伺服(fu)電機的(de)速(su)度決定的(de)產品生(sheng)產的(de)成(cheng)果(guo)及(ji)用途，太(tai)快可能(neng)做(zuo)成(cheng)一個(ge)產品，太(tai)慢可能(neng)又(you)是另外(wai)一種產品，因此(ci)必須控(kong)制(zhi)好它的(de)快慢。那么(me)怎么(me)控(kong)制(zhi)伺服(fu)電機的(de)速(su)度呢(ni)？下面康瑞(rui)數控(kong)為大家分享具體(ti)方法。

伺服電機速度怎么控制？

1.伺服電(dian)(dian)機(ji)是(shi)一(yi)(yi)個典型性閉環控(kong)制(zhi)反饋機(ji)制(zhi)，降速傳(chuan)動(dong)齒(chi)輪(lun)組(zu)(zu)由電(dian)(dian)機(ji)驅動(dong)器，其終端(duan)設備推動(dong)一(yi)(yi)個線形的占比電(dian)(dian)阻器作部位(wei)檢驗，該電(dian)(dian)阻器把拐角坐標(biao)轉換為(wei)一(yi)(yi)占比工(gong)作電(dian)(dian)壓意見反饋給控(kong)制(zhi)pcb線路板(ban)，控(kong)制(zhi)pcb線路板(ban)將(jiang)其與(yu)(yu)鍵入的控(kong)制(zhi)差(cha)分信號較(jiao)為(wei)，造成改(gai)正(zheng)單(dan)脈(mo)(mo)沖，并驅動(dong)器電(dian)(dian)動(dong)機(ji)順向(xiang)或反向(xiang)地(di)旋轉，使(shi)傳(chuan)動(dong)齒(chi)輪(lun)組(zu)(zu)的輸出(chu)部位(wei)與(yu)(yu)期待相符合，令改(gai)正(zheng)單(dan)脈(mo)(mo)沖趨(qu)向(xiang)為(wei)0，進(jin)而(er)超過使(shi)伺服電(dian)(dian)機(ji)精準(zhun)定(ding)位(wei)與(yu)(yu)定(ding)速的目地(di)。

2.一般(ban)伺服電機常有(you)三種(zhong)控(kong)制(zhi)(zhi)方(fang)(fang)(fang)法(fa)：速(su)度控(kong)制(zhi)(zhi)方(fang)(fang)(fang)法(fa)，轉距控(kong)制(zhi)(zhi)方(fang)(fang)(fang)法(fa)，部位控(kong)制(zhi)(zhi)方(fang)(fang)(fang)法(fa)。

假(jia)(jia)(jia)如(ru)(ru)您對(dui)電動(dong)機的速(su)(su)度(du)、部位(wei)也沒(mei)有(you)(you)規(gui)定(ding)，要是輸出一(yi)個(ge)恒轉距，或許是用(yong)(yong)轉距方(fang)式(shi)(shi)。假(jia)(jia)(jia)如(ru)(ru)對(dui)部位(wei)和速(su)(su)度(du)有(you)(you)一(yi)定(ding)的精密度(du)規(gui)定(ding)，而(er)對(dui)即時(shi)轉距并(bing)不是很關注，用(yong)(yong)轉距方(fang)式(shi)(shi)不太(tai)便捷，用(yong)(yong)速(su)(su)度(du)或部位(wei)方(fang)式(shi)(shi)較為好。假(jia)(jia)(jia)如(ru)(ru)上臺(tai)控(kong)制器(qi)有(you)(you)較為好的閉環控(kong)制控(kong)制作用(yong)(yong)，用(yong)(yong)速(su)(su)度(du)控(kong)制實(shi)際效果會好一(yi)點。假(jia)(jia)(jia)如(ru)(ru)自身規(gui)定(ding)并(bing)不是很高，或是，基(ji)礎(chu)沒(mei)有(you)(you)實(shi)用(yong)(yong)性的規(gui)定(ding)，用(yong)(yong)部位(wei)控(kong)制方(fang)法對(dui)上臺(tai)控(kong)制器(qi)沒(mei)有(you)(you)很高的規(gui)定(ding)。

3.就伺服(fu)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)的(de)(de)(de)沒有(you)響(xiang)(xiang)應(ying)速(su)(su)(su)(su)度(du)(du)看來，轉距方(fang)式(shi)運算量(liang)較(jiao)少(shao)，控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)對控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)數據信(xin)號(hao)的(de)(de)(de)沒有(you)響(xiang)(xiang)應(ying)更快(kuai);部位(wei)(wei)方(fang)式(shi)運算量(liang)較(jiao)大，控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)對控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)數據信(xin)號(hao)的(de)(de)(de)沒有(you)響(xiang)(xiang)應(ying)比較(jiao)慢。對健(jian)身運動(dong)(dong)中的(de)(de)(de)動(dong)(dong)態(tai)性(xing)特性(xing)有(you)較(jiao)為(wei)高的(de)(de)(de)規定時(shi)，必須即時(shi)對電動(dong)(dong)機開(kai)展調節。那(nei)(nei)麼假如控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)自身的(de)(de)(de)與運算速(su)(su)(su)(su)度(du)(du)比較(jiao)慢就用部位(wei)(wei)方(fang)法控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)。假如控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)與運算速(su)(su)(su)(su)度(du)(du)較(jiao)為(wei)快(kuai)，能夠用速(su)(su)(su)(su)度(du)(du)方(fang)法，把部位(wei)(wei)環從(cong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)挪到控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)上，降低控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)的(de)(de)(de)勞動(dong)(dong)量(liang)，提高工作效率；假如有(you)更強的(de)(de)(de)上臺控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)，可以(yi)用轉距方(fang)法控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)，把速(su)(su)(su)(su)度(du)(du)環也從(cong)控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)移位(wei)(wei)開(kai)，這一般僅僅高檔專用型控(kong)(kong)(kong)制(zhi)(zhi)(zhi)(zhi)(zhi)器(qi)(qi)才可以(yi)那(nei)(nei)么干，并且，這時(shi)候徹底(di)不(bu)用應(ying)用伺服(fu)電機。

以上就是(shi)深圳(zhen)康瑞數控(kong)為大家帶來的“伺服電(dian)機速度(du)快慢控(kong)制(zhi)方(fang)法”分享，希望能對您有所幫助。這里大家知(zhi)道(dao)，想要(yao)控(kong)制(zhi)好速度(du)就必須掌(zhang)握好三個方(fang)式，即(ji)：速度(du)、轉矩和位置。
