伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)主(zhu)要作用(yong)是隨著電(dian)(dian)(dian)(dian)壓的(de)(de)變化控(kong)制(zhi)轉(zhuan)速均勻(yun)穩定，伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)主(zhu)要是靠脈(mo)(mo)(mo)沖(chong)(chong)(chong)來(lai)定位，當(dang)接受到(dao)一個(ge)(ge)脈(mo)(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)(dian)流，就(jiu)(jiu)會相(xiang)應(ying)的(de)(de)旋(xuan)轉(zhuan)一個(ge)(ge)脈(mo)(mo)(mo)沖(chong)(chong)(chong)的(de)(de)對應(ying)角(jiao)度，從而實(shi)現，因為伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)本(ben)身也具有發(fa)出脈(mo)(mo)(mo)沖(chong)(chong)(chong)電(dian)(dian)(dian)(dian)流的(de)(de)功能(neng)，每當(dang)旋(xuan)轉(zhuan)一個(ge)(ge)角(jiao)度都會發(fa)出對應(ying)數(shu)量(liang)的(de)(de)脈(mo)(mo)(mo)沖(chong)(chong)(chong)，和伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)接受的(de)(de)脈(mo)(mo)(mo)沖(chong)(chong)(chong)形成了(le)呼應(ying)，伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)詳情(qing)，或者叫閉環(huan)，如此(ci)一來(lai)，系統就(jiu)(jiu)會知(zhi)道發(fa)了(le)多少脈(mo)(mo)(mo)沖(chong)(chong)(chong)給伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)，同時又(you)收了(le)多少脈(mo)(mo)(mo)沖(chong)(chong)(chong)回(hui)來(lai)，這樣就(jiu)(jiu)能(neng)夠準(zhun)確(que)的(de)(de)控(kong)制(zhi)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)轉(zhuan)動，太原(yuan)伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)，準(zhun)確(que)的(de)(de)定位可以達到(dao)0.001mm。

1、交(jiao)流(liu)伺服(fu)電(dian)(dian)機(ji)(ji)也是無刷電(dian)(dian)機(ji)(ji)，分為同(tong)步和異步電(dian)(dian)機(ji)(ji)，運(yun)動(dong)控(kong)制(zhi)中一般都用(yong)同(tong)步電(dian)(dian)機(ji)(ji)，它的(de)功率(lv)范圍大(da)，伺服(fu)電(dian)(dian)機(ji)(ji)廠家，可以(yi)做到很大(da)的(de)功率(lv)。大(da)慣量，轉(zhuan)動(dong)速度(du)低(di)，且隨(sui)著功率(lv)增大(da)而快速降低(di)。因而適(shi)合做低(di)速平穩運(yun)行的(de)應用(yong)。2、伺服(fu)電(dian)(dian)機(ji)(ji)內部的(de)轉(zhuan)子是永(yong)磁鐵(tie)，驅動(dong)器(qi)(qi)控(kong)制(zhi)的(de)U/V/W三相(xiang)電(dian)(dian)形成電(dian)(dian)磁場(chang)，轉(zhuan)子在此磁場(chang)的(de)作用(yong)下轉(zhuan)動(dong)，同(tong)時電(dian)(dian)機(ji)(ji)自帶(dai)的(de)編(bian)碼器(qi)(qi)反饋信號給驅動(dong)器(qi)(qi)，驅動(dong)器(qi)(qi)根(gen)據(ju)反饋值(zhi)與目標值(zhi)進行比較(jiao)，調整轉(zhuan)子轉(zhuan)動(dong)的(de)角度(du)。伺服(fu)電(dian)(dian)機(ji)(ji)的(de)精度(du)決定于編(bian)碼器(qi)(qi)的(de)精度(du)（線(xian)數）。

伺(si)(si)服(fu)電(dian)機(ji)怎么安(an)裝？1.另外對驅動軸(zhou)設計(ji)方案，在確保彎折抗壓強度(du)及扭曲抗壓強度(du)狀況下流提升。明確軸(zhou)徑后(hou)，選(xuan)軸(zhou)承尺寸及相(xiang)互配合制(zhi)。較(jiao)后(hou)進行(xing)軸(zhou)的(de)總(zong)體(ti)設計(ji)。2.明確伺(si)(si)服(fu)電(dian)機(ji)及減速機(ji)的(de)安(an)裝方法，3.伺(si)(si)服(fu)電(dian)機(ji)操縱用微型機(ji)usb轉232串口就能夠操縱，伺(si)(si)服(fu)電(dian)機(ji)咨(zi)詢，或是選(xuan)用can系(xi)統(tong)總(zong)線。上位機(ji)軟件能夠選(xuan)用VB或labview等服(fu)務平臺電(dian)腦編程。伺(si)(si)服(fu)電(dian)機(ji)提議用空(kong)心(xin)杯電(dian)機(ji)，沒有響應(ying)快，動能使用率(lv)高，轉距(ju)穩定(ding)。
