通電后機床不轉有嗡(weng)嗡(weng)聲

l．故(gu)障原因①定、轉子(zi)繞組(zu)有(you)斷(duan)路（一(yi)相(xiang)斷(duan)線(xian)）或電(dian)(dian)源(yuan)(yuan)一(yi)相(xiang)失電(dian)(dian)；②繞組(zu)引出(chu)線(xian)始末端(duan)接錯或繞組(zu)內(nei)部接反(fan)；③電(dian)(dian)源(yuan)(yuan)回路接點松動(dong)(dong)(dong)，接觸電(dian)(dian)阻大(da)；④電(dian)(dian)動(dong)(dong)(dong)機(ji)負載過大(da)或轉子(zi)卡住；⑤電(dian)(dian)源(yuan)(yuan)電(dian)(dian)壓過低(di)；⑥小型電(dian)(dian)動(dong)(dong)(dong)機(ji)裝配太(tai)緊(jin)或軸承(cheng)(cheng)內(nei)油脂過硬(ying)；⑦軸承(cheng)(cheng)卡住。

2．故障(zhang)排除(chu)①查明斷(duan)點予以修復(fu)；②檢(jian)(jian)查繞(rao)組極性；判(pan)斷(duan)繞(rao)組末(mo)端是(shi)否(fou)(fou)正確；③緊固松動的(de)接(jie)線螺絲(si)，用萬用表判(pan)斷(duan)各(ge)接(jie)頭是(shi)否(fou)(fou)假(jia)接(jie)，予以修復(fu)；④減(jian)載或查出(chu)并消除(chu)機械(xie)故障(zhang)，⑤檢(jian)(jian)查是(shi)還把規定的(de)面接(jie)法誤接(jie)為Y；是(shi)否(fou)(fou)由于(yu)電源導線過(guo)細(xi)使(shi)壓降過(guo)大，予以糾正，機床數(shu)控改造廠家，⑥重新裝配使(shi)之(zhi)靈活(huo)；更換合格油脂(zhi)；⑦修復(fu)軸(zhou)承(cheng)。
