style="text-indent:25px">影響伺服電機(jī)正常運(yùn)行的因素：1、機(jī)械共振。機(jī)械共振問(wèn)題對(duì)伺服較大的影響在于無(wú)法繼續(xù)提高伺服電機(jī)的響應(yīng)性，從而使設(shè)備整體運(yùn)行在比較低的響應(yīng)狀態(tài)。此類問(wèn)題在同步帶傳動(dòng)的機(jī)械中比較常見(jiàn)，另外長(zhǎng)距離的滾珠絲桿有時(shí)也有此類情況。主要原因是同步帶的剛性偏低，共振頻率低，長(zhǎng)距離的絲桿自身慣量較大，且多有變形情況，特別是在電機(jī)容量選擇偏小的情況下比較容易起振。同時(shí)安裝時(shí)的裝配工藝高低和材質(zhì)的優(yōu)劣也會(huì)對(duì)機(jī)械的共振產(chǎn)生影響。2、數(shù)控系統(tǒng)因素。有的情況下，伺服的調(diào)試效果不明顯，此時(shí)可能就要介入對(duì)控制系統(tǒng)的調(diào)節(jié)了。激光切割機(jī)加工時(shí)通常線速度是比較恒定的，在直線與曲線上都是同一速度。這一點(diǎn)在直線運(yùn)動(dòng)上是沒(méi)有多大問(wèn)題的，但是在曲線，特別是小尺寸圓弧的加工上可能會(huì)因?yàn)榧铀俣冗^(guò)大導(dǎo)致輪廓變形的情況。3、機(jī)械抖動(dòng)。機(jī)械抖動(dòng)實(shí)質(zhì)也是機(jī)械的固有頻率問(wèn)題，通常比較多地出現(xiàn)在單端固定的懸梁結(jié)構(gòu)中，特別是在加減速階段表現(xiàn)尤其明顯。低頻的抖動(dòng)在加工件中會(huì)呈現(xiàn)出波浪狀的形態(tài)，較高頻的抖動(dòng)會(huì)有鋸齒狀的形態(tài)。上海交流同步伺服電機(jī)口碑電動(dòng)機(jī)應(yīng)具有大的較長(zhǎng)時(shí)間的過(guò)載能力，以滿足低速大轉(zhuǎn)矩的要求。</p><div

style="text-indent:25px">永磁同步伺服電機(jī)是由繞線式同步電機(jī)發(fā)展而來(lái)，它用永磁體代替了電勵(lì)磁，從而省去了勵(lì)磁線圈、滑環(huán)與電刷，其定子電流與繞線式同步電機(jī)基本相同，輸入為對(duì)稱正弦交流電，故稱為交流永磁同步伺服電機(jī)。永磁同步伺服電機(jī)由定子和轉(zhuǎn)子兩部分構(gòu)成。定子主要包括電樞鐵心和三相(或多相)對(duì)稱電樞繞組，繞組嵌放在鐵心的槽中；轉(zhuǎn)子主要由永磁體、導(dǎo)磁軛和轉(zhuǎn)軸構(gòu)成。永磁體貼在導(dǎo)磁軛上，導(dǎo)磁軛為圓筒形，套在轉(zhuǎn)軸上；當(dāng)轉(zhuǎn)子的直徑較小時(shí)，可以直接把永磁體貼在導(dǎo)磁軸上。轉(zhuǎn)子同軸連接有位置、速度傳感器，用于檢測(cè)轉(zhuǎn)子磁極相對(duì)于定子繞組的相對(duì)位置以及轉(zhuǎn)子轉(zhuǎn)速。當(dāng)永磁同步伺服電機(jī)的電樞繞組中通過(guò)對(duì)稱的三相電流時(shí)，定子將產(chǎn)生一個(gè)以同步轉(zhuǎn)速推移的旋轉(zhuǎn)磁場(chǎng)。在穩(wěn)態(tài)情況下，轉(zhuǎn)子的轉(zhuǎn)速恒為磁場(chǎng)的同步轉(zhuǎn)速。</p><p style="text-indent:25px">伺服電機(jī)的編碼器一般有相對(duì)值編碼器和相對(duì)值編碼器兩種，其中，相對(duì)值編碼器可以保持?jǐn)嚯姞顟B(tài)，只要電池有電，就不需要尋原點(diǎn)；相對(duì)碼器則因斷電會(huì)丟失電機(jī)的多圈數(shù)值，所以需要尋原點(diǎn)操作。相位編碼器伺服電機(jī)在尋原點(diǎn)過(guò)程中需要一個(gè)外部傳感器來(lái)配合動(dòng)作，當(dāng)外部傳感器檢測(cè)到尋原點(diǎn)位置塊后，伺服電機(jī)由尋原點(diǎn)高速切換到尋原點(diǎn)低速，當(dāng)外部傳感器檢測(cè)到下降沿后，伺服電機(jī)轉(zhuǎn)到編碼器Z相輸出點(diǎn)，但其中幾點(diǎn)是要特別注意的：一、伺服馬達(dá)后部的編碼器如安裝牢固，Z相脈沖點(diǎn)固定，伺服尋原點(diǎn)也十分精確；二是伺服馬達(dá)尋原點(diǎn)方式多種多樣，需要根據(jù)現(xiàn)場(chǎng)設(shè)備確定馬達(dá)在各工序的運(yùn)行方向；三、原點(diǎn)的精度不取決于外部傳感器的精度，只要外部傳感器沒(méi)有松動(dòng)，伺服馬達(dá)應(yīng)該能夠非常精確地找到原點(diǎn)；四、一般而言，伺服電機(jī)尋原點(diǎn)的目的是使電機(jī)當(dāng)前實(shí)際位置與控制器內(nèi)位置相匹配，因此，許多伺服電機(jī)尋原點(diǎn)較終停止位置不在0.0的位置，會(huì)有一點(diǎn)偏差，這并不表示尋原點(diǎn)位置有誤差，而是由于電機(jī)的實(shí)際位置已與控制器內(nèi)位置相匹配，所以不必精確地回到原點(diǎn)。伺服電機(jī)優(yōu)點(diǎn)：永磁體它位于轉(zhuǎn)子內(nèi)部，轉(zhuǎn)子的結(jié)構(gòu)簡(jiǎn)單、機(jī)械強(qiáng)度高、制造成本低。</p><div
