伺服电机检测方法/步骤
通电后西门子电动机不能转动，但无异响，也无异味和冒烟。
故障原因①电源未通(至少两相未通);②熔丝熔断(至少两相熔断);③过流继电器调得过小;④控制设备接线错误。
通电后西门子电动机不转有嗡嗡声
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。
西门子电动机起动困难，额定负载时，电动机转速低于额定转速较多
1.故障原因①电源电压过低;②面接法电机误接;③转子开焊或断裂;④转子局部线圈错接、接反;③修复电机绕组时增加匝数过多;⑤电机过载
电动机空载电流不平衡，三相相差大
1.故障原因①绕组首尾端接错;②电源电压不平衡;③绕组存在匝间短路、线圈反接等故障。

电动机运行时响声不正常有异响
故障原因①轴承磨损或油内有砂粒等异物;②转子铁芯松动;③轴承缺油;④电源电压过高或不平衡。

运行中电动机振动较大
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。
