其(qi)中，直(zhi)(zhi)流力(li)矩電(dian)(dian)機的自感(gan)電(dian)(dian)抗(kang)很小，所以響應(ying)性很好;其(qi)輸(shu)(shu)出力(li)矩與輸(shu)(shu)入電(dian)(dian)流成(cheng)正(zheng)比，與轉子的速(su)(su)度和位置無關;它可(ke)以在(zai)接近(jin)堵轉狀(zhuang)態下直(zhi)(zhi)接和負載連接低(di)速(su)(su)運行而(er)不用齒(chi)輪減速(su)(su)，所以在(zai)負載的軸上能(neng)產(chan)生很高的力(li)矩對(dui)慣性比，并能(neng)消除由于使用減速(su)(su)齒(chi)輪而(er)產(chan)生的系統誤差(cha)。

良好的粘溫特性

各種潤滑油的(de)粘度隨溫(wen)(wen)(wen)(wen)度升高(gao)而(er)降低(di)，下降的(de)比例越小，則其粘溫(wen)(wen)(wen)(wen)性(xing)能(neng)越好(hao)。特別是(shi)汽車(che)及工程機(ji)械齒(chi)輪(lun)油工作溫(wen)(wen)(wen)(wen)度變化(hua)范圍(wei)很大，因此(ci)，希望(wang)齒(chi)輪(lun)油的(de)粘度隨溫(wen)(wen)(wen)(wen)度的(de)變化(hua)越小越好(hao)。如齒(chi)輪(lun)油的(de)粘溫(wen)(wen)(wen)(wen)特性(xing)不好(hao)，則啟(qi)動(dong)時粘度太大，不易啟(qi)動(dong)，而(er)運(yun)轉達到溫(wen)(wen)(wen)(wen)度高(gao)粘度又太小。

齒輪(lun)油的(de)(de)粘(zhan)(zhan)度(du)也是重要(yao)的(de)(de)使(shi)用性能之一，粘(zhan)(zhan)度(du)對油膜的(de)(de)形成影響很大。一般(ban)而言，高粘(zhan)(zhan)度(du)齒輪(lun)油可(ke)有(you)效(xiao)防止(zhi)齒輪(lun)及(ji)(ji)軸承損(sun)傷，可(ke)減少機械運轉(zhuan)(zhuan)噪聲及(ji)(ji)減少漏油；低粘(zhan)(zhan)度(du)油在提(ti)高機械運轉(zhuan)(zhuan)效(xiao)率加(jia)強冷卻及(ji)(ji)清洗作(zuo)用和油的(de)(de)傳送(song)方面具有(you)優點(dian)。

為了(le)(le)(le)減(jian)少燃料消耗，國外推行了(le)(le)(le)發動機油(you)(you)、齒(chi)輪(lun)油(you)(you)的(de)低粘(zhan)度(du)化。低粘(zhan)度(du)齒(chi)輪(lun)油(you)(you)的(de)優點是(shi)齒(chi)輪(lun)齒(chi)的(de)攪拌阻力小，并且有較好的(de)低溫流(liu)動性(xing)(xing)，在(zai)低溫條(tiao)件下能確(que)保潤滑。近年來(lai)國內也生產了(le)(le)(le)一些(xie)低粘(zhan)度(du)的(de)齒(chi)輪(lun)油(you)(you)，為了(le)(le)(le)改普其(qi)潤滑性(xing)(xing)能而加(jia)入了(le)(le)(le)一些(xie)多效添加(jia)劑，這對(dui)減(jian)少動力損失是(shi)十(shi)分有利的(de)。當然，在(zai)其(qi)體(ti)使用時，要加(jia)強對(dui)齒(chi)輪(lun)箱體(ti)的(de)密封，以防止齒(chi)輪(lun)油(you)(you)漏損。

這里(li)所(suo)說(shuo)的“加大變頻(pin)器容量”，是相對于變頻(pin)器的配用電(dian)動機容量等于實際電(dian)動機容量而言的。大體上說(shuo)，可歸納如下：

01

變(bian)(bian)頻(pin)器的(de)(de)額定(ding)電(dian)流偏低 如上述(shu)，部分(fen)變(bian)(bian)頻(pin)器的(de)(de)額定(ding)電(dian)流小(xiao)于同容量電(dian)動(dong)機(ji)(ji)的(de)(de)額定(ding)電(dian)流時(shi)，應(ying)(ying)根據電(dian)動(dong)機(ji)(ji)的(de)(de)負載(zai)情況考慮選擇大(da)一擋的(de)(de)變(bian)(bian)頻(pin)器02 電(dian)動(dong)機(ji)(ji)可能短時(shi)間(jian)過(guo)(guo)載(zai)者 因為電(dian)動(dong)機(ji)(ji)所謂(wei)的(de)(de)“短時(shi)間(jian)”，是(shi)相對(dui)于發(fa)熱時(shi)間(jian)常數而(er)言的(de)(de)。少則(ze)(ze)幾(ji)分(fen)鐘，多(duo)則(ze)(ze)幾(ji)十分(fen)鐘。而(er)變(bian)(bian)頻(pin)器的(de)(de)過(guo)(guo)載(zai)能力，通常是(shi)150%，1min。與電(dian)動(dong)機(ji)(ji)相比，等于沒有過(guo)(guo)載(zai)能力。所以，如果電(dian)動(dong)機(ji)(ji)可能在智囊時(shi)間(jian)內過(guo)(guo)載(zai)運行的(de)(de)話，變(bian)(bian)頻(pin)器的(de)(de)容量應(ying)(ying)加大(da)。
