直流無(wu)刷控(kong)制器(qi)和直流無(wu)刷電機(ji)怎樣能倒出正確的相序？

答：步(bu)要保(bao)證(zheng)霍(huo)(huo)(huo)爾(er)線(xian)(xian)的(de)電源(yuan)線(xian)(xian)和地線(xian)(xian)與(yu)控(kong)制(zhi)(zhi)器(qi)上(shang)相對(dui)應的(de)線(xian)(xian)插好，而三個電機霍(huo)(huo)(huo)爾(er)線(xian)(xian)與(yu)三個電機線(xian)(xian)對(dui)控(kong)制(zhi)(zhi)器(qi)的(de)接(jie)(jie)法共(gong)有 36 種，簡單而笨的(de)方法是每種狀(zhuang)態(tai)逐一(yi)(yi)試(shi)驗。換接(jie)(jie)時可以不(bu)斷電進行(xing)，但一(yi)(yi)定要仔細，也要有一(yi)(yi)定的(de)次序(xu)。要注意每次擰轉(zhuan)不(bu)要太(tai)大(da)，如(ru)果電機轉(zhuan)動(dong)不(bu)順利，則這種狀(zhuang)態(tai)就(jiu)是不(bu)對(dui)的(de)，轉(zhuan)把擰的(de)太(tai)大(da)就(jiu)有損控(kong)制(zhi)(zhi)器(qi)，如(ru)果出現反轉(zhuan)的(de)情況，在知道控(kong)制(zhi)(zhi)器(qi)的(de)相序(xu)的(de)情況下(xia)就(jiu)是把控(kong)制(zhi)(zhi)器(qi)霍(huo)(huo)(huo)爾(er)線(xian)(xian) a 、 c 互換，點擊線(xian)(xian) A 相與(yu) B 相互換，即可倒為正轉(zhuan)。后驗證(zheng)接(jie)(jie)得正確(que)方法是大(da)電流運轉(zhuan)時正常。

步進電(dian)動(dong)(dong)機主要(yao)應用在(zai)數控(kong)機床制造領(ling)域，由于步進電(dian)動(dong)(dong)機不需要(yao)A/D轉換，能夠直(zhi)接將數字脈沖信(xin)號轉化成為角位移，所以一直(zhi)被認(ren)為是(shi)理(li)想的數控(kong)機床執行元(yuan)件(jian)。除(chu)了在(zai)數控(kong)機床上的應用，步進電(dian)機也可以用在(zai)其(qi)他(ta)的機械上，比(bi)如作(zuo)為自動(dong)(dong)送料(liao)機中的馬(ma)達，作(zuo)為通用的軟盤驅(qu)動(dong)(dong)器的馬(ma)達，也可以應用在(zai)打(da)印機和繪圖儀(yi)中。
