1.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(duì)應(yīng)的角度，從而實(shí)現(xiàn)位移，因?yàn)?，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(duì)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，就能夠很精確的控制電機(jī)的轉(zhuǎn)動(dòng)，從而實(shí)現(xiàn)精確的定位，可以達(dá)到0.001mm。

               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)，目前運(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，zui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(chǎng)，轉(zhuǎn)子在此磁場(chǎng)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)）。交流伺服系統(tǒng)已成為當(dāng)代高性能伺服系統(tǒng)的主要發(fā)展方向，使原來的直流伺服面臨被淘汰的危機(jī)。
