驅動器的電(dian)源(yuan)應(ying)該怎么(me)去選擇

一臺(tai)步進(jin)驅動器要配(pei)上合(he)適的(de)電(dian)源才可以(yi)發(fa)揮(hui)它的(de)性能到(dao)(dao)較(jiao)大(da)，那(nei)電(dian)源到(dao)(dao)底應該(gai)怎么去選擇(ze)呢。

1.首先電源的電壓值比例是較大電壓的15%-55%左(zuo)右，百分比ke.kt所以電壓隨即(ji)就下(xia)降了但(dan)是都是不一樣

2.步(bu)進(jin)驅動器的電流值必(bi)須要足以(yi)傳遞所需(xu)的能量(liang)

3.在這個地(di)方一(yi)點要切(qie)記步(bu)進(jin)驅動(dong)器輸(shu)出電(dian)壓(ya)值和供電(dian)電(dian)壓(ya)是不一(yi)樣的，總線型步(bu)進(jin)驅動(dong)器公司，所以步(bu)進(jin)驅動(dong)器輸(shu)入電(dian)流和輸(shu)入電(dian)流也是不相同的。

4.要是想提供合適的(de)(de)供電(dian)電(dian)流(liu)就(jiu)必(bi)須要去(qu)計算在原有(you)的(de)(de)需求基礎(chu)上增加6%，按(an)照下面公司來計算i=p/u就(jiu)可(ke)以算出來我們需要的(de)(de)電(dian)流(liu)。

5.如果(guo)我們單單從步進電機的角度去(qu)說的話，電源的功率越(yue)大越(yue)好，但(dan)是(shi)我們在日常生活(huo)中的要求就不一樣我們的要求是(shi)越(yue)低越(yue)好以為往往要去(qu)節約成(cheng)本。

6.但是(shi)(shi)一(yi)旦功(gong)率(lv)過低的話就很容(rong)易導致步(bu)進(jin)電機在需(xu)要(yao)(yao)動力的時候可(ke)能出(chu)現不足以(yi)及(ji)丟步(bu)的現象(xiang)產生，在有就是(shi)(shi)容(rong)易損害步(bu)進(jin)驅(qu)動器以(yi)及(ji)開關電源，這(zhe)個沒有一(yi)個統一(yi)的標準大家(jia)根據廠(chang)家(jia)的要(yao)(yao)求以(yi)及(ji)產品的配置去(qu)靈活運(yun)用。
