多速(su)電(dian)(dian)(dian)(dian)機(ji)分(fen)為(wei)兩(liang)(liang)個(ge)主要組(zu)，分(fen)為(wei)“兩(liang)(liang)個(ge)獨立(li)的(de)(de)繞組(zu)”或“Dahlander繞組(zu)”。在(zai)兩(liang)(liang)個(ge)單獨的(de)(de)繞組(zu)電(dian)(dian)(dian)(dian)機(ji)中，通(tong)過帶(dai)有定子的(de)(de)兩(liang)(liang)個(ge)獨立(li)繞組(zu)獲得(de)所需(xu)的(de)(de)速(su)度。在(zai)Dahlander繞組(zu)電(dian)(dian)(dian)(dian)機(ji)中，通(tong)常從單卷繞電(dian)(dian)(dian)(dian)機(ji)獲得(de)兩(liang)(liang)種(zhong)不(bu)(bu)(bu)同(tong)速(su)度的(de)(de)2：1比率。TEE使(shi)(shi)用(yong)(yong)(yong)閉式(shi)（2Z）滾(gun)子軸(zhou)承。這些類型(xing)的(de)(de)滾(gun)子軸(zhou)承不(bu)(bu)(bu)需(xu)要維護，因為(wei)它們是用(yong)(yong)(yong)制(zhi)造商規定的(de)(de)潤(run)滑(hua)劑潤(run)滑(hua)的(de)(de)。由于(yu)指定的(de)(de)工作溫度，振動水平和(he)軸(zhou)負(fu)載，應在(zai)運行20,000小時后（約2-5年使(shi)(shi)用(yong)(yong)(yong)）更換滾(gun)子軸(zhou)承。軸(zhou)承潤(run)滑(hua)通(tong)道和(he)電(dian)(dian)(dian)(dian)機(ji)的(de)(de)油嘴有外部潤(run)滑(hua)軸(zhou)承。潤(run)滑(hua)后，必(bi)(bi)須(xu)關閉油嘴蓋。在(zai)潤(run)滑(hua)過程中，必(bi)(bi)須(xu)避免(mian)油污(wu)和(he)灰塵。應考慮潤(run)滑(hua)脂數量，不(bu)(bu)(bu)得(de)使(shi)(shi)用(yong)(yong)(yong)不(bu)(bu)(bu)同(tong)的(de)(de)潤(run)滑(hua)脂。必(bi)(bi)須(xu)避免(mian)使(shi)(shi)用(yong)(yong)(yong)不(bu)(bu)(bu)同(tong)潤(run)滑(hua)脂的(de)(de)混合物。在(zai)基本(ben)設計(ji)中，電(dian)(dian)(dian)(dian)機(ji)不(bu)(bu)(bu)加(jia)孔。在(zai)客戶要求的(de)(de)情況下，電(dian)(dian)(dian)(dian)機(ji)可提(ti)供排(pai)水孔。由于(yu)這些電(dian)(dian)(dian)(dian)機(ji)在(zai)孔中設有專(zhuan)用(yong)(yong)(yong)插頭，所以防護等級為(wei)IP55。
