笼型电机修理时未装两端盖之前，绕组对机壳绝缘良好。装上后，绝缘电阻降低。这种现象可判断故障发生在绕组的两端部。造成绝缘电阻降低的原因，可能是漆包线上漆膜有局部碰破或绕线模偏大使绕组端部伸出较长。因端盖罩上后，端盖内壁靠近或接触故障点，所以使绕组绝缘电阻降低。要排除这种故障，首先应判断故障在电机哪一端。

判断方法是：先装一头端盖，用500V绝缘电阻表测绕组的绝缘电阻，如很低，则说明这端绕组有故障存在。然后，拆下这头端盖，再装上另一头端盖，测量绕组的绝缘电阻，如也低，则说明另一端也有故障存在。在拆、装端盖的过程中，转子可不装。确定故障端后，一般对绕组端部稍微整形一下，并涂些绝缘漆即可，如未解决问题，则可在绕组端部外侧容易与端盖内侧接触处垫上一层薄膜青壳纸，故障一般可消除。

寻找接地点的方法有如下几点：

仔细检查引出线和槽子两端，发现引出线完好，槽子两端槽口绝缘均无损坏，电机内外很干净，各处无灰尘及油污，这说明接地点在槽内。

解开定子绕组的Y型连接点，分别测量各相对地绝缘电阻，查出有接地故障的相。

用一台单相调压器，其输出端的相线接到有接地故障相的一端引出线上，零线接电机机壳，然后将调压器从零开始升压，至槽内冒烟，这是立即将调压器输出电压将为零并切断电源，冒烟处就是接地点。整个操作过程都要注意安全，要将电机放在一块绝缘垫上，切断电源前人身不能接触电机。处理方法是：把有接地槽的槽楔小心去除，然后将电机放入烘箱内加热，烘软绕组，然后仔细将槽内线匝取出，检查各导线绝缘。绝缘被破坏的要涂漆、烘干，然后重新在槽内放置槽绝缘纸，再将所取出的线匝放入槽内，打入槽楔，绕组浸漆、烘干。如发现漆包线已被烧断，要将两根断线头分别拉到绕组的端部，然后找一根线径相同的漆包线放入槽内，在绕组两端部接线。接头要绞合锡焊、涂漆、烘干，再套上绝缘套管。捆扎端部时，要注意捆扎接头。
