一、無刷減速電機什么意思

直流無刷減速電機，即無刷(shua)齒(chi)輪(lun)(lun)減速(su)電機(ji)，是在直流無刷(shua)電機(ji)的(de)基礎上(shang)，加上(shang)配套(tao)齒(chi)輪(lun)(lun)減速(su)箱。齒(chi)輪(lun)(lun)減速(su)箱的(de)作(zuo)用是，提(ti)供較(jiao)低的(de)轉速(su)，較(jiao)大的(de)力矩。同(tong)時，齒(chi)輪(lun)(lun)箱不(bu)同(tong)的(de)傳動比可以提(ti)供不(bu)同(tong)的(de)轉速(su)和力矩。這大大提(ti)高了直流無刷(shua)電機(ji)在自動化(hua)行業中的(de)使用率。

直流(liu)無(wu)(wu)刷減(jian)(jian)速(su)電機(ji)(ji)是指減(jian)(jian)速(su)機(ji)(ji)和無(wu)(wu)刷電機(ji)(ji)的(de)集成(cheng)(cheng)(cheng)體(ti)(ti)。這種集成(cheng)(cheng)(cheng)體(ti)(ti)通常也(ye)可稱為無(wu)(wu)刷齒輪馬達或無(wu)(wu)刷齒輪電機(ji)(ji)。通常由專(zhuan)業(ye)的(de)減(jian)(jian)速(su)機(ji)(ji)生(sheng)產廠進行集成(cheng)(cheng)(cheng)組裝好(hao)后成(cheng)(cheng)(cheng)套供貨。使用無(wu)(wu)刷減(jian)(jian)速(su)電機(ji)(ji)的(de)優點是簡化設(she)計、節省空間。

直流無(wu)刷減速電機主要(yao)應用(yong)在汽車部(bu)件、線性(xing)驅動、個人護理、智能廚衛、機器人、精密儀(yi)表儀(yi)器、醫療驅動應用(yong)、智能家居(ju)、工(gong)業設(she)備、消(xiao)費電子(zi)產(chan)品、標準微型(xing)齒輪(lun)箱(xiang)等。

二、無刷減速電機的工作原理

無刷(shua)直(zhi)(zhi)流(liu)減速(su)電(dian)(dian)(dian)機為了實(shi)現直(zhi)(zhi)流(liu)電(dian)(dian)(dian)機的無電(dian)(dian)(dian)刷(shua)換向，一般(ban)將電(dian)(dian)(dian)樞繞組放在定子(zi)(zi)上，把(ba)永(yong)磁磁鋼放在轉子(zi)(zi)上，與(yu)(yu)傳統永(yong)磁直(zhi)(zhi)流(liu)減速(su)電(dian)(dian)(dian)機的結構剛好相(xiang)反。但僅這樣做還(huan)不(bu)夠，沒有電(dian)(dian)(dian)刷(shua)的換流(liu)作用(yong)(yong)(yong)，用(yong)(yong)(yong)一般(ban)直(zhi)(zhi)流(liu)電(dian)(dian)(dian)源給定子(zi)(zi)各繞組供電(dian)(dian)(dian)，只能(neng)(neng)產(chan)生(sheng)(sheng)固定磁場，它(ta)不(bu)能(neng)(neng)與(yu)(yu)運動中(zhong)的轉子(zi)(zi)磁鋼所(suo)產(chan)生(sheng)(sheng)的永(yong)磁磁場相(xiang)互作用(yong)(yong)(yong)，來產(chan)生(sheng)(sheng)持續的單一方向的轉矩(ju)，也就(jiu)無法驅(qu)動轉子(zi)(zi)連續轉動。

無刷(shua)直流(liu)減速(su)(su)電(dian)(dian)(dian)(dian)機(ji)用(yong)位置(zhi)(zhi)檢測器(qi)（有(you)位置(zhi)(zhi)傳(chuan)感器(qi)或無位置(zhi)(zhi)傳(chuan)感器(qi)）、電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)換(huan)(huan)向電(dian)(dian)(dian)(dian)路來取(qu)代有(you)刷(shua)直流(liu)減速(su)(su)電(dian)(dian)(dian)(dian)機(ji)的電(dian)(dian)(dian)(dian)刷(shua)和換(huan)(huan)相(xiang)器(qi)，即用(yong)電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)換(huan)(huan)相(xiang)取(qu)代機(ji)械換(huan)(huan)相(xiang)，由位置(zhi)(zhi)傳(chuan)感器(qi)提供(gong)轉(zhuan)(zhuan)子(zi)(zi)(zi)位置(zhi)(zhi)信號，經控(kong)制器(qi)邏(luo)輯處(chu)理(li)后，控(kong)制電(dian)(dian)(dian)(dian)子(zi)(zi)(zi)換(huan)(huan)相(xiang)電(dian)(dian)(dian)(dian)路換(huan)(huan)相(xiang)，使定子(zi)(zi)(zi)繞組所產生(sheng)(sheng)的電(dian)(dian)(dian)(dian)樞(shu)磁場與轉(zhuan)(zhuan)子(zi)(zi)(zi)磁鋼(gang)產生(sheng)(sheng)的永磁磁場相(xiang)互作用(yong)，產生(sheng)(sheng)持續不(bu)斷(duan)的轉(zhuan)(zhuan)矩，保證(zheng)減速(su)(su)電(dian)(dian)(dian)(dian)機(ji)連(lian)續運轉(zhuan)(zhuan)。

無刷直流減速電機的(de)運行方式因(yin)減(jian)速電(dian)機本體的(de)繞(rao)組型(xing)式不同而各異，多數無刷(shua)直流減(jian)速電(dian)機的(de)定子繞(rao)組是三相繞(rao)組。
