認(rèn)準(zhǔn)“上海韋米機(jī)電設(shè)備有限公司”，8年老店，產(chǎn)品實(shí)拍，保證產(chǎn)品原廠原裝，價(jià)格優(yōu)惠，售后無憂，歡迎新老客戶咨詢采購(gòu)！
德國(guó)博世力士樂（BOSCH-REXROTH）公司生產(chǎn)鐵氧體永磁的SD系列（17個(gè)規(guī)格）和稀土永磁的SE系列（8個(gè)規(guī)格）交流伺服電動(dòng)機(jī)和Servodyn SM系列的驅(qū)動(dòng)控制器。Indramat分部的MAC系列交流伺服電動(dòng)機(jī)共有7個(gè)機(jī)座號(hào)92個(gè)規(guī)格。
交流伺服電動(dòng)機(jī)定子的構(gòu)造基本上與電容分相式單相異步電動(dòng)機(jī)相似.其定子上裝有兩個(gè)位置互差90°的繞組，一個(gè)是勵(lì)磁繞組Rf，它始終接在交流電壓Uf上；另一個(gè)是控制繞組L，聯(lián)接控制信號(hào)電壓Uc。所以交流伺服電動(dòng)機(jī)又稱兩個(gè)伺服電動(dòng)機(jī)。
交流伺服電動(dòng)機(jī)的轉(zhuǎn)子通常做成鼠籠式，但為了使伺服電動(dòng)機(jī)具有較寬的調(diào)速范圍、線性的機(jī)械特性，無“自轉(zhuǎn)”現(xiàn)象和快速響應(yīng)的性能，它與普通電動(dòng)機(jī)相比，應(yīng)具有轉(zhuǎn)子電阻大和轉(zhuǎn)動(dòng)慣量小這兩個(gè)特點(diǎn)。目前應(yīng)用較多的轉(zhuǎn)子結(jié)構(gòu)有兩種形式：一種是采用高電阻率的導(dǎo)電材料做成的高電阻率導(dǎo)條的鼠籠轉(zhuǎn)子，為了減小轉(zhuǎn)子的轉(zhuǎn)動(dòng)慣量，轉(zhuǎn)子做得細(xì)長(zhǎng)；另一種是采用鋁合金制成的空心杯形轉(zhuǎn)子，杯壁很薄，僅0.2-0.3mm，為了減小磁路的磁阻，要在空心杯形轉(zhuǎn)子內(nèi)放置固定的內(nèi)定子.空心杯形轉(zhuǎn)子的轉(zhuǎn)動(dòng)慣量很小，反應(yīng)迅速，而且運(yùn)轉(zhuǎn)平穩(wěn)，因此被廣泛采用。
交流伺服電動(dòng)機(jī)在沒有控制電壓時(shí)，定子內(nèi)只有勵(lì)磁繞組產(chǎn)生的脈動(dòng)磁場(chǎng)，轉(zhuǎn)子靜止不動(dòng)。當(dāng)有控制電壓時(shí)，定子內(nèi)便產(chǎn)生一個(gè)旋轉(zhuǎn)磁場(chǎng)，轉(zhuǎn)子沿旋轉(zhuǎn)磁場(chǎng)的方向旋轉(zhuǎn)，在負(fù)載恒定的情況下，電動(dòng)機(jī)的轉(zhuǎn)速隨控制電壓的大小而變化，當(dāng)控制電壓的相位相反時(shí)，伺服電動(dòng)機(jī)將反轉(zhuǎn)。
永磁交流伺服電動(dòng)機(jī)同直流伺服電動(dòng)機(jī)比較，主要優(yōu)點(diǎn)有：
⑴無電刷和換向器，因此工作可靠，對(duì)維護(hù)和保養(yǎng)要求低。
⑵定子繞組散熱比較方便。
⑶慣量小，易于提高系統(tǒng)的快速性。
⑷適應(yīng)于高速大力矩工作狀態(tài)。
⑸同功率下有較小的體積和重量。
步進(jìn)電機(jī)作為一種開環(huán)控制的系統(tǒng)，和現(xiàn)代數(shù)字控制技術(shù)有著本質(zhì)的聯(lián)系。在目前國(guó)內(nèi)的數(shù)字控制系統(tǒng)中，步進(jìn)電機(jī)的應(yīng)用十分廣泛。隨著全數(shù)字式交流伺服系統(tǒng)的出現(xiàn)，交流伺服電機(jī)也越來越多地應(yīng)用于數(shù)字控制系統(tǒng)中。為了適應(yīng)數(shù)字控制的發(fā)展趨勢(shì)，運(yùn)動(dòng)控制系統(tǒng)中大多采用步進(jìn)電機(jī)或全數(shù)字式交流伺服電機(jī)作為執(zhí)行電動(dòng)機(jī)。雖然兩者在控制方式上相似（脈沖串和方向信號(hào)），但在使用性能和應(yīng)用場(chǎng)合上存在著較大的差異。現(xiàn)就二者的使用性能作一比較。
直流伺服電機(jī)可應(yīng)用在是火花機(jī)、機(jī)械手、精確的機(jī)器等。可同時(shí)配置2500P/R高分析度的標(biāo)準(zhǔn)編碼器及測(cè)速器，更能加配減速箱、令機(jī)械設(shè)備帶來可靠的準(zhǔn)確性及高扭力。 調(diào)速性好，單位重量和體積下，輸出功率高，大于交流電機(jī)，更遠(yuǎn)遠(yuǎn)超過步進(jìn)電機(jī)。多級(jí)結(jié)構(gòu)的力矩波動(dòng)小。
伺服電機(jī)工作原理
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)椋欧姍C(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。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(jiǎn)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)方便(換碳刷)，產(chǎn)生電磁干擾，對(duì)環(huán)境有要求。因此它可以用于對(duì)成本敏感的普通工業(yè)和民用場(chǎng)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)兔維護(hù)，效率很高，運(yùn)行溫度低，電磁輻射很小，長(zhǎng)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)，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，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UNNN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))。

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(zhǎng)壽命，可用于各種環(huán)境。

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UNNN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))。
伺服電動(dòng)機(jī)又稱執(zhí)行電動(dòng)機(jī)，在自動(dòng)控制系統(tǒng)中，用作執(zhí)行元件，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
交流伺服要好一些，因?yàn)槭钦也ǹ刂疲D(zhuǎn)矩脈動(dòng)小。直流伺服是梯形波。但直流伺服比較簡(jiǎn)單，便宜。

永磁交流伺服電動(dòng)機(jī)
自從德國(guó)MANNESMANN的Rexroth公司的Indramat分部在1978年漢諾威貿(mào)易博覽會(huì)上正式推出MAC永磁交流伺服電動(dòng)機(jī)和驅(qū)動(dòng)系統(tǒng)，這標(biāo)志著此種新一代交流伺服技術(shù)已進(jìn)入實(shí)用化階段。到20世紀(jì)80年代中后期，各公司都已有完整的系列產(chǎn)品。整個(gè)伺服裝置市場(chǎng)都轉(zhuǎn)向了交流系統(tǒng)。早期的模擬系統(tǒng)在諸如零漂、抗干擾、可靠性、精度和柔性等方面存在不足，尚不能完全滿足運(yùn)動(dòng)控制的要求，近年來隨著微處理器、新型數(shù)字信號(hào)處理器(DSP)的應(yīng)用，出現(xiàn)了數(shù)字控制系統(tǒng)，控制部分可完全由軟件進(jìn)行，稱為永磁交流伺服系統(tǒng)。
伺服電機(jī)原理
一、交流伺服電動(dòng)機(jī)
交流同服電動(dòng)機(jī)定子的構(gòu)造基本上與電容分相式單相異步電動(dòng)機(jī)相似，其定子上裝有兩個(gè)位置互差90°的繞組，一個(gè)是勵(lì)磁繞組Rf,它始終接在交流電壓Uf上;另一個(gè)是控制繞組L,聯(lián)接控制信號(hào)電壓Uc。所以交流伺服電動(dòng)機(jī)又稱兩個(gè)伺服電動(dòng)機(jī)。
交流伺服電動(dòng)機(jī)的轉(zhuǎn)子通常做成鼠籠式，但為了使伺服電動(dòng)機(jī)具有較寬的調(diào)速范圍、線性的機(jī)械特性，無“自轉(zhuǎn)”現(xiàn)象和快速響應(yīng)的性能,它與普通電動(dòng)機(jī)相比，應(yīng)具有轉(zhuǎn)子電阻大和轉(zhuǎn)動(dòng)慣量小這兩個(gè)特點(diǎn)。目前應(yīng)用較多的轉(zhuǎn)子結(jié)構(gòu)有兩種形式:一種是采用高電阻率的導(dǎo)電材料做成的高電阻率導(dǎo)條的鼠籠轉(zhuǎn)子，為了減小轉(zhuǎn)子的轉(zhuǎn)動(dòng)慣量，轉(zhuǎn)子做得細(xì)長(zhǎng);另一種是采用鋁合金制成的空心杯形轉(zhuǎn)子，杯壁很薄，僅0.2-0.3mm，為了減小磁路的磁阻，要在空心杯形轉(zhuǎn)子內(nèi)放置固定的內(nèi)定子.空心杯形轉(zhuǎn)子的轉(zhuǎn)動(dòng)慣量很小，反應(yīng)迅速，而且運(yùn)轉(zhuǎn)平穩(wěn)，因此被廣泛采用。
交流伺服電動(dòng)機(jī)在沒有控制電壓時(shí)，定子內(nèi)只有勵(lì)磁繞組產(chǎn)生的脈動(dòng)磁場(chǎng),轉(zhuǎn)子靜止不動(dòng)。當(dāng)有控制電壓時(shí)，定子內(nèi)便產(chǎn)生-一個(gè)旋轉(zhuǎn)磁場(chǎng),轉(zhuǎn)子沿旋轉(zhuǎn)磁場(chǎng)的方向旋轉(zhuǎn)，在負(fù)載恒定的情況下，電動(dòng)機(jī)的轉(zhuǎn)速隨控制電壓的大小而變化，當(dāng)控制電壓的相位相反時(shí)，伺服電動(dòng)機(jī)將反轉(zhuǎn)。
交流伺服電動(dòng)機(jī)的工作原理與分相式單相異步電動(dòng)機(jī)雖然相似，但前者的轉(zhuǎn)子電阻比后者大得多，所以伺服電動(dòng)機(jī)與單機(jī)異步電動(dòng)機(jī)相比，有三個(gè)顯著特點(diǎn):
1、起動(dòng)轉(zhuǎn)矩大
2、運(yùn)行范圍較廣
3、無自轉(zhuǎn)現(xiàn)象
正常運(yùn)轉(zhuǎn)的伺服電動(dòng)機(jī)，只要失去控制電壓，電機(jī)立即停止運(yùn)轉(zhuǎn)。當(dāng)伺服電動(dòng)機(jī)失去控制電壓后，它處于單相運(yùn)行狀態(tài)，由于轉(zhuǎn)子電阻大，定子中兩個(gè)相反方向旋轉(zhuǎn)的旋轉(zhuǎn)磁場(chǎng)與轉(zhuǎn)子作用所產(chǎn)生的兩個(gè)轉(zhuǎn)矩特性(T1-S1、T2- S2曲線)以及合成轉(zhuǎn)矩特性(T- S曲線)交流伺服電動(dòng)機(jī)的輸出功率一般是0.1-100W。當(dāng)電源頻率為50Hz，電壓有36V、110V、 220、380V; 當(dāng)電源頻率為400Hz，電壓有20V、26V、36V、115V等多種。
交流伺服電動(dòng)機(jī)運(yùn)行平穩(wěn)、噪音小。但控制特性是非線性，并且由于轉(zhuǎn)子電阻大，損耗大，效率低，因此與同容量直流伺服電動(dòng)機(jī)相比,體積大、重量重，所以只適用于0.5-100W的小功率控制系統(tǒng)。
伺服電機(jī)、測(cè)速電機(jī)、步進(jìn)電機(jī)。，
各種控制電機(jī)有各自的控制任務(wù):
如:伺服電動(dòng)機(jī)將電壓信號(hào)轉(zhuǎn)換為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動(dòng)控制對(duì)象;測(cè)速發(fā)電機(jī)將轉(zhuǎn)速轉(zhuǎn)換為電壓，并傳遞到輸入端作為反饋信號(hào)。步進(jìn)電動(dòng)機(jī)將脈沖信號(hào)轉(zhuǎn)換為角位移或線位移。
對(duì)控制電機(jī)的主要要求:動(dòng)作靈敏、準(zhǔn)確、重量輕、體積小、耗電少、運(yùn)行可靠等。
伺服電動(dòng)機(jī)又稱執(zhí)行電動(dòng)機(jī)。其功能是將輸入的電壓控制信號(hào)轉(zhuǎn)換為軸上輸出的角位移和角速度，驅(qū)動(dòng)控制對(duì)象。
伺服電動(dòng)機(jī)可控性好，反應(yīng)迅速。是自動(dòng)控制系統(tǒng)和計(jì)算機(jī)外圍設(shè)備中常用的執(zhí)行元件。伺服電動(dòng)機(jī)可分為兩類:直流伺服電動(dòng)機(jī)、交流伺服電動(dòng)機(jī)。
交流伺服電動(dòng)機(jī)就是一臺(tái)兩相交流異步電機(jī)。它的定子上裝有空間互差90°的兩個(gè)繞組:勵(lì)磁繞組和控制繞組。
交流伺服電動(dòng)機(jī)的工作原理與單相異步電動(dòng)機(jī)有相似之處。
勵(lì)磁繞組固定接在電源上，當(dāng)控制電壓為零時(shí)，電機(jī)無起動(dòng)轉(zhuǎn)矩，轉(zhuǎn)子不轉(zhuǎn)。
若有控制電壓加在控制繞組上，且勵(lì)磁電流i,和控制繞組電流I,不同相時(shí)，因此便產(chǎn)生兩相旋轉(zhuǎn)磁場(chǎng)。在旋轉(zhuǎn)磁場(chǎng)的作用下，轉(zhuǎn)子便轉(zhuǎn)動(dòng)起來。
交流伺服電動(dòng)機(jī)的特點(diǎn):不僅要求它在靜止?fàn)顟B(tài)下，能服從控制信號(hào)的命令而轉(zhuǎn)動(dòng)，而且要求在電動(dòng)機(jī)運(yùn)行時(shí)如果控制電壓變?yōu)榱悖妱?dòng)機(jī)立即停轉(zhuǎn)。
但如果交流伺服電動(dòng)機(jī)的參數(shù)選擇和一-般單相異步電動(dòng)機(jī)相似，電動(dòng)機(jī)經(jīng)轉(zhuǎn)動(dòng)，即使控制等于零，
電動(dòng)機(jī)仍繼續(xù)轉(zhuǎn)動(dòng)，電動(dòng)機(jī)失去控制，這種現(xiàn)象稱為“自轉(zhuǎn)”。
直流伺服電動(dòng)機(jī)的結(jié)構(gòu)與直流電動(dòng)機(jī)基本相同。只是為減小轉(zhuǎn)動(dòng)慣量，電機(jī)做得細(xì)長(zhǎng)一些。
直流伺服電動(dòng)機(jī)的工作原理也與直流電動(dòng)機(jī)相同。
供電方式:他勵(lì)供電。勵(lì)磁繞組和電樞分別由兩個(gè)獨(dú)立的電源供電。
測(cè)速發(fā)電機(jī)是一種轉(zhuǎn)速測(cè)量傳感器。在許多自動(dòng)控制系統(tǒng)中，它被用來測(cè)量旋轉(zhuǎn)裝置的轉(zhuǎn)速，向控制電路提供與轉(zhuǎn)速大小成正比的信號(hào)電壓。
測(cè)速發(fā)電機(jī)分為交流和直流兩種類型。
交流測(cè)速發(fā)電機(jī)
交流測(cè)速發(fā)電機(jī)又分為同步式和異步式兩種，這里只分析異步式交流測(cè)速發(fā)電機(jī)的工作原理。
異步式交流測(cè)速發(fā)電機(jī)的結(jié)構(gòu)與杯形轉(zhuǎn)子交流伺服電機(jī)相似，它的定子上有兩個(gè)繞組，一個(gè)是勵(lì)磁繞組，一個(gè)是輸出繞組。
直流測(cè)速發(fā)電機(jī)分永磁式和他勵(lì)式兩種。兩種電機(jī)的電樞相同，工作時(shí)電樞接負(fù)載電阻。但永磁式的定子使用磁鐵產(chǎn)生磁場(chǎng)，因而沒有勵(lì)磁線圈;他勵(lì)式的結(jié)構(gòu)與直流伺服電機(jī)相同，工作時(shí)勵(lì)磁繞組加直流電壓勵(lì)磁。
測(cè)速發(fā)電機(jī)的作用是將機(jī)械速度轉(zhuǎn)變?yōu)殡妷?信號(hào)，在自動(dòng)控制系統(tǒng)和計(jì)算裝置中作為檢測(cè)元件、校正元件等。如在恒速控制系統(tǒng)中，測(cè)速發(fā)電機(jī)將速度轉(zhuǎn)換為電壓信號(hào)作為反饋信號(hào)，達(dá)到調(diào)節(jié)速度的作用。
步進(jìn)電機(jī)是利用電磁鐵的作用原理，將脈沖信號(hào)轉(zhuǎn)換為線位移或角位移的電機(jī)。每來一個(gè)電脈沖，步進(jìn)電機(jī)轉(zhuǎn)動(dòng)一定角度，帶動(dòng)機(jī)械移動(dòng)一小段距離。
特點(diǎn):
(1)來一個(gè)脈沖，轉(zhuǎn)一個(gè)步距角。
(2)控制脈沖頻率，可控制電機(jī)轉(zhuǎn)速。
(3)改變脈沖順序，可改變轉(zhuǎn)動(dòng)方向。
由于步進(jìn)電動(dòng)機(jī)的這一工作職能正好符合數(shù)字控制系統(tǒng)要求，因此它在數(shù)控機(jī)床、鐘表工業(yè)及自動(dòng)記錄儀等方面都有很廣泛的應(yīng)用
種類:勵(lì)磁式和反應(yīng)式兩種。
區(qū)別在于勵(lì)磁式步進(jìn)電機(jī)的轉(zhuǎn)子上有勵(lì)磁線圈，依靠電磁轉(zhuǎn)矩工作。反應(yīng)式步進(jìn)電機(jī)的轉(zhuǎn)子上沒有勵(lì)磁線圈。依靠變化的的磁阻生成磁阻轉(zhuǎn)矩工作。反應(yīng)式步進(jìn)電機(jī)的應(yīng)用*廣泛，它有兩相、三相、多相之分。這里主要討論三相反應(yīng)式步進(jìn)電動(dòng)機(jī)的結(jié)構(gòu)和工作原理。
從結(jié)構(gòu)上看，自動(dòng)控制系統(tǒng)分為開環(huán)控制和閉環(huán)控制兩類。
開環(huán)控制系統(tǒng)結(jié)構(gòu)簡(jiǎn)單，控制對(duì)象按照控制指令工作，但不能根據(jù)輸出結(jié)果自動(dòng)調(diào)節(jié)，僅用于對(duì)控制精度要求不高的場(chǎng)合。
閉環(huán)控制系統(tǒng)結(jié)構(gòu)比較復(fù)雜。把輸出信號(hào)的一部分通過反饋環(huán)節(jié)引回到輸入端，與給定信號(hào)比較，得到誤差信號(hào)，再送入控制對(duì)象去調(diào)節(jié)輸出結(jié)果。如此反復(fù)循環(huán)，直至誤差為零。這種控制是通過反饋來實(shí)現(xiàn)的，所以也叫做反饋控制系統(tǒng)。
閉環(huán)控制系統(tǒng)(反饋控制系統(tǒng))的各個(gè)基本環(huán)節(jié)如下所示:
系統(tǒng)中各部分的作用如下:
給定元件-把控制指令變成給定值。它與被調(diào)量存在著一定的函數(shù)關(guān)系。 改變給定值，即可改變被調(diào)量。
檢測(cè)元件-把被調(diào)量檢測(cè)出來，按一定的函數(shù)關(guān)系反饋到輸入端。
比較元件-把反饋信號(hào)Ur與給定信號(hào)Ug,比較以獲取誤差信號(hào)Ud.
放大元件-當(dāng)誤差信號(hào)太微弱時(shí)，需要用放大元件把誤差信號(hào)放大到足以推動(dòng)執(zhí)行元件的程度。
執(zhí)行元件-直接推動(dòng)控制對(duì)象改變被調(diào)量。控制對(duì)象由 執(zhí)行元件推動(dòng)的各種裝置，如各種機(jī)械負(fù)載、發(fā)電機(jī)、加熱爐、閘門等，相應(yīng)的被調(diào)量就是轉(zhuǎn)速、電壓、溫度、位移等。
伺服電機(jī)和其他電機(jī)（如步進(jìn)電機(jī)）相比到底有什么優(yōu)點(diǎn)：
1、精度：實(shí)現(xiàn)了位置，速度和力矩的閉環(huán)控制；克服了步進(jìn)電機(jī)失步的問題；
2、轉(zhuǎn)速：高速性能好，一般額定轉(zhuǎn)速能達(dá)到2000～3000轉(zhuǎn)；
3、適應(yīng)性：抗過載能力強(qiáng)，能承受三倍于額定轉(zhuǎn)矩的負(fù)載，對(duì)有瞬間負(fù)載波動(dòng)和要求快速起動(dòng)的場(chǎng)合特別適用；
4、穩(wěn)定：低速運(yùn)行平穩(wěn)，低速運(yùn)行時(shí)不會(huì)產(chǎn)生類似于步進(jìn)電機(jī)的步進(jìn)運(yùn)行現(xiàn)象。適用于有高速響應(yīng)要求的場(chǎng)合；
5、及時(shí)性：電機(jī)加減速的動(dòng)態(tài)相應(yīng)時(shí)間短，一般在幾十毫秒之內(nèi)；
6、舒適性：發(fā)熱和噪音明顯降低。
簡(jiǎn)單點(diǎn)說就是：平常看到的那種普通的電機(jī)，斷電后它還會(huì)因?yàn)樽陨淼膽T性再轉(zhuǎn)一會(huì)兒，然后停下。而伺服電機(jī)和步進(jìn)電機(jī)是說停就停，說走就走，反應(yīng)極快。但步進(jìn)電機(jī)存在失步現(xiàn)象。
伺服電機(jī)的應(yīng)用領(lǐng)域就太多了。只要是要有動(dòng)力源的，而且對(duì)精度有要求的一般都可能涉及到伺服電機(jī)。如機(jī)床、印刷設(shè)備、包裝設(shè)備、紡織設(shè)備、激光加工設(shè)備、機(jī)器人、自動(dòng)化生產(chǎn)線等對(duì)工藝精度、加工效率和工作可靠性等要求相對(duì)較高的設(shè)備。
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)）
交流伺服電動(dòng)機(jī)的結(jié)構(gòu)主要可分為兩部分，即定子部分和轉(zhuǎn)子部分。其中定子的結(jié)構(gòu)與旋轉(zhuǎn)變壓器的定子基本相同，在定子鐵心中也安放著空間互成90度電角度的兩相繞組。其中一組為激磁繞組，另一組為控制繞組，交流伺服電動(dòng)機(jī)一種兩相的交流電動(dòng)機(jī)。 交流伺服電動(dòng)機(jī)使用時(shí)，激磁繞組兩端施加恒定的激磁電壓Uf，控制繞組兩端施加控制電壓Uk。當(dāng)定子繞組加上電壓后，伺服電動(dòng)機(jī)很快就會(huì)轉(zhuǎn)動(dòng)起來。 通入勵(lì)磁繞組及控制繞組的電流在電機(jī)內(nèi)產(chǎn)生一個(gè)旋轉(zhuǎn)磁場(chǎng)，旋轉(zhuǎn)磁場(chǎng)的轉(zhuǎn)向決定了電機(jī)的轉(zhuǎn)向，當(dāng)任意一個(gè)繞組上所加的電壓反相時(shí)，旋轉(zhuǎn)磁場(chǎng)的方向就發(fā)生改變，電機(jī)的方向也發(fā)生改變。 為了在電機(jī)內(nèi)形成一個(gè)圓形旋轉(zhuǎn)磁場(chǎng)，要求激磁電壓Uf和控制電壓UK之間應(yīng)有90度的相位差，常用的方法有：
1）利用三相電源的相電壓和線電壓構(gòu)成90度的移相
2）利用三相電源的任意線電壓
3）采用移相網(wǎng)絡(luò)
4）在激磁相中串聯(lián)電容器
異步型交流伺服電動(dòng)機(jī)指的是交流感應(yīng)電動(dòng)機(jī)。它有三相和單相之分，也有鼠籠式和線繞式，通常多用鼠籠式三相感應(yīng)電動(dòng)機(jī)。其結(jié)構(gòu)簡(jiǎn)單，與同容量的直流電動(dòng)機(jī)相比，質(zhì)量輕1/2，價(jià)格僅為直流電動(dòng)機(jī)的1/3。缺點(diǎn)是不能經(jīng)濟(jì)地實(shí)現(xiàn)范圍很廣的平滑調(diào)速，必須從電網(wǎng)吸收滯后的勵(lì)磁電流。因而令電網(wǎng)功率因數(shù)變壞。
同步型交流伺服電動(dòng)機(jī)雖較感應(yīng)電動(dòng)機(jī)復(fù)雜，但比直流電動(dòng)機(jī)簡(jiǎn)單。它的定子與感應(yīng)電動(dòng)機(jī)一樣，都在定子上裝有對(duì)稱三相繞組。而轉(zhuǎn)子卻不同，按不同的轉(zhuǎn)子結(jié)構(gòu)又分電磁式及非電磁式兩大類。非電磁式又分為磁滯式、永磁式和反應(yīng)式多種。其中磁滯式和反應(yīng)式同步電動(dòng)機(jī)存在效率低、功率因數(shù)較差、制造容量不大等缺點(diǎn)。數(shù)控機(jī)床中多用永磁式同步電動(dòng)機(jī)。與電磁式相比，永磁式優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單、運(yùn)行可靠、效率較高；缺點(diǎn)是體積大、啟動(dòng)特性欠佳。但永磁式同步電動(dòng)機(jī)采用高剩磁感應(yīng)，高矯頑力的稀土類磁鐵后，可比直流電動(dòng)外形尺寸約小1/2，質(zhì)量減輕60﹪，轉(zhuǎn)子慣量減到直流電動(dòng)機(jī)的1/5。它與異步電動(dòng)機(jī)相比，由于采用了永磁鐵勵(lì)磁，消除了勵(lì)磁損耗及有關(guān)的雜散損耗，所以效率高。又因?yàn)闆]有電磁式同步電動(dòng)機(jī)所需的集電環(huán)和電刷等，其機(jī)械可靠性與感應(yīng)（異步）電動(dòng)機(jī)相同，而功率因數(shù)卻大大高于異步電動(dòng)機(jī)，從而使永磁同步電動(dòng)機(jī)的體積比異步電動(dòng)機(jī)小些。這是因?yàn)樵诘退贂r(shí)，感應(yīng)（異步）電動(dòng)機(jī)由于功率因數(shù)低，輸出同樣的有功功率時(shí)，它的視在功率卻要大得多，而電動(dòng)機(jī)主要尺寸是據(jù)視在功率而定的。
