通常(chang)激光打標機振鏡（包括常見的半(ban)導體(ti)激(ji)光(guang)打標(biao)(biao)機(ji)和二氧化(hua)碳激(ji)光(guang)打標(biao)(biao)機(ji)，光(guang)纖(xian)激(ji)光(guang)打標(biao)(biao)機(ji)）都是由兩部分組成，一(yi)是，控制器；第(di)二是振鏡頭（電機(ji)），那這個振鏡對激(ji)光(guang)打標(biao)(biao)機(ji)的性能有什么影響(xiang)，對激(ji)光(guang)打標(biao)(biao)機(ji)又(you)有什么作(zuo)用呢？
 
1、激光打(da)標機振鏡頭組成：
由定子，轉(zhuan)子，檢測(ce)傳(chuan)感(gan)器(qi)三部(bu)份(fen)組成。其(qi)中振鏡(jing)頭為(wei)(wei)動圈式(shi)（轉(zhuan)子為(wei)(wei)線圈），其(qi)它的(de)(de)(de)均為(wei)(wei)動磁式(shi)（轉(zhuan)子為(wei)(wei)磁芯），所(suo)(suo)有的(de)(de)(de)振鏡(jing)頭均采用為(wei)(wei)永久磁鐵為(wei)(wei)磁芯；檢測(ce)傳(chuan)感(gan)器(qi)模擬振鏡(jing)為(wei)(wei)電容(rong)式(shi)傳(chuan)感(gan)器(qi)，數字振鏡(jing)為(wei)(wei)光(guang)柵(zha)(zha)尺檢測(ce)傳(chuan)感(gan)器(qi)。電容(rong)傳(chuan)感(gan)器(qi)是電機擺動時，檢測(ce)傳(chuan)感(gan)器(qi)的(de)(de)(de)電容(rong)量發生(sheng)微小的(de)(de)(de)變(bian)化，把這電容(rong)的(de)(de)(de)變(bian)化量轉(zhuan)變(bian)為(wei)(wei)電信號(hao)，反饋給(gei)控制器(qi)，從而進行閉環控制。光(guang)柵(zha)(zha)尺傳(chuan)感(gan)器(qi)則(ze)通過光(guang)柵(zha)(zha)尺進行測(ce)量實(shi)際偏轉(zhuan)的(de)(de)(de)角度，從而轉(zhuan)換成電信號(hao)，反饋給(gei)控制器(qi)，進行閉環控制。動圈式(shi)因為(wei)(wei)轉(zhuan)子為(wei)(wei)線圈，而線圈相對來說(shuo)，體(ti)積較(jiao)大(da)，轉(zhuan)動慣(guan)(guan)量大(da)，不利(li)(li)于快速(su)響應(ying)，所(suo)(suo)以(yi)現在基本也不采用。所(suo)(suo)以(yi)說(shuo)動磁式(shi)因空芯柱形磁芯緊裝在轉(zhuan)動軸上，體(ti)積小，慣(guan)(guan)量小，快速(su)響應(ying)性能就很好(hao)，更利(li)(li)于激光(guang)打(da)標(biao)機的(de)(de)(de)高速(su)打(da)標(biao)。
 
2、激(ji)光打標機振鏡電機電動(dong)機的分類：
電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)主要(yao)分為四大類：交流電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，直流電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，交直兩用(yong)(yong)(yong)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，特殊用(yong)(yong)(yong)途電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)。交流電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)包括同步電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)，異(yi)步電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)。特殊用(yong)(yong)(yong)途電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)包括電(dian)(dian)(dian)動(dong)(dong)測功機(ji)(ji)(ji)(ji)，同步調相(xiang)機(ji)(ji)(ji)(ji)、進(jin)相(xiang)機(ji)(ji)(ji)(ji)、微特電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)、其(qi)(qi)它特殊用(yong)(yong)(yong)途電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)。激光打標機(ji)(ji)(ji)(ji)振鏡頭屬于其(qi)(qi)它特殊用(yong)(yong)(yong)途電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)中(zhong)的擺(bai)動(dong)(dong)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)(ji)。
 
3、激光打標機(ji)振鏡(jing)電機(ji)部分的工作(zuo)原理：
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)是(shi)以(yi)(yi)磁(ci)(ci)場(chang)為(wei)媒介(jie)，利(li)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)感(gan)應作用(yong)來(lai)實現能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)轉換的(de)(de)(de)，所以(yi)(yi)其(qi)(qi)內(nei)(nei)部(bu)(bu)一定要有傳導磁(ci)(ci)通(tong)的(de)(de)(de)磁(ci)(ci)路和(he)(he)傳導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)進(jin)行能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)轉換時(shi)，應具備作相對運(yun)動(dong)(dong)的(de)(de)(de)兩大部(bu)(bu)件(jian)(jian)：即建(jian)立勵磁(ci)(ci)磁(ci)(ci)場(chang)的(de)(de)(de)部(bu)(bu)件(jian)(jian)和(he)(he)被感(gan)應部(bu)(bu)件(jian)(jian)，運(yun)動(dong)(dong)的(de)(de)(de)稱(cheng)為(wei)轉子(zi)，靜止的(de)(de)(de)稱(cheng)為(wei)定子(zi)。發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)從機(ji)(ji)(ji)械(xie)(xie)系(xi)統(tong)(tong)(tong)吸收機(ji)(ji)(ji)械(xie)(xie)功(gong)(gong)率(lv)，向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)(tong)輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)功(gong)(gong)率(lv)；電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)統(tong)(tong)(tong)吸收電(dian)(dian)(dian)(dian)(dian)(dian)(dian)功(gong)(gong)率(lv)，向(xiang)機(ji)(ji)(ji)械(xie)(xie)系(xi)統(tong)(tong)(tong)輸(shu)出(chu)(chu)機(ji)(ji)(ji)械(xie)(xie)功(gong)(gong)率(lv)。在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)內(nei)(nei)部(bu)(bu)能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)轉換過程中，存(cun)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)、機(ji)(ji)(ji)械(xie)(xie)能(neng)(neng)(neng)(neng)(neng)(neng)、磁(ci)(ci)場(chang)能(neng)(neng)(neng)(neng)(neng)(neng)和(he)(he)熱能(neng)(neng)(neng)(neng)(neng)(neng)，其(qi)(qi)中熱能(neng)(neng)(neng)(neng)(neng)(neng)是(shi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)內(nei)(nei)部(bu)(bu)能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)損(sun)(sun)耗(hao)(hao)產生的(de)(de)(de)，設計時(shi)盡量(liang)減小。對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)而言,從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源輸(shu)入(ru)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng)=耦(ou)合電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)內(nei)(nei)儲能(neng)(neng)(neng)(neng)(neng)(neng)增(zeng)量(liang)+電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)內(nei)(nei)部(bu)(bu)損(sun)(sun)耗(hao)(hao)能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)+輸(shu)出(chu)(chu)的(de)(de)(de)機(ji)(ji)(ji)械(xie)(xie)能(neng)(neng)(neng)(neng)(neng)(neng),對發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)而言,從機(ji)(ji)(ji)械(xie)(xie)系(xi)統(tong)(tong)(tong)輸(shu)入(ru)的(de)(de)(de)機(ji)(ji)(ji)械(xie)(xie)能(neng)(neng)(neng)(neng)(neng)(neng)=耦(ou)合電(dian)(dian)(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)場(chang)內(nei)(nei)儲能(neng)(neng)(neng)(neng)(neng)(neng)增(zeng)量(liang)+電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)內(nei)(nei)部(bu)(bu)損(sun)(sun)耗(hao)(hao)能(neng)(neng)(neng)(neng)(neng)(neng)量(liang)+輸(shu)出(chu)(chu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)(neng)(neng)(neng) 。
 
終結，用在激光打標機里，對振(zhen)(zhen)鏡(jing)的(de)(de)要求是什么呢(ni)？因為(wei)激光打(da)標(biao)(biao)機(ji)是靠X，Y振(zhen)(zhen)偏轉的(de)(de)配(pei)合，將(jiang)光反射到(dao)工(gong)作(zuo)臺(tai)面上，進行精確的(de)(de)雕刻。而振(zhen)(zhen)鏡(jing)的(de)(de)控制是由計算機(ji)開(kai)環控制的(de)(de)。所以(yi)要求必須(xu)為(wei)線性，即輸入(ru)信號同偏轉角度(du)之間為(wei)線性關系。因振(zhen)(zhen)鏡(jing)是快速精密(mi)機(ji)械，所以(yi)要求從一個工(gong)作(zuo)狀(zhuang)態(tai)到(dao)另(ling)一個工(gong)作(zuo)狀(zhuang)態(tai)要求加速度(du)越大越好(hao)，這樣，激光打(da)標(biao)(biao)機(ji)的(de)(de)打(da)標(biao)(biao)空等時間就無(wu)限小。
