描述
6ES5421-8MA12
与电机相联的齿轮、联轴器有毛病。这种故障主要表现为齿轮咬合不良，轮齿磨损严重，对轮润滑不良，联轴器歪斜、错位，齿式联轴器齿形、齿距不对、间隙过大或磨损严重，都会造成一定的振动。
电机本身结构的缺陷和安装的问题。这种故障主要表现为轴颈椭圆，转轴弯曲，轴与轴瓦间间隙过大或过小，轴承座、基础板、地基的某部分乃至整个电机安装基础的刚度不够，电机与基础板之间固定不牢，底脚螺栓松动，轴承座与基础板之间松动等。而轴与轴瓦间间隙过大或过小不仅可以造成振动还可使轴瓦的润滑和温度产生异常。电枢不平衡。由于旋转时不平衡质量产生的离心力的作用，使轴承上作用有一个旋转力，造成了电机和基础的振动。当气隙不匀、主极固定不紧或机座、端盖的刚度较差时，都会造成振动加剧，因此检查发现转子不平衡时，必须重新进行动平衡。
