伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)SV是伺(si)服(fu)(fu)(fu)系(xi)統(tong)的(de)(de)簡稱，例如：伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)SV-DA是英威騰品牌的(de)(de)伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)。伺(si)服(fu)(fu)(fu)系(xi)統(tong)是用來(lai)控制(zhi)機(ji)(ji)器(qi)人的(de)(de)控制(zhi)器(qi)，它能(neng)(neng)夠(gou)實現精確的(de)(de)速(su)度(du)和位置控制(zhi)，具有高(gao)精度(du)、高(gao)動(dong)(dong)態(tai)性(xing)能(neng)(neng)等優點1。伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)SV通常由(you)伺(si)服(fu)(fu)(fu)驅動(dong)(dong)器(qi)和伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)兩部(bu)分組(zu)成，其中伺(si)服(fu)(fu)(fu)驅動(dong)(dong)器(qi)負責(ze)接收來(lai)自控制(zhi)系(xi)統(tong)的(de)(de)指(zhi)令(ling)，并將其轉換為伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)所需的(de)(de)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流，而(er)伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)則根(gen)據這些指(zhi)令(ling)產生相(xiang)應的(de)(de)運動(dong)(dong)輸出。與普通電(dian)(dian)(dian)機(ji)(ji)相(xiang)比，伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)SV具有更高(gao)的(de)(de)控制(zhi)精度(du)和更快(kuai)的(de)(de)動(dong)(dong)態(tai)響應速(su)度(du)，能(neng)(neng)夠(gou)適應各(ge)種復雜的(de)(de)應用場景。系(xi)統(tong)由(you)何服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)、PLC、相(xiang)機(ji)(ji)等組(zu)成。上海SV-ML04伺(si)服(fu)(fu)(fu)電(dian)(dian)(dian)機(ji)(ji)安(an)裝

伺服電動機(ji)應(ying)具備以下基本要求：

寬廣的(de)調(diao)(diao)速范圍：伺服電機應能夠在速度范圍內進行(xing)平(ping)滑的(de)調(diao)(diao)節。無(wu)論是在低速還是高速，電機都應能夠穩定運行(xing)，并且能夠實(shi)現(xian)精(jing)確的(de)速度控制。

快(kuai)速(su)響應：伺服電機(ji)應具有快(kuai)速(su)的(de)(de)響應能力，能夠在短時間內達到(dao)所需的(de)(de)轉速(su)和扭矩。這對于(yu)需要(yao)快(kuai)速(su)動作的(de)(de)應用來說非(fei)常重要(yao)，例如在工業自動化生產線上的(de)(de)定位控制或者(zhe)機(ji)器(qi)人的(de)(de)運動控制。

精確(que)控(kong)制(zhi)(zhi)：伺服電機(ji)應能夠實現精確(que)的(de)(de)速度(du)和位置(zhi)(zhi)控(kong)制(zhi)(zhi)。電機(ji)的(de)(de)速度(du)和位置(zhi)(zhi)應與(yu)輸入(ru)的(de)(de)控(kong)制(zhi)(zhi)信號準(zhun)確(que)對應，從而實現高(gao)精度(du)的(de)(de)運(yun)動控(kong)制(zhi)(zhi)。

穩(wen)定性：伺服電機(ji)應能夠在各種工作條件下保持穩(wen)定的(de)運行狀態。無論(lun)是(shi)在負(fu)載變化(hua)(hua)、環境溫度(du)變化(hua)(hua)還(huan)是(shi)電源(yuan)波動的(de)情況下，電機(ji)都應能夠保持穩(wen)定的(de)轉速(su)和扭矩輸出。

耐用性(xing)和(he)可靠(kao)性(xing)：伺服電機應具有較高的(de)耐用性(xing)和(he)可靠(kao)性(xing)，能夠長時間(jian)地在高負載和(he)高頻率的(de)環(huan)境(jing)下工作，并且不(bu)需要(yao)頻繁的(de)維護和(he)更換部件。

易于安裝和(he)維(wei)護(hu)：伺服電機應(ying)具有簡單的安裝和(he)維(wei)護(hu)要求，方便用(yong)(yong)戶進(jin)行(xing)安裝和(he)使用(yong)(yong)，并且能夠在(zai)需要維(wei)護(hu)時方便地進(jin)行(xing)拆卸和(he)更(geng)換部件。

浙(zhe)江英威騰IMS20A伺(si)服(fu)(fu)電機(ji)(ji)功率伺(si)服(fu)(fu)電機(ji)(ji)的應(ying)用(yong)(yong)在電氣(qi)控制中運用(yong)(yong)很普遍。

伺服電(dian)機線纜(lan)選擇方法如下：

線纜材(cai)(cai)質。伺服(fu)電機線纜材(cai)(cai)質要(yao)求特別高(gao)，需要(yao)選擇具有耐高(gao)溫(wen)、抗老化、耐油、耐磨、抗干擾等特性的(de)材(cai)(cai)料(liao)(liao)。常用的(de)線纜材(cai)(cai)質有PUR、PVC、TPU、PE等，其中(zhong)PUR材(cai)(cai)料(liao)(liao)是所有材(cai)(cai)質中(zhong)性能棒、使用壽命長(chang)的(de)材(cai)(cai)料(liao)(liao)。

導(dao)線(xian)(xian)數(shu)量。伺服電機線(xian)(xian)纜的導(dao)線(xian)(xian)數(shu)量要與使(shi)用的伺服控制器匹配。一般(ban)情(qing)況(kuang)下，伺服電機線(xian)(xian)纜的導(dao)線(xian)(xian)數(shu)量是22根或24根（包括屏(ping)蔽層(ceng)和(he)非屏(ping)蔽層(ceng)導(dao)線(xian)(xian)）。

屏蔽等級(ji)。伺服(fu)(fu)電機線纜的(de)屏蔽等級(ji)應該根(gen)據伺服(fu)(fu)電機所(suo)處的(de)環境和噪聲等級(ji)來(lai)選擇。一般來(lai)說，屏蔽等級(ji)越高，線纜的(de)抗(kang)干(gan)擾能力就越強。

伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)（servo motor）是指(zhi)在伺服(fu)(fu)(fu)系統(tong)中(zhong)(zhong)控制機(ji)(ji)械元件(jian)運轉(zhuan)的(de)發(fa)動(dong)(dong)機(ji)(ji)，是一種補助馬(ma)達間(jian)接變速(su)(su)(su)(su)裝置(zhi)。伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)可使控制速(su)(su)(su)(su)度(du)(du)，位置(zhi)精度(du)(du)非常準確，可以將電(dian)(dian)(dian)(dian)(dian)壓信號轉(zhuan)化(hua)為轉(zhuan)矩和轉(zhuan)速(su)(su)(su)(su)以驅動(dong)(dong)控制對象。伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)轉(zhuan)子(zi)轉(zhuan)速(su)(su)(su)(su)受輸入信號控制，并能快速(su)(su)(su)(su)反應，在自動(dong)(dong)控制系統(tong)中(zhong)(zhong)，用(yong)作執行(xing)元件(jian)，且(qie)具(ju)有機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)時(shi)間(jian)常數小(xiao)、線性(xing)度(du)(du)高、始動(dong)(dong)電(dian)(dian)(dian)(dian)(dian)壓等特性(xing)，可把所收(shou)到的(de)電(dian)(dian)(dian)(dian)(dian)信號轉(zhuan)換成(cheng)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)軸上的(de)角(jiao)位移或角(jiao)速(su)(su)(su)(su)度(du)(du)輸出。分為直流(liu)和交流(liu)伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)兩大(da)類，其主要特點是，當信號電(dian)(dian)(dian)(dian)(dian)壓為零時(shi)無自轉(zhuan)現象，轉(zhuan)速(su)(su)(su)(su)隨著轉(zhuan)矩的(de)增(zeng)加(jia)而勻速(su)(su)(su)(su)下降。伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)在微電(dian)(dian)(dian)(dian)(dian)子(zi)生(sheng)(sheng)產加(jia)工，比如各類芯(xin)片(pian)的(de)生(sheng)(sheng)產，就少不了(le)伺服(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)帶動(dong)(dong)的(de)機(ji)(ji)械臂。

伺(si)(si)服電機(ji)(ji)并不(bu)(bu)是必須帶減速(su)(su)機(ji)(ji)。加不(bu)(bu)加減速(su)(su)機(ji)(ji)是由(you)客戶使用的(de)工況所決定(ding)的(de)。例如在重載(zai)、高(gao)(gao)精(jing)度、高(gao)(gao)響應、高(gao)(gao)穩定(ding)性等(deng)場合，有時需(xu)要使用減速(su)(su)機(ji)(ji)來匹配伺(si)(si)服電機(ji)(ji)的(de)性能(neng)，而在一(yi)些輕(qing)載(zai)、低(di)速(su)(su)、中精(jing)度等(deng)場合，有時會(hui)選擇不(bu)(bu)帶減速(su)(su)機(ji)(ji)的(de)伺(si)(si)服電機(ji)(ji)。
