精密無刷電機，主要是指無刷直流電機，通用名詞為BLDC。由(you)電(dian)(dian)動機(ji)(ji)(ji)主體和驅(qu)動器(qi)組(zu)成，是(shi)一(yi)種典(dian)型(xing)的(de)機(ji)(ji)(ji)電(dian)(dian)一(yi)體化產品。由(you)于無刷直流電(dian)(dian)動機(ji)(ji)(ji)是(shi)以自控(kong)式運行的(de)，所(suo)以不會像變頻調速下重載(zai)(zai)啟(qi)(qi)動的(de)同步電(dian)(dian)機(ji)(ji)(ji)那樣在轉子上另(ling)加啟(qi)(qi)動繞組(zu)，也不會在負載(zai)(zai)突變時產生振蕩和失步。

精(jing)密無刷直流電機的(de)運轉(zhuan)效(xiao)率、低速轉(zhuan)矩、轉(zhuan)速精(jing)度等都(dou)比其他控制(zhi)技術的(de)變頻器好(hao)，主要(yao)體現在：

1.無電刷、低干擾

無刷電(dian)(dian)機去除(chu)了電(dian)(dian)刷，直接的變化就是沒有了有刷電(dian)(dian)機運轉時(shi)產(chan)生的電(dian)(dian)火花(hua)，這樣就極大減少了電(dian)(dian)火花(hua)對遙控(kong)無線電(dian)(dian)設備的干擾(rao)。

2.噪音低，運轉(zhuan)順暢

無刷電機(ji)沒有(you)了(le)電刷，運(yun)轉時摩擦力大大減小，運(yun)行順暢，噪音會低許多，這個優點對于模型運(yun)行穩定性(xing)是(shi)一個巨大的支持。

3.壽命長(chang)，低維(wei)護成本

少了電(dian)(dian)(dian)(dian)刷(shua)(shua)(shua)，無刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)磨損主要是(shi)在軸承上(shang)了，從機(ji)(ji)械角度看，無刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)幾乎是(shi)一(yi)種免(mian)維(wei)護的(de)(de)(de)電(dian)(dian)(dian)(dian)動機(ji)(ji)了，必要的(de)(de)(de)時候(hou)，只需(xu)做一(yi)些除塵維(wei)護即可。上(shang)下一(yi)比較，就知道無刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)相(xiang)對于有刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)優(you)勢在哪(na)里了，但是(shi)萬(wan)事(shi)都不是(shi)的(de)(de)(de)，有刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)低速(su)(su)扭力(li)性(xing)能(neng)優(you)異、轉矩(ju)大等性(xing)能(neng)特點是(shi)無刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)不可替(ti)代的(de)(de)(de)，不過就無刷(shua)(shua)(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)使用(yong)方便性(xing)來看，隨著無刷(shua)(shua)(shua)控制器的(de)(de)(de)成本下降趨勢和國內外無刷(shua)(shua)(shua)技術(shu)的(de)(de)(de)發(fa)展(zhan)與(yu)市(shi)場競爭，無刷(shua)(shua)(shua)動力(li)系統正在高速(su)(su)的(de)(de)(de)發(fa)展(zhan)與(yu)普及階段，這也(ye)極大促(cu)進了模型(xing)運動的(de)(de)(de)發(fa)展(zhan)。
