西(xi)門子6RA70直流調速(su)器(qi)維(wei)修方法(fa)如下：

1、檢(jian)查電樞碳刷，碳刷的長度，接觸(chu)面和彈力都合(he)適；

3、檢查測(ce)(ce)速反饋部(bu)件(jian)與(yu)電機非負載測(ce)(ce)的連軸節(jie)沒有問(wen)題。

4、檢查馬(ma)達(da)波箱是否有問題，漏油(you)、潤滑(hua)不良，傳動機構磨損(sun)，可能(neng)造成(cheng)負荷不平(ping)穩而(er)使調(diao)(diao)速器頻繁調(diao)(diao)節。

如果是模擬調速系統，對于(yu)一般的電氣維修人(ren)員(yuan)難度會比較(jiao)大，但(dan)仍(reng)然要(yao)按(an)以下步驟處理：
