一、通电(dian)后直流电(dian)机(ji)不转有嗡嗡声

1．故障原因①转(zhuan)子绕(rao)组(zu)有(you)断路（一相断线）或(huo)电(dian)(dian)源(yuan)一相失(shi)电(dian)(dian)；②绕(rao)组(zu)引出(chu)线始(shi)末端接(jie)(jie)错或(huo)绕(rao)组(zu)内部接(jie)(jie)反；③电(dian)(dian)源(yuan)回路接(jie)(jie)点松动(dong)(dong)，接(jie)(jie)触电(dian)(dian)阻大；④电(dian)(dian)动(dong)(dong)机负载过(guo)大或(huo)转(zhuan)子卡住(zhu)；⑤电(dian)(dian)源(yuan)电(dian)(dian)压过(guo)低；⑥小(xiao)型(xing)电(dian)(dian)动(dong)(dong)机装配太紧或(huo)轴(zhou)承内油脂过(guo)硬；⑦轴(zhou)承卡住(zhu)。

2．故(gu)障(zhang)排(pai)除①查明断点予以修(xiu)复；②检查绕组极性；判(pan)断绕组末端是(shi)(shi)否正确；③紧固松动的接线(xian)螺丝，用万(wan)用表判(pan)断各接头是(shi)(shi)否假接，予以修(xiu)复；④减(jian)载或查出(chu)并消除机械故(gu)障(zhang)，⑤检查是(shi)(shi)否把规定的面接法(fa)误(wu)接；是(shi)(shi)否由于(yu)电(dian)源导线(xian)过细使(shi)压降过大，予以纠正，⑥重新装配(pei)使(shi)之灵活(huo)；更换(huan)合格(ge)油脂；⑦修(xiu)复轴承。

二(er)、直流电(dian)机通电(dian)后(hou)电(dian)动机不(bu)能转(zhuan)动，但(dan)无(wu)异响，也无(wu)异味(wei)和冒(mao)烟。

1．故障原因①电源未(wei)(wei)通(tong)（至(zhi)少两相未(wei)(wei)通(tong)）；②熔丝熔断（至(zhi)少两相熔断）；③过(guo)流继电器调得过(guo)小；④控制设备(bei)接线(xian)错误。

2．故障(zhang)排除①检查电源(yuan)回路开关，熔(rong)丝、接线盒处是否(fou)有断点(dian)，修复(fu)；②检查熔(rong)丝型号、熔(rong)断原因，换新熔(rong)丝；③调节继(ji)电器(qi)整定值与电动机配合；④改正接线。
