有刷直流減速電機是(shi)在(zai)有(you)刷(shua)電(dian)機的(de)(de)定(ding)子上(shang)安裝有(you)固定(ding)的(de)(de)主磁(ci)和(he)電(dian)刷(shua)，轉子上(shang)安裝有(you)電(dian)樞繞組和(he)換向(xiang)器。由于電(dian)刷(shua)和(he)換向(xiang)器的(de)(de)存在(zai)，有(you)刷(shua)電(dian)機的(de)(de)結構復雜，可靠性差，故(gu)障多，維護工作量大(da)，壽命(ming)短，換向(xiang)火花易產生電(dian)磁(ci)干擾(rao)；這些(xie)不足大(da)大(da)壓縮了有(you)刷(shua)直流減(jian)速機的(de)(de)應(ying)用范圍(wei)。

??無刷直流減速機是在有刷(shua)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)的基礎上開發和優化而(er)來的。無(wu)刷(shua)直流(liu)(liu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)是一種用電(dian)(dian)(dian)(dian)子換(huan)向的小功率直流(liu)(liu)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)。又稱無(wu)換(huan)向器電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)、無(wu)整(zheng)流(liu)(liu)子直流(liu)(liu)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)。它是用半導體逆(ni)變器取代一般直流(liu)(liu)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)中(zhong)的機(ji)(ji)(ji)(ji)械換(huan)向器，構成沒(mei)有換(huan)向器的直流(liu)(liu)電(dian)(dian)(dian)(dian)動機(ji)(ji)(ji)(ji)。無(wu)刷(shua)直流(liu)(liu)減(jian)(jian)速(su)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)結構簡單、運(yun)行速(su)度、壽命長(chang)、運(yun)行穩定、沒(mei)有火花、電(dian)(dian)(dian)(dian)磁噪聲低等特點；無(wu)刷(shua)直流(liu)(liu)減(jian)(jian)速(su)機(ji)(ji)(ji)(ji)相比較于(yu)有刷(shua)直流(liu)(liu)減(jian)(jian)速(su)機(ji)(ji)(ji)(ji)性能更，用途更廣(guang)。

  通(tong)過上述兩點(dian)的分析(xi)，我(wo)們得出結論，無刷(shua)直(zhi)流(liu)減(jian)速(su)(su)機(ji)(ji)的特點(dian)決定(ding)了應用(yong)范圍，無刷(shua)直(zhi)流(liu)減(jian)速(su)(su)機(ji)(ji)常常應用(yong)在家用(yong)電機(ji)(ji)、個人護(hu)理設(she)備、儀(yi)表儀(yi)器等產品(pin)上；有(you)刷(shua)直(zhi)流(liu)減(jian)速(su)(su)電機(ji)(ji)的缺點(dian)，決定(ding)了應用(yong)范圍狹小，在未來將會(hui)慢(man)慢(man)的被(bei)淘(tao)汰；無刷(shua)直(zhi)流(liu)減(jian)速(su)(su)電機(ji)(ji)的在滿足市場需(xu)求(qiu)(qiu)的同時(shi)，做出更(geng)優化的改進，提供定(ding)制功率模式服(fu)務(wu)，即按(an)照(zhao)需(xu)求(qiu)(qiu)定(ding)制直(zhi)流(liu)減(jian)速(su)(su)電機(ji)(ji)；如有(you)疑問立即聯系兆威機(ji)(ji)電工程(cheng)師(shi)，我(wo)們將會(hui)在時(shi)間為(wei)您解(jie)答！
