繞組引出(chu)線標志：

Y系列電機*相(xiang)、第二相(xiang)、第三相(xiang)的(de)首端分別為U1、V1、W1；尾(wei)端分別為U2、V2、W2。

JO2老系列電機*相(xiang)、第(di)二相(xiang)、第(di)三相(xiang)的首端分(fen)別為Dl、D2、D3；尾端分(fen)別為D4、D5、D6。

有(you)些電機，繞組(zu)內部連接好了(le)，只引(yin)(yin)出(chu)三根線，那它們的標志：在(zai)新系列(lie)電機為(wei)U、V、W，在(zai)老系列(lie)電機為(wei)D1、D2、D3。要是(shi)有(you)第四根標志為(wei)N的引(yin)(yin)出(chu)線，這是(shi)星接繞組(zu)的中性點。

工(gong)作原理：

目前，傳統的(de)(de)推(tui)力(li)軸(zhou)承(cheng)一般采(cai)用扇(shan)形(xing)(xing)(xing)(xing)推(tui)力(li)瓦(wa)。該(gai)型(xing)軸(zhou)瓦(wa)適用范圍較廣(guang)，我國現運(yun)行的(de)(de)大(da)多(duo)立式水泵推(tui)力(li)軸(zhou)承(cheng)均采(cai)用該(gai)形(xing)(xing)(xing)(xing)狀(zhuang)推(tui)力(li)瓦(wa)：另外(wai)，水電(dian)行業(ye)的(de)(de)大(da)中型(xing)或(huo)超(chao)大(da)型(xing)發電(dian)機組(zu)體積和(he)重量(liang)都很巨大(da)，在滿足(zu)瓦(wa)面(mian)單位(wei)壓力(li)要(yao)求的(de)(de)前提下，推(tui)力(li)瓦(wa)均為面(mian)積巨大(da)且(qie)形(xing)(xing)(xing)(xing)狀(zhuang)狹長的(de)(de)扇(shan)面(mian)形(xing)(xing)(xing)(xing)，瓦(wa)塊數目眾多(duo)。但是，傳統的(de)(de)扇(shan)形(xing)(xing)(xing)(xing)推(tui)力(li)瓦(wa)面(mian)積越大(da)，變形(xing)(xing)(xing)(xing)越難(nan)以控(kong)制，運(yun)行溫度(du)也可能越高(gao)，實際運(yun)行中，其(qi)變形(xing)(xing)(xing)(xing)量(liang)難(nan)以控(kong)制在良好的(de)(de)范圍內。
