直流電機結構復雜,生產成本高,運行維護較為困難,特別是換向器的使用已逐漸不符合現今低損耗節能等基本的要求,加之交流電機的飛速發展,很多場合交流電機已得到普及;但由于直流電機仍具有良好的調速性能,較大的起動轉矩和過載能力等許多優點,因而在煤礦電力機械中應用仍很廣泛。
　　而直流電機的維護及保養主要集中在電刷、換向器、軸承等元件,同時亦是故障的多發區。合理地對其進行維護是正確運行直流電機、迅速排除運行故障的關鍵。
　　1、 直流電機的維護保養
　　1.1 換向器的維護保養
　　換向器是直流電機中的關鍵部件,也是觀察直流電機故障的主要窗口, 直流電機的故障很多,但常見的也是難處理的是換向故障。換向器工作狀況好壞直接關系直流電機的工作狀況,因此必須加強對換向器的維護保養。

減速箱的安裝方法
　　正確的安裝，使用和維護減速箱，是保證機械設備正常運行的重要環節。 因此，在您安裝減速箱時，請務必嚴格按照下面的安裝使用相關事項，認真地裝配和使用。
　　步：安裝前確認電機和減速箱是否完好無損，并且嚴格檢查電機與減速箱相連接的各部位尺寸是否匹配，這里是電機的定位凸臺、輸入軸與減速箱凹槽等尺寸及配合公差。
　　第二步：旋下減速箱法蘭外側防塵孔上的螺釘，調整夾緊環使其側孔與防塵孔對齊，插入內六角旋緊。之后，取走電機軸鍵。
　　第三步：將電機與減速箱自然連接。連接時必須保證減速箱輸出軸與電機輸入軸同心度一致，且二者外側法蘭平行。如同心度不一致，會導致電機軸折斷或減速機齒輪磨損。
