直流永磁電機型號優點

1.高效節能。因勵磁磁場由永磁體提供，永磁轉子不需要勵磁，效率可高達90%以上。與異步電機相比，高效率運行轉速范圍寬，節能顯著。尤其在低轉速運行時，優勢更加明顯。
2.溫升低。無電勵磁意味著無損耗發熱，因此，永磁電機一般溫升很低。
3.起動性能好。自啟動永磁同步電機一般也采用異步起動方式。正常工作時永磁同步電機轉子繞組不起作用，可將永磁電機轉子繞組設計為*高起動轉矩的要求，如起動轉矩倍數由1.8倍提升到2.5倍或更大。
4.對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)運(yun)行(xing)的影響。異(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機要從(cong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)中吸收大量(liang)的無功電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)輸變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統有大量(liang)無功電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，進而使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)的品質因數下降，加(jia)(jia)重輸變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備及(ji)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備的負荷。同時，無功電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)即輸變(bian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統中均要消耗部分電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)，造成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)運(yun)行(xing)效(xiao)率低下，再與(yu)異(yi)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機效(xiao)率低、從(cong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)多吸收電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)的情況疊加(jia)(jia)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)量(liang)損(sun)失(shi)加(jia)(jia)劇，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)負荷愈(yu)發(fa)加(jia)(jia)重了。

選用原則

（1）類(lei)型的選擇(ze)

宜優先選用(yong)效率高、價格便宜、溫升(sheng)低的(de)鐵(tie)氧體永(yong)磁直流(liu)電動(dong)機。只(zhi)有當對性能要求嚴格、體積小、環境溫度(du)較高時(shi)才考慮選用(yong)鋁鎳(nie)鈷永(yong)磁直流(liu)電動(dong)機或(huo)稀土永(yong)磁直流(liu)電動(dong)機。

（2）合理選擇電動機的功率

電動(dong)(dong)(dong)機(ji)(ji)輸(shu)出(chu)的(de)最大功(gong)(gong)率(lv)是有限度的(de)，如(ru)果電動(dong)(dong)(dong)機(ji)(ji)的(de)功(gong)(gong)率(lv)選擇(ze)過小，負載超過了電動(dong)(dong)(dong)機(ji)(ji)的(de)額定(ding)輸(shu)出(chu)功(gong)(gong)率(lv)就(jiu)會(hui)發生(sheng)電動(dong)(dong)(dong)機(ji)(ji)過載，過載時會(hui)出(chu)現電動(dong)(dong)(dong)機(ji)(ji)發熱、振動(dong)(dong)(dong)、轉速(su)下降、聲音異常等(deng)現象(xiang)，嚴重(zhong)過載時，將會(hui)燒毀電動(dong)(dong)(dong)機(ji)(ji)。而(er)功(gong)(gong)率(lv)過大，則會(hui)造成經濟浪費(fei)。因此合理選擇(ze)電動(dong)(dong)(dong)機(ji)(ji)的(de)功(gong)(gong)率(lv)是很重(zhong)要的(de)。

（3）規格(ge)選擇

往往由于(yu)實(shi)際生產(chan)(chan)的(de)產(chan)(chan)品規(gui)格(ge)(ge)不多，給選(xuan)(xuan)用(yong)產(chan)(chan)品增加困難(nan)。在(zai)選(xuan)(xuan)擇產(chan)(chan)品規(gui)格(ge)(ge)時(shi)可(ke)(ke)(ke)考慮：在(zai)電源電壓(ya)可(ke)(ke)(ke)調的(de)場合，可(ke)(ke)(ke)按實(shi)際需要選(xuan)(xuan)擇轉(zhuan)矩、轉(zhuan)速(su)與產(chan)(chan)品相應的(de)額定(ding)值接近的(de)規(gui)格(ge)(ge)，通過改變電壓(ya)得到所(suo)需轉(zhuan)速(su)；在(zai)電源電壓(ya)固定(ding)的(de)場合，如(ru)果沒有適當規(gui)格(ge)(ge)的(de)產(chan)(chan)品可(ke)(ke)(ke)供(gong)選(xuan)(xuan)用(yong)時(shi)，可(ke)(ke)(ke)先按轉(zhuan)矩選(xuan)(xuan)擇適當規(gui)格(ge)(ge)，而產(chan)(chan)品的(de)電壓(ya)與轉(zhuan)速(su)之間(jian)可(ke)(ke)(ke)作適當調整。

二、永(yong)磁無刷直流電動機在應(ying)用時應(ying)注意：

（1）如果(guo)產品(pin)沒有(you)特(te)別說(shuo)明，一般情況(kuang)下（例如鋁鎳(nie)鈷永磁(ci)直(zhi)流(liu)電動機(ji)或鐵氧(yang)體(ti)永磁(ci)直(zhi)流(liu)電動機(ji)）永磁(ci)直(zhi)流(liu)電動機(ji)都不(bu)允許在額(e)定電壓下反接制(zhi)動運行，否則會(hui)造成永磁(ci)體(ti)退磁(ci)；如確有(you)必要(yao)作這種方式運行時(shi)，要(yao)加限(xian)流(liu)電阻，以限(xian)制(zhi)電流(liu)過大。

（2）按以下步(bu)驟對電機好(hao)壞(huai)進(jin)行初步(bu)的檢查：

首(shou)先(xian)檢(jian)查電(dian)(dian)機(ji)(ji)的(de)(de)外觀：應(ying)無劃痕、碰傷和涂鍍層(ceng)脫落；然后(hou)轉(zhuan)(zhuan)動轉(zhuan)(zhuan)軸，應(ying)能靈活轉(zhuan)(zhuan)動，無明顯的(de)(de)卡殼現象。檢(jian)查電(dian)(dian)動機(ji)(ji)的(de)(de)接線是否牢固(gu)，并通電(dian)(dian)運行(xing)。電(dian)(dian)動機(ji)(ji)在旋(xuan)轉(zhuan)(zhuan)的(de)(de)過程(cheng)中應(ying)不存在著摩擦，其(qi)中較突出(chu)的是軸承摩擦(ca)。軸承磨損后(hou)會(hui)發出不正常聲(sheng)音，出現(xian)局部過(guo)熱溫升現(xian)象。

（3）注意電(dian)動機(ji)因(yin)電(dian)流過大、溫度變(bian)化及拆裝時(shi)磁(ci)(ci)路開(kai)路而(er)引(yin)起的永(yong)磁(ci)(ci)體退磁(ci)(ci)，尤其對(dui)于鋁鎳鈷(gu)永(yong)磁(ci)(ci)電(dian)動機(ji)，拆裝時(shi)要對(dui)永(yong)磁(ci)(ci)磁(ci)(ci)路進行磁(ci)(ci)短路保護，否則退磁(ci)(ci)后要另外充磁(ci)(ci)。
