無刷直流電機由電(dian)(dian)(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)(ji)主體和驅動(dong)(dong)器(qi)組(zu)成，直流(liu)無(wu)刷(shua)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)工(gong)作原理是(shi)無(wu)刷(shua)直流(liu)電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)定(ding)(ding)子(zi)是(shi)線圈繞組(zu)電(dian)(dian)(dian)(dian)(dian)樞，轉(zhuan)子(zi)是(shi)永(yong)磁體。如(ru)果只給電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)通(tong)以(yi)(yi)固(gu)定(ding)(ding)的(de)(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)，則電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)只能產生不變(bian)的(de)(de)(de)磁場(chang)(chang)，電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)不能轉(zhuan)動(dong)(dong)起來，只有實(shi)時檢測電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)轉(zhuan)子(zi)的(de)(de)(de)位(wei)(wei)置，再根(gen)據轉(zhuan)子(zi)的(de)(de)(de)位(wei)(wei)置給電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)(de)(de)不同(tong)相通(tong)以(yi)(yi)對(dui)應的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)，使定(ding)(ding)子(zi)產生方向均勻變(bian)化的(de)(de)(de)旋轉(zhuan)磁場(chang)(chang)，電(dian)(dian)(dian)(dian)(dian)機(ji)(ji)(ji)才可以(yi)(yi)跟著磁場(chang)(chang)轉(zhuan)動(dong)(dong)起來。

直(zhi)流無刷(shua)電(dian)機搭載減速器(qi)（齒輪箱(xiang)）組裝而成直(zhi)流無刷(shua)減速電(dian)機，廣泛運用在電(dian)子產(chan)品、汽車傳動、智能家居、工業(ye)自動化、機械設(she)備(bei)、機器(qi)人設(she)備(bei)、通訊設(she)備(bei)等智能領域。

直流無刷電機優點

1.無電刷、低干擾

無刷電(dian)(dian)(dian)機去除了電(dian)(dian)(dian)刷，直接的變化就是沒有(you)了有(you)刷電(dian)(dian)(dian)機運轉時產(chan)生(sheng)的電(dian)(dian)(dian)火花，這(zhe)樣就極大減(jian)少了電(dian)(dian)(dian)火花對遙(yao)控無線電(dian)(dian)(dian)設(she)備的干擾。

2.噪音低，運(yun)轉順暢(chang)

無刷(shua)電(dian)機沒有了電(dian)刷(shua)，運轉時(shi)摩擦力大(da)大(da)減小(xiao)，運行順暢，噪音會低許多，這個優(you)點(dian)對于模型運行穩(wen)定性是(shi)一個巨大(da)的支持(chi)。

3.壽命長，低維護成本

少了(le)電(dian)(dian)(dian)刷(shua)，無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)的磨損主(zhu)要是(shi)在軸(zhou)承上了(le)，從機(ji)(ji)械角度看(kan)，無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)幾乎是(shi)一(yi)種免(mian)維(wei)護(hu)的電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)了(le)，必要的時候，只需做一(yi)些除塵(chen)維(wei)護(hu)即可(ke)。上下一(yi)比(bi)較，就知道無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)相對于(yu)有刷(shua)電(dian)(dian)(dian)機(ji)(ji)的優(you)勢在哪里(li)了(le)，但是(shi)萬事都不是(shi)的，有刷(shua)電(dian)(dian)(dian)機(ji)(ji)低(di)速(su)扭力性(xing)能(neng)(neng)優(you)異、轉矩大等性(xing)能(neng)(neng)特點是(shi)無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)不可(ke)替代的，不過(guo)就無(wu)刷(shua)電(dian)(dian)(dian)機(ji)(ji)的使(shi)用(yong)方便性(xing)來看(kan)，隨著無(wu)刷(shua)控制器的成本下降(jiang)趨勢和國內(nei)外無(wu)刷(shua)技(ji)術的發(fa)展與(yu)(yu)市場(chang)競爭，無(wu)刷(shua)動(dong)(dong)力系統正在高速(su)的發(fa)展與(yu)(yu)普及階(jie)段，這也極大促進了(le)模型運動(dong)(dong)的發(fa)展。
