選擇變(bian)頻器跟伺服(fu)電機的方法如(ru)下：

確認(ren)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)參(can)(can)數(shu)(shu)：如額(e)定(ding)功率、額(e)定(ding)電(dian)(dian)(dian)(dian)壓(ya)、額(e)定(ding)電(dian)(dian)(dian)(dian)流(liu)等。選擇(ze)合適(shi)的(de)(de)變(bian)頻器(qi)和(he)伺(si)服電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)時(shi)要(yao)根據電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)參(can)(can)數(shu)(shu)進行搭配，否則會(hui)導致(zhi)設備不能正常(chang)工作。選擇(ze)合適(shi)的(de)(de)類型：用(yong)戶可以(yi)(yi)(yi)根據自己的(de)(de)實際工藝要(yao)求和(he)運用(yong)場合選擇(ze)不同類型的(de)(de)變(bian)頻器(qi)。考慮(lv)變(bian)頻器(qi)的(de)(de)輸(shu)出(chu)：變(bian)頻器(qi)的(de)(de)輸(shu)出(chu)含(han)有豐富的(de)(de)高次諧波，會(hui)使電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)功率因數(shu)(shu)和(he)效率變(bian)壞。因此，用(yong)變(bian)頻器(qi)給電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)供(gong)電(dian)(dian)(dian)(dian)與用(yong)工頻電(dian)(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)(dian)相比(bi)較(jiao)，電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)會(hui)增加10%而溫(wen)升(sheng)會(hui)增加20%左右。所以(yi)(yi)(yi)在選擇(ze)電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)和(he)變(bian)頻器(qi)時(shi)，應考慮(lv)到(dao)這種(zhong)情況，適(shi)當留有余量，以(yi)(yi)(yi)防止溫(wen)升(sheng)過高，影(ying)響電(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)的(de)(de)使用(yong)壽(shou)命(ming)。基本上，伺(si)服電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)是由一個電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、一個編碼器(qi)和(he)一個電(dian)(dian)(dian)(dian)子控(kong)制器(qi)組成。浙江(jiang)伺(si)服電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)安裝(zhuang)

伺(si)服電(dian)機驅動(dong)器(qi)不能(neng)直接在三相異(yi)(yi)步電(dian)機上使(shi)用(yong)(yong)。三相異(yi)(yi)步電(dian)機與伺(si)服電(dian)機的運行原理、結(jie)構(gou)、使(shi)用(yong)(yong)要求等都有所不同，因此不能(neng)使(shi)用(yong)(yong)伺(si)服電(dian)機驅動(dong)器(qi)來驅動(dong)三相異(yi)(yi)步電(dian)機。

因為(wei)三相異步電(dian)機(ji)無法提供(gong)高精度的(de)位置(zhi)控(kong)制和(he)(he)高速(su)度運(yun)動(dong)的(de)性能，相比之下伺服電(dian)機(ji)更為(wei)適用(yong)。如果需要實現高速(su)度、高精度、高加速(su)度和(he)(he)高扭矩(ju)的(de)運(yun)動(dong)控(kong)制，建議使用(yong)伺服電(dian)機(ji)。而(er)對于一些(xie)簡單的(de)運(yun)動(dong)控(kong)制，如機(ji)器人的(de)基礎運(yun)動(dong)和(he)(he)一些(xie)簡單的(de)傳送裝置(zhi)的(de)驅動(dong)，三相異步電(dian)機(ji)以其結構簡單、價格便宜、可靠性高的(de)特點更為(wei)適用(yong)。

浙江(jiang)英威騰IMS20A伺(si)服電(dian)機(ji)尺寸伺(si)服驅動器和伺(si)服電(dian)機(ji)匹配時(shi)，要檢查額定電(dian)流和電(dian)壓(ya)。

伺(si)服(fu)(fu)驅(qu)動(dong)器(qi)(qi)和(he)(he)伺(si)服(fu)(fu)電(dian)機(ji)(ji)(ji)(ji)是兩個不同(tong)(tong)的(de)設(she)備，它們的(de)作(zuo)用(yong)和(he)(he)功能(neng)不同(tong)(tong)。伺(si)服(fu)(fu)電(dian)機(ji)(ji)(ji)(ji)是執行(xing)(xing)機(ji)(ji)(ji)(ji)構，指在(zai)伺(si)服(fu)(fu)系統(tong)(tong)中，控(kong)(kong)制(zhi)(zhi)機(ji)(ji)(ji)(ji)械元件運轉的(de)發動(dong)機(ji)(ji)(ji)(ji)，是一種(zhong)補助馬(ma)達間接變速(su)裝置(zhi)。伺(si)服(fu)(fu)電(dian)機(ji)(ji)(ji)(ji)可使控(kong)(kong)制(zhi)(zhi)速(su)度、位置(zhi)精(jing)(jing)度非常(chang)準確，可以將電(dian)壓信號(hao)轉化為轉矩和(he)(he)轉速(su)以驅(qu)動(dong)控(kong)(kong)制(zhi)(zhi)對象(xiang)。伺(si)服(fu)(fu)驅(qu)動(dong)器(qi)(qi)是用(yong)來控(kong)(kong)制(zhi)(zhi)伺(si)服(fu)(fu)電(dian)機(ji)(ji)(ji)(ji)的(de)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)，其作(zuo)用(yong)類似于變頻器(qi)(qi)作(zuo)用(yong)于普通(tong)交流馬(ma)達。伺(si)服(fu)(fu)驅(qu)動(dong)器(qi)(qi)主要用(yong)于高精(jing)(jing)度的(de)定(ding)位系統(tong)(tong)，一般通(tong)過位置(zhi)、速(su)度、力矩三種(zhong)方式對伺(si)服(fu)(fu)電(dian)機(ji)(ji)(ji)(ji)進行(xing)(xing)控(kong)(kong)制(zhi)(zhi)，屬于傳(chuan)動(dong)技術的(de)產(chan)品

伺(si)(si)(si)服(fu)電(dian)(dian)(dian)機(ji)(ji)選(xuan)型(xing)的注意事項1、有些系統(tong)如傳送裝(zhuang)置，升降裝(zhuang)置等(deng)要(yao)(yao)(yao)求(qiu)伺(si)(si)(si)服(fu)電(dian)(dian)(dian)機(ji)(ji)能(neng)盡快停(ting)車，而在故障、急(ji)停(ting)、電(dian)(dian)(dian)源斷電(dian)(dian)(dian)時(shi)(shi)(shi)伺(si)(si)(si)服(fu)器(qi)(qi)沒(mei)有再生制(zhi)(zhi)動(dong)(dong)，無法對(dui)電(dian)(dian)(dian)機(ji)(ji)減速(su)。同時(shi)(shi)(shi)系統(tong)的機(ji)(ji)械(xie)慣(guan)量又較大(da)(da)，這時(shi)(shi)(shi)對(dui)動(dong)(dong)態制(zhi)(zhi)動(dong)(dong)器(qi)(qi)的要(yao)(yao)(yao)依據負載的輕重、電(dian)(dian)(dian)機(ji)(ji)的工作速(su)度等(deng)進行選(xuan)擇。2、有些系統(tong)要(yao)(yao)(yao)維(wei)持機(ji)(ji)械(xie)裝(zhuang)置的靜止(zhi)位置，需(xu)電(dian)(dian)(dian)機(ji)(ji)提供較大(da)(da)的輸出轉(zhuan)矩，且停(ting)止(zhi)的時(shi)(shi)(shi)間較長。如果使用(yong)伺(si)(si)(si)服(fu)的自鎖功能(neng)，往往會造成電(dian)(dian)(dian)機(ji)(ji)過(guo)熱或放大(da)(da)器(qi)(qi)過(guo)載，這種情況(kuang)就要(yao)(yao)(yao)選(xuan)擇帶電(dian)(dian)(dian)磁(ci)制(zhi)(zhi)動(dong)(dong)的電(dian)(dian)(dian)機(ji)(ji)。3、有的伺(si)(si)(si)服(fu)驅動(dong)(dong)器(qi)(qi)有內(nei)置的再生制(zhi)(zhi)動(dong)(dong)單元，但當再生制(zhi)(zhi)動(dong)(dong)較頻(pin)繁時(shi)(shi)(shi)，可(ke)能(neng)引起直流母線電(dian)(dian)(dian)壓過(guo)高，這時(shi)(shi)(shi)需(xu)另配(pei)再生制(zhi)(zhi)動(dong)(dong)電(dian)(dian)(dian)阻。再生制(zhi)(zhi)動(dong)(dong)電(dian)(dian)(dian)阻是否(fou)需(xu)要(yao)(yao)(yao)另配(pei)，配(pei)多大(da)(da)，可(ke)參照相應樣本的使用(yong)說明來配(pei)。4、如果選(xuan)擇了帶電(dian)(dian)(dian)磁(ci)制(zhi)(zhi)動(dong)(dong)器(qi)(qi)的伺(si)(si)(si)服(fu)電(dian)(dian)(dian)機(ji)(ji)，電(dian)(dian)(dian)機(ji)(ji)的轉(zhuan)動(dong)(dong)慣(guan)量會增大(da)(da)，計算轉(zhuan)矩時(shi)(shi)(shi)要(yao)(yao)(yao)進行考慮。

伺服電(dian)機(ji)并不(bu)是必須帶減(jian)(jian)速機(ji)。加(jia)(jia)不(bu)加(jia)(jia)減(jian)(jian)速機(ji)是由客戶使(shi)用的(de)(de)(de)工(gong)況(kuang)所決定的(de)(de)(de)。例如在(zai)重載、高精度(du)、高響應(ying)、高穩定性(xing)等場合(he)，有時需(xu)要使(shi)用減(jian)(jian)速機(ji)來匹(pi)配伺服電(dian)機(ji)的(de)(de)(de)性(xing)能，而在(zai)一(yi)些輕載、低速、中精度(du)等場合(he)，有時會選擇不(bu)帶減(jian)(jian)速機(ji)的(de)(de)(de)伺服電(dian)機(ji)。

需(xu)(xu)要使(shi)用(yong)(yong)減(jian)速(su)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)情況有(you)：有(you)重負荷高精度需(xu)(xu)求(qiu)時(shi)。比如(ru)(ru)航空、衛(wei)星、醫(yi)療、科技、晶圓設(she)(she)備(bei)、機(ji)(ji)(ji)器人等(deng)自動化(hua)設(she)(she)備(bei)領(ling)域中(zhong)。他們所(suo)需(xu)(xu)的(de)(de)(de)(de)(de)扭(niu)(niu)矩(ju)(ju)往往遠超(chao)伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)本身(shen)的(de)(de)(de)(de)(de)扭(niu)(niu)矩(ju)(ju)容量，所(suo)以需(xu)(xu)要減(jian)速(su)機(ji)(ji)(ji)來(lai)提(ti)升伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)的(de)(de)(de)(de)(de)輸出扭(niu)(niu)矩(ju)(ju)。需(xu)(xu)要提(ti)高設(she)(she)備(bei)扭(niu)(niu)矩(ju)(ju)時(shi)。設(she)(she)備(bei)如(ru)(ru)果采用(yong)(yong)直接增大(da)伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)的(de)(de)(de)(de)(de)輸出扭(niu)(niu)矩(ju)(ju)的(de)(de)(de)(de)(de)方(fang)法，就(jiu)必須(xu)用(yong)(yong)昂貴大(da)功率的(de)(de)(de)(de)(de)伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)和大(da)功率的(de)(de)(de)(de)(de)驅動器，成本過大(da)，所(suo)以用(yong)(yong)減(jian)速(su)機(ji)(ji)(ji)更加合適。需(xu)(xu)要提(ti)高設(she)(she)備(bei)使(shi)用(yong)(yong)性(xing)能時(shi)。當設(she)(she)備(bei)負載慣量不(bu)當匹配時(shi)，伺(si)(si)服(fu)(fu)(fu)控制就(jiu)會(hui)不(bu)穩定。所(suo)以對于大(da)的(de)(de)(de)(de)(de)負載慣量，一般用(yong)(yong)減(jian)速(su)機(ji)(ji)(ji)的(de)(de)(de)(de)(de)特性(xing)來(lai)控制更加的(de)(de)(de)(de)(de)適合。通常(chang)伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)會(hui)比較(jiao)小型(xing)，而且通常(chang)是長條(tiao)形或(huo)圓柱(zhu)形，整體看起來(lai)比較(jiao)精致。嘉興英威騰MH860伺(si)(si)服(fu)(fu)(fu)電機(ji)(ji)(ji)抱閘
