首(shou)先(xian)，伺(si)服電機是可以帶(dai)載(zai)(zai)的，它(ta)的過載(zai)(zai)能力較強，對負載(zai)(zai)變化(hua)適應良好。

其次，伺服電機最大允許的(de)負載(zai)通常情況下是電機本身功率的(de)1.5倍以(yi)上。

再次，伺服電機的(de)負載大小取決于(yu)電機的(de)最大允許輸出(chu)扭矩和(he)(he)轉速，以及(ji)負載本身的(de)慣量大小和(he)(he)摩(mo)擦阻力等因素。

結尾，伺(si)服(fu)電機(ji)(ji)的(de)(de)過(guo)(guo)載(zai)(zai)能(neng)(neng)(neng)力(li)一(yi)般(ban)是指其能(neng)(neng)(neng)夠在超過(guo)(guo)額定負載(zai)(zai)的(de)(de)情(qing)況下運(yun)行(xing)一(yi)段時間的(de)(de)能(neng)(neng)(neng)力(li)，但(dan)過(guo)(guo)載(zai)(zai)運(yun)行(xing)可能(neng)(neng)(neng)會導致電機(ji)(ji)過(guo)(guo)熱甚至損壞等(deng)情(qing)況，因(yin)此(ci)在實(shi)際應用中需要根據(ju)具體情(qing)況進行(xing)選擇和調整。伺(si)服(fu)電機(ji)(ji)控制可以通(tong)(tong)過(guo)(guo)外部(bu)控制器或內部(bu)控制功(gong)能(neng)(neng)(neng)實(shi)現，而非伺(si)服(fu)電機(ji)(ji)則通(tong)(tong)常通(tong)(tong)過(guo)(guo)電機(ji)(ji)驅動器實(shi)現。浙江英威騰DA300伺(si)服(fu)電機(ji)(ji)線纜

伺服電(dian)動(dong)機與普(pu)通電(dian)動(dong)機的區別如下：

伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)能夠做到控制(zhi)(zhi)，可以(yi)控制(zhi)(zhi)讓(rang)轉多少(shao)就轉多少(shao)，而普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)轉速過快，扭力過小(xiao)，自(zi)身沒有(you)反饋，所(suo)以(yi)沒辦法做到的控制(zhi)(zhi)。伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)是(shi)(shi)經(jing)過經(jing)過反應(ying)(ying)編碼器(qi)(qi)(qi)的同步(bu)信號(hao)知道(dao)轉子改換的磁場，所(suo)以(yi)能夠完成控制(zhi)(zhi)，但是(shi)(shi)普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)沒有(you)同步(bu)信號(hao)要求。伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的結(jie)構是(shi)(shi)閉(bi)環反饋控制(zhi)(zhi)，需要使用(yong)伺(si)服驅(qu)(qu)動(dong)器(qi)(qi)(qi)，但是(shi)(shi)普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)結(jie)構相(xiang)對來(lai)說比較簡(jian)單。伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的價(jia)格(ge)通(tong)常要比普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)機(ji)更(geng)貴，而且故(gu)障類(lei)型更(geng)多，維修更(geng)麻煩(fan)。普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)的應(ying)(ying)用(yong)場合主要是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動(dong)玩具、剃須刀之類(lei)的普(pu)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，而伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)需求經(jing)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)后端的傳感器(qi)(qi)(qi)及編碼器(qi)(qi)(qi)反應(ying)(ying)速度、方位或力矩(ju)參考值(zhi)給配套驅(qu)(qu)動(dong)器(qi)(qi)(qi)，再(zai)由驅(qu)(qu)動(dong)器(qi)(qi)(qi)實(shi)時調(diao)整驅(qu)(qu)動(dong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)按用(yong)戶指定值(zhi)來(lai)操控電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)旋轉。7.5KW伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)慣量(liang)伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)可以(yi)適用(yong)于各種不(bu)同的應(ying)(ying)用(yong)場合。根據(ju)不(bu)同的需求，可以(yi)選擇不(bu)同類(lei)型的伺(si)服電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)。

伺(si)服電(dian)機(ji)跟脈(mo)(mo)沖(chong)(chong)(chong)有密切的(de)(de)關系(xi)。伺(si)服電(dian)機(ji)主(zhu)要靠脈(mo)(mo)沖(chong)(chong)(chong)來定位。當伺(si)服電(dian)機(ji)接(jie)收到(dao)1個脈(mo)(mo)沖(chong)(chong)(chong)，就(jiu)(jiu)會旋轉(zhuan)1個脈(mo)(mo)沖(chong)(chong)(chong)對(dui)應(ying)的(de)(de)角度，從而(er)實現位移(yi)。伺(si)服電(dian)機(ji)本身具備發(fa)出(chu)脈(mo)(mo)沖(chong)(chong)(chong)的(de)(de)功能(neng)，所以伺(si)服電(dian)機(ji)每旋轉(zhuan)一個角度，都會發(fa)出(chu)對(dui)應(ying)數量的(de)(de)脈(mo)(mo)沖(chong)(chong)(chong)和伺(si)服電(dian)機(ji)接(jie)受的(de)(de)脈(mo)(mo)沖(chong)(chong)(chong)形成了(le)呼應(ying)，或者叫閉(bi)環，系(xi)統就(jiu)(jiu)會知道(dao)發(fa)了(le)多少(shao)脈(mo)(mo)沖(chong)(chong)(chong)給(gei)伺(si)服電(dian)機(ji)，同時又收了(le)多少(shao)脈(mo)(mo)沖(chong)(chong)(chong)回來，就(jiu)(jiu)能(neng)夠很精確的(de)(de)控(kong)制電(dian)機(ji)的(de)(de)轉(zhuan)動，從而(er)實現精確的(de)(de)定位。

可(ke)以通(tong)過(guo)以下方(fang)法判(pan)斷伺(si)(si)服(fu)電(dian)機驅動器(qi)(qi)是否丟(diu)脈(mo)(mo)沖：使用(yong)示波(bo)器(qi)(qi)測(ce)(ce)(ce)(ce)量(liang)(liang)(liang)。將示波(bo)器(qi)(qi)的(de)(de)探頭(tou)分別連接伺(si)(si)服(fu)控(kong)制器(qi)(qi)的(de)(de)丟(diu)脈(mo)(mo)沖輸出端(duan)和編(bian)(bian)碼器(qi)(qi)反饋端(duan)，觀察(cha)示波(bo)器(qi)(qi)的(de)(de)顯示信(xin)(xin)號(hao)，通(tong)過(guo)測(ce)(ce)(ce)(ce)量(liang)(liang)(liang)信(xin)(xin)號(hao)的(de)(de)周期和脈(mo)(mo)寬來計(ji)算伺(si)(si)服(fu)丟(diu)脈(mo)(mo)沖的(de)(de)情況。使用(yong)編(bian)(bian)碼器(qi)(qi)測(ce)(ce)(ce)(ce)量(liang)(liang)(liang)。將編(bian)(bian)碼器(qi)(qi)連接到伺(si)(si)服(fu)電(dian)機軸上，并(bing)將編(bian)(bian)碼器(qi)(qi)的(de)(de)輸出信(xin)(xin)號(hao)接到伺(si)(si)服(fu)控(kong)制器(qi)(qi)上，使用(yong)編(bian)(bian)碼器(qi)(qi)測(ce)(ce)(ce)(ce)試儀測(ce)(ce)(ce)(ce)量(liang)(liang)(liang)編(bian)(bian)碼器(qi)(qi)輸出信(xin)(xin)號(hao)，并(bing)記錄下每個周期的(de)(de)脈(mo)(mo)沖數和方(fang)向(xiang)，通(tong)過(guo)比較測(ce)(ce)(ce)(ce)量(liang)(liang)(liang)結果和理論值，判(pan)斷伺(si)(si)服(fu)系統是否存在(zai)丟(diu)脈(mo)(mo)沖的(de)(de)情況。

伺(si)服電動機應具備以(yi)下基(ji)本(ben)要(yao)求：

寬廣的(de)(de)調速(su)范圍：伺服電機(ji)應(ying)能夠(gou)(gou)在速(su)度范圍內進行平滑的(de)(de)調節。無論(lun)是(shi)在低(di)速(su)還是(shi)高速(su)，電機(ji)都(dou)應(ying)能夠(gou)(gou)穩(wen)定(ding)運行，并(bing)且能夠(gou)(gou)實(shi)現精確的(de)(de)速(su)度控(kong)制。

快(kuai)速(su)響應：伺(si)服電(dian)機應具有快(kuai)速(su)的(de)響應能(neng)力，能(neng)夠在(zai)短時(shi)間內(nei)達(da)到所需的(de)轉(zhuan)速(su)和扭矩。這對于需要快(kuai)速(su)動(dong)作的(de)應用(yong)來說非常(chang)重要，例如在(zai)工業自動(dong)化(hua)生產線上的(de)定位控制或者機器人的(de)運動(dong)控制。

精確(que)控制：伺服電(dian)機應(ying)能夠實(shi)現(xian)精確(que)的速(su)度和位(wei)(wei)置控制。電(dian)機的速(su)度和位(wei)(wei)置應(ying)與輸入(ru)的控制信號準(zhun)確(que)對應(ying)，從而實(shi)現(xian)高(gao)精度的運動控制。

穩定性：伺服(fu)電機(ji)應(ying)能(neng)夠在各(ge)種工(gong)作條(tiao)件下(xia)保(bao)持(chi)穩定的(de)(de)運行狀態。無(wu)論是在負(fu)載變化、環境溫度變化還是電源波動(dong)的(de)(de)情況下(xia)，電機(ji)都(dou)應(ying)能(neng)夠保(bao)持(chi)穩定的(de)(de)轉速和扭矩輸出。

耐用性和可靠性：伺服電機應具有(you)較高的耐用性和可靠性，能夠長時間地在高負(fu)載(zai)和高頻率的環境下工作，并且不(bu)需要頻繁(fan)的維護(hu)和更換部件。

易(yi)于安裝和(he)(he)(he)維護(hu)：伺(si)服(fu)電機應具有(you)簡單的安裝和(he)(he)(he)維護(hu)要求，方便用戶進行安裝和(he)(he)(he)使用，并且(qie)能夠在需要維護(hu)時方便地進行拆卸(xie)和(he)(he)(he)更換(huan)部件。

伺服電機的(de)故(gu)障診(zhen)斷可以(yi)通過監測電機的(de)溫度、震動(dong)等參(can)數來判斷電機是否正常(chang)工作(zuo)。

伺服(fu)電機(ji)(ji)并不是(shi)必須帶減(jian)速(su)機(ji)(ji)。加(jia)(jia)不加(jia)(jia)減(jian)速(su)機(ji)(ji)是(shi)由客戶使(shi)用的工況(kuang)所(suo)決定的。例如在重載(zai)、高(gao)(gao)精(jing)度(du)、高(gao)(gao)響應、高(gao)(gao)穩(wen)定性等(deng)場(chang)合，有時(shi)需要(yao)使(shi)用減(jian)速(su)機(ji)(ji)來匹配伺服(fu)電機(ji)(ji)的性能，而在一些輕載(zai)、低(di)速(su)、中精(jing)度(du)等(deng)場(chang)合，有時(shi)會(hui)選擇不帶減(jian)速(su)機(ji)(ji)的伺服(fu)電機(ji)(ji)。

需(xu)要使用減(jian)(jian)速機(ji)(ji)(ji)(ji)的(de)情況有：有重(zhong)負(fu)荷高精度(du)(du)需(xu)求時(shi)。比如航空、衛星、醫療、科技(ji)、晶(jing)圓設(she)(she)備(bei)、機(ji)(ji)(ji)(ji)器人等自動(dong)化設(she)(she)備(bei)領(ling)域中。他們所(suo)需(xu)的(de)扭(niu)矩(ju)(ju)(ju)往往遠(yuan)超伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)本身的(de)扭(niu)矩(ju)(ju)(ju)容量，所(suo)以需(xu)要減(jian)(jian)速機(ji)(ji)(ji)(ji)來(lai)提(ti)升伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)輸(shu)出扭(niu)矩(ju)(ju)(ju)。需(xu)要提(ti)高設(she)(she)備(bei)扭(niu)矩(ju)(ju)(ju)時(shi)。設(she)(she)備(bei)如果采用直接(jie)增大(da)(da)伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)輸(shu)出扭(niu)矩(ju)(ju)(ju)的(de)方法，就必(bi)須(xu)用昂貴(gui)大(da)(da)功率的(de)伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)和(he)大(da)(da)功率的(de)驅動(dong)器，成本過大(da)(da)，所(suo)以用減(jian)(jian)速機(ji)(ji)(ji)(ji)更加(jia)合(he)適。需(xu)要提(ti)高設(she)(she)備(bei)使用性能時(shi)。當(dang)設(she)(she)備(bei)負(fu)載(zai)慣量不當(dang)匹配時(shi)，伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)控(kong)制(zhi)(zhi)就會不穩(wen)定(ding)。所(suo)以對于大(da)(da)的(de)負(fu)載(zai)慣量，一(yi)般用減(jian)(jian)速機(ji)(ji)(ji)(ji)的(de)特性來(lai)控(kong)制(zhi)(zhi)更加(jia)的(de)適合(he)。伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)能夠以非常高的(de)精度(du)(du)進行位(wei)置控(kong)制(zhi)(zhi)這種精確(que)控(kong)制(zhi)(zhi)使伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)在需(xu)要精細定(ding)位(wei)的(de)應用領(ling)域中非常重(zhong)要。伺(si)(si)(si)服(fu)(fu)(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)電(dian)(dian)壓
