伺服電機(jī)：

伺服電機(jī)（servo motor ）是指在伺服系統(tǒng)中控制機(jī)械元件運(yùn)轉(zhuǎn)的發(fā)動(dòng)機(jī)，是一種補(bǔ)助馬達(dá)間接變速裝置。

伺服電機(jī)可以控制速度，位置精度非常準(zhǔn)確，可以將電壓信號(hào)轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動(dòng)控制對象。伺服電機(jī)轉(zhuǎn)子轉(zhuǎn)速受輸入信號(hào)控制，并能快速反應(yīng)，在自動(dòng)控制系統(tǒng)中，用作執(zhí)行元件，且具有機(jī)電時(shí)間常數(shù)小、線性度高等特性，可把所收到的電信號(hào)轉(zhuǎn)換成電動(dòng)機(jī)軸上的角位移或角速度輸出。分為直流和交流伺服電動(dòng)機(jī)兩大類，其主要特點(diǎn)是，當(dāng)信號(hào)電壓為零時(shí)無自轉(zhuǎn)現(xiàn)象，轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降。

伺服電機(jī)工作原理：

1、伺服系統(tǒng)（servo mechanism）是使物體的位置、方位、狀態(tài)等輸出被控量能夠跟隨輸入目標(biāo)（或給定值）的任意變化的自動(dòng)控制系統(tǒng)。伺服主要靠脈沖來定位，基本上可以這樣理解，伺服電機(jī)接收到1個(gè)脈沖，就會(huì)旋轉(zhuǎn)1個(gè)脈沖對應(yīng)的角度，從而實(shí)現(xiàn)位移，因?yàn)椋�伺服電機(jī)本身具備發(fā)出脈沖的功能，所以伺服電機(jī)每旋轉(zhuǎn)一個(gè)角度，都會(huì)發(fā)出對應(yīng)數(shù)量的脈沖，這樣，和伺服電機(jī)接受的脈沖形成了呼應(yīng)，或者叫閉環(huán)，如此一來，系統(tǒng)就會(huì)知道發(fā)了多少脈沖給伺服電機(jī)，同時(shí)又收了多少脈沖回來，這樣，就能夠很大的控制電機(jī)的轉(zhuǎn)動(dòng)，從而實(shí)現(xiàn)定位，可以達(dá)到0.001mm。直流伺服電機(jī)分為有刷和無刷電機(jī)。有刷電機(jī)成本低，結(jié)構(gòu)簡單，啟動(dòng)轉(zhuǎn)矩大，調(diào)速范圍寬，控制容易，需要維護(hù)，但維護(hù)不方便（換碳刷），產(chǎn)生電磁干擾，對環(huán)境有要求。因此它可以用于對成本敏感的普通工業(yè)和民用場合。

無刷電機(jī)體積小，重量輕，出力大，響應(yīng)快，速度高，慣量小，轉(zhuǎn)動(dòng)平滑，力矩穩(wěn)定。控制復(fù)雜，容易實(shí)現(xiàn)智能化，其電子換相方式靈活，可以方波換相或正弦波換相。電機(jī)免維護(hù)，效率很高，運(yùn)行溫度低，電磁輻射很小，長壽命，可用于各種環(huán)境。

2、交流伺服電機(jī)也是無刷電機(jī)，分為同步和異步電機(jī)，運(yùn)動(dòng)控制中一般都用同步電機(jī)，它的功率范圍大，可以做到很大的功率。大慣量，***高轉(zhuǎn)動(dòng)速度低，且隨著功率增大而快速降低。因而適合做低速平穩(wěn)運(yùn)行的應(yīng)用。

3、伺服電機(jī)內(nèi)部的轉(zhuǎn)子是永磁鐵，驅(qū)動(dòng)器控制的U/V/W三相電形成電磁場，轉(zhuǎn)子在此磁場的作用下轉(zhuǎn)動(dòng)，同時(shí)電機(jī)自帶的編碼器反饋信號(hào)給驅(qū)動(dòng)器，驅(qū)動(dòng)器根據(jù)反饋值與目標(biāo)值進(jìn)行比較，調(diào)整轉(zhuǎn)子轉(zhuǎn)動(dòng)的角度。伺服電機(jī)的精度決定于編碼器的精度（線數(shù)）。

交流伺服電機(jī)和無刷直流伺服電機(jī)在功能上的區(qū)別：交流伺服要好一些，因?yàn)槭钦�弦波控制，轉(zhuǎn)矩脈動(dòng)小。直流伺服是梯形波。但直流伺服比較簡單，便宜。
