong)制(zhi)系(xi)統中,用作執行(xing)元件(jian),且(qie)具有機電(dian)(dian)(dian)時間常(chang)數小、線(xian)性度高(gao)、始動電(dian)(dian)(dian)壓等(deng)特性,可(ke)把所收到的電(dian)(dian)(dian)信號(hao)轉(zhuan)(zhuan)換成電(dian)(dian)(dian)動機軸(zhou)上(shang)的角位移或(huo)角速(su)(su)度輸(shu)出。分為直流(liu)和(he)交(jiao)流(liu)伺(si)服電(dian)(dian)(dian)動機兩(liang)大類,其主要特點是(shi),當信號(hao)電(dian)(dian)(dian)壓為零(ling)時無自(zi)轉(zhuan)(zhuan)現象(xiang),轉(zhuan)(zhuan)速(su)(su)隨著轉(zhuan)(zhuan)矩的增加而勻(yun)速(su)(su)下降(jiang)。
伺(si)服電(dian)機(ji)(ji)是指在伺(si)服系(xi)統中控制(zhi)機(ji)(ji)械元件(jian)運轉(zhuan)的發動機(ji)(ji),是一種補助馬達間接變速(su)裝置(zhi)。伺(si)服電(dian)機(ji)(ji)可使控制(zhi)速(su)度(du),位置(zhi)精度(du)非(fei)常準確,可以(yi)將電(dian)壓信號(hao)(hao)轉(zhuan)化為(wei)轉(zhuan)矩和轉(zhuan)速(su)以(yi)驅(qu)動控制(zhi)對(dui)象。伺(si)服電(dian)動機(ji)(ji)又稱執行電(dian)動機(ji)(ji),在自動控制(zhi)系(xi)統中,用作執行元件(jian),把所收到的電(dian)信號(hao)(hao)轉(zhuan)
