微型直流無刷電機控(kong)制(zhi)設備(bei)是用來控(kong)制(zhi)電(dian)(dian)機(ji)的(de)運(yun)轉，有各種控(kong)制(zhi)電(dian)(dian)動(dong)(dong)機(ji)，電(dian)(dian)器，自動(dong)(dong)化元件(jian)及工業控(kong)制(zhi)計算機(ji)組成(cheng)。電(dian)(dian)動(dong)(dong)機(ji)是生產機(ji)械(xie)的(de)原動(dong)(dong)機(ji)，將(jiang)電(dian)(dian)能(neng)轉化成(cheng)機(ji)械(xie)能(neng)。

微型直流(liu)(liu)無刷電(dian)(dian)(dian)(dian)機(ji)斬(zhan)波(bo)(bo)調(diao)速原理是利用可(ke)控硅整流(liu)(liu)調(diao)壓(ya)來達直流(liu)(liu)電(dian)(dian)(dian)(dian)機(ji)調(diao)速的目(mu)的，利用交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)相位延遲(chi)一(yi)定時間發(fa)出觸發(fa)信號使可(ke)控硅導通(tong)即為(wei)斬(zhan)波(bo)(bo)，斬(zhan)波(bo)(bo)后(hou)的交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)經(jing)電(dian)(dian)(dian)(dian)機(ji)濾波(bo)(bo)后(hou)其平均電(dian)(dian)(dian)(dian)壓(ya)隨斬(zhan)波(bo)(bo)相位變(bian)化(hua)而變(bian)化(hua)。為(wei)了(le)達到控制直流(liu)(liu)電(dian)(dian)(dian)(dian)機(ji)目(mu)的，在控制回路(lu)加入了(le)速度、電(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)流(liu)(liu)反饋環路(lu)和PID調(diao)節(jie)器來防止(zhi)電(dian)(dian)(dian)(dian)機(ji)由于負(fu)載變(bian)化(hua)而引起的波(bo)(bo)動和對電(dian)(dian)(dian)(dian)機(ji)速度、電(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)流(liu)(liu)超常(chang)保護。

微型(xing)直(zhi)流無刷電機具有(you)呼應疾速(su)、較大(da)的起動轉矩、從(cong)零轉速(su)至額(e)(e)外轉速(su)具有(you)可提供(gong)額(e)(e)外轉矩的功(gong)能，但微型(xing)直(zhi)流電機的特點(dian)也正是它(ta)的缺陷(xian)，因此，微型(xing)直(zhi)流電機要發生額(e)(e)外負載下恒定轉矩的功(gong)能，進(jin)行(xing)斬波調速(su)。

上面是兆威機電通(tong)過(guo)多(duo)年積累的(de)(de)經驗(yan)總結出的(de)(de)微型(xing)直流無刷電機斬波的(de)(de)調速原理(li)。你(ni)們(men)看懂(dong)了嗎？如有不懂(dong)的(de)(de)地方，歡迎來電咨詢！
