電(dian)(dian)(dian)(dian)機帶剎(cha)車(che)，在(zai)(zai)實(shi)際(ji)使(shi)用(yong)中為帶磁抱(bao)閘(zha)電(dian)(dian)(dian)(dian)機，作用(yong)是(shi)電(dian)(dian)(dian)(dian)機得(de)電(dian)(dian)(dian)(dian)啟動(dong)運轉的同時，電(dian)(dian)(dian)(dian)機抱(bao)閘(zha)先得(de)電(dian)(dian)(dian)(dian)松(song)開抱(bao)閘(zha)，電(dian)(dian)(dian)(dian)機再啟動(dong)運行(xing)。當電(dian)(dian)(dian)(dian)機失電(dian)(dian)(dian)(dian)時，抱(bao)閘(zha)也失電(dian)(dian)(dian)(dian)起制動(dong)作用(yong)，使(shi)得(de)電(dian)(dian)(dian)(dian)機快速(su)停止運轉。一(yi)般來說(shuo)剎(cha)車(che)制動(dong)系統和(he)電(dian)(dian)(dian)(dian)北抱(bao)閘(zha)線圈(quan)，都(dou)是(shi)跟(gen)電(dian)(dian)(dian)(dian)機轉子同軸安裝(zhuang)在(zai)(zai)一(yi)塊。直線模組電(dian)(dian)(dian)(dian)機裝(zhuang)剎(cha)車(che)在(zai)(zai)現實(shi)使(shi)用(yong)過(guo)程中，一(yi)般來說(shuo)在(zai)(zai)垂直使(shi)用(yong)過(guo)程中帶剎(cha)車(che)。

 電機(ji)(ji)(ji)(ji)帶剎(cha)車(che)簡單的可(ke)以看作是在電機(ji)(ji)(ji)(ji)的尾部(bu)(bu)安(an)裝相應(ying)(ying)的剎(cha)車(che)裝置(zhi)，電機(ji)(ji)(ji)(ji)尾部(bu)(bu)的這些剎(cha)車(che)裝置(zhi)能在電機(ji)(ji)(ji)(ji)完成工作以后快速的制停電機(ji)(ji)(ji)(ji)的多余(yu)工作。在有些實際的應(ying)(ying)用場合(he)，需電機(ji)(ji)(ji)(ji)的剎(cha)車(che)實現即制停的效果。

 伺服電機帶(dai)(dai)不帶(dai)(dai)剎車有(you)什么區別？

 雖然，伺服(fu)電機(ji)(ji)帶(dai)(dai)不(bu)(bu)帶(dai)(dai)剎(cha)車(che)這些問題，很多人(ren)會被這個問題所造(zao)成困(kun)擾，主(zhu)要(yao)(yao)是因(yin)為帶(dai)(dai)剎(cha)車(che)的(de)(de)電機(ji)(ji)要(yao)(yao)比(bi)不(bu)(bu)帶(dai)(dai)剎(cha)車(che)的(de)(de)電機(ji)(ji)貴得多，大(da)多數貴上百或都(dou)上千，因(yin)此能讓(rang)人(ren)糾結。

 伺服(fu)電(dian)機(ji)(ji)一般具有制(zhi)(zhi)(zhi)動功能，即(ji)根據伺服(fu)系(xi)統的(de)外部指令，利用驅動器快速制(zhi)(zhi)(zhi)動電(dian)機(ji)(ji)。制(zhi)(zhi)(zhi)動通(tong)(tong)常是(shi)枉(wang)費伺服(fu)電(dian)機(ji)(ji)后端的(de)電(dian)磁機(ji)(ji)械制(zhi)(zhi)(zhi)裝置(zhi)，安(an)裝于(yu)電(dian)機(ji)(ji)后端。在(zai)工作(zuo)過(guo)程中，電(dian)機(ji)(ji)通(tong)(tong)過(guo)作(zuo)用在(zai)電(dian)機(ji)(ji)主(zhu)軸上的(de)制(zhi)(zhi)(zhi)動片制(zhi)(zhi)(zhi)動并控(kong)制(zhi)(zhi)(zhi)電(dian)機(ji)(ji)主(zhu)軸。這樣就(jiu)能保護(hu)伺服(fu)電(dian)機(ji)(ji)，使其在(zai)停(ting)電(dian)的(de)情形下保證安(an)全。

 因此選擇(ze)是(shi)否帶(dai)剎車(che)功能的伺服是(shi)電機，主要(yao)(yao)還是(shi)看具體(ti)的需要(yao)(yao)，要(yao)(yao)不(bu)是(shi)必(bi)要(yao)(yao)的話，可以考慮(lv)不(bu)帶(dai)剎車(che)的伺服電機，而(er)且現在帶(dai)剎車(che)的要(yao)(yao)比不(bu)帶(dai)剎車(che)貴太多。
