故障排除

①检查电源回路开关，熔丝、接线盒处是否有断点，修复；

②检查熔丝型号、熔断原因，换新熔丝；

③调节继电器整定值与电动机配合；

④改正接线。

运行中电动机振动较大   1、故障原因

①由于磨损轴承间隙过大；

②气隙不均匀；

③转子不平衡；

④转轴弯曲；

⑤联轴器（皮带轮）同轴度过低。

2、故障排除

①检修轴承，必要时更换；

②调整气隙，使之均匀；

③校正转子动平衡；

④校直转轴；

⑤重新校正，使之符合规定。

通电后电机不转有嗡嗡声   1、故障原因

①转子绕组有断路（一相断线）或电源一相失电；

②绕组引出线始末端接错或绕组内部接反；

③电源回路接点松动，接触电阻大；

④电动机负载过大或转子卡住；

⑤电源电压过低；

⑥小型电动机装配太紧或轴承内油脂过硬；

⑦轴承卡住。
