1軸承壞了，軸承溫度過高，滾道和滾動體有裂痕和傷痕。
潤滑油不足(zu)，老化或者(zhe)加多了(le)，潤滑油不宜(yi)超過軸(zhou)(zhou)承(cheng)蓋和軸(zhou)(zhou)承(cheng)容積(ji)的七成(cheng)。
潤滑(hua)油里邊有鐵粉等雜(za)質(zhi)，或者(zhe)里邊的油環被卡住了。
沒(mei)有安裝(zhuang)到(dao)位，比如軸承，軸承蓋的止口(kou)沒(mei)有裝(zhuang)配，或者兩(liang)者之間過(guo)緊過(guo)松(song)。同(tong)心度(du)沒(mei)有對(dui)好，存在偏心力引起(qi)損壞。
聯(lian)軸(zhou)器(qi)水平沒(mei)有調(diao)整好，傳動之(zhi)間(jian)的鏈(lian)條或者皮帶太(tai)緊了，軸(zhou)受到(dao)負(fu)載力沖擊(ji)變形等。
軸(zhou)(zhou)承質量不行，軸(zhou)(zhou)承的間隙太小或者太大了。
電機啟停頻率過高(gao)，而剛性又過大，對于一些場合不宜全壓啟動，軟啟動會好點。
2選型安裝使用問題
電(dian)機(ji)和負載(zai)之間水平沒有(you)調(diao)整好，造成負載(zai)和電(dian)機(ji)之間不同心而(er)存(cun)在徑向沖擊力。
電機腳的螺絲沒有固定好，或者固定架子沒有設計好。
沒有考(kao)慮(lv)到(dao)(dao)負載情況來(lai)選(xuan)型，有些負載是頻(pin)繁啟停的，也許計(ji)算起來(lai)只需要1KW的功率，設計(ji)上考(kao)慮(lv)到(dao)(dao)散熱和(he)疲軟問題，可能需要3KW來(lai)使(shi)用。
線路接(jie)(jie)錯了，比如星型的(de)接(jie)(jie)成了三角(jiao)型，而三角(jiao)型的(de)接(jie)(jie)成了星型，這樣都可能引起(qi)電(dian)機內(nei)部過熱(re)。
負載需要一些特殊的制動，電機(ji)并沒有對應(ying)的機(ji)械(xie)或者電子剎車，可能在停車時候來不及能量釋放(fang)。
電機沒有設計一些保(bao)護裝置(zhi)，比如(ru)過(guo)熱(re)，過(guo)載，超溫，缺相等，這(zhe)些都(dou)可能(neng)會在(zai)使用過(guo)程(cheng)中發生的(de)，但是因為保(bao)護不到位，直接會把電機燒了。
接線(xian)錯(cuo)誤，或(huo)者正反顛倒了，或(huo)者線(xian)選(xuan)細了，或(huo)者端(duan)子線(xian)耳(er)沒有壓好造成接觸電(dian)阻過大。
如果使用(yong)了光(guang)電編碼(ma)器(qi)之類的，需(xu)要(yao)考(kao)慮一些(xie)粉塵防(fang)(fang)護，防(fang)(fang)撞擊保護。
驅(qu)動器壞了引起電機這邊(bian)瞬間高壓(ya)或者大(da)電流燒壞。
供電(dian)時候(hou)，沒有考慮(lv)到電(dian)機耐壓問題，比(bi)如220伏的，使用了380伏進去了。
一些步進電機(ji)(ji)和伺服電機(ji)(ji)，不能私下拆(chai)開來(lai)更換軸(zhou)承之類的，否則可能會丟磁或者造成編碼器磁極零位偏移(yi)無法(fa)正(zheng)常(chang)使用(yong)。
3環境問題
一些場合粉塵(chen)比較(jiao)多，如果使用(yong)了(le)有刷(shua)直(zhi)流電機，沒有留(liu)意安裝(zhuang)風機之類的裝(zhuang)置來及(ji)時(shi)疏通粉塵(chen)，導致(zhi)碳(tan)刷(shua)和(he)整流子(zi)短(duan)時(shi)間內磨損(sun)。
高溫場合，比如長(chang)期超過(guo)了50度，而負載又比較重，選型電(dian)機(ji)(ji)時候，沒(mei)有使用(yong)F和H這樣耐高溫的電(dian)機(ji)(ji)，同時又沒(mei)有設計單獨風(feng)冷系統，長(chang)期運行(xing)電(dian)機(ji)(ji)溫度過(guo)高。
環境濕度過(guo)高，沒有在用電(dian)絕(jue)緣方面做細節考(kao)慮，可能造成電(dian)路上漏電(dian)。
震(zhen)動大的負載，要(yao)考慮(lv)共振問題(ti)，在固(gu)定電機時候，螺絲的方(fang)向要(yao)考慮(lv)是否會因為震(zhen)動方(fang)向差異(yi)而松動。
4電機質量問題
線圈繞組的銅絲(si)不合格，或者繞的圈數不夠(gou)，或者存在各相阻值(zhi)不一(yi)樣等問題。
鼠籠(long)導條轉子(zi)材料不過關，使用過程中斷裂(lie)。
電機絕緣不好，工廠供電有時候電網電壓會偏高，電壓稍微波動，引起絕緣擊穿。
一(yi)些永磁(ci)電機，磁(ci)性材(cai)料不(bu)耐(nai)高溫，使用一(yi)段時間(jian)后失磁(ci)。
不(bu)(bu)管什(shen)么情況，使用電機過程中，只要(yao)震(zhen)動大，噪(zao)音(yin)響(xiang)，或者有(you)不(bu)(bu)尋(xun)常的(de)味道，都要(yao)停機仔細檢查，確保(bao)沒有(you)問題(ti)后方可繼續使用。
