三相鼠笼式异步电动机是当前工矿企业中应用广泛的电动机，其电机绕组的接线方法分星形接法Y和三角形接法Δ，下面介绍错误接线带来的后果。定子绕组星形运行的电动机，其每相绕组承受的电压即相电压是电动机额定电压(电源线电压)的1/3倍(0.58倍)。若错接成三角形运行，即相电压升高至厂家规定的1.73倍。，电源电压380伏，星形运行，相电压为220伏，接成三角形，则相电压升高至380伏。由于绕组的相电压升高，铁芯将高度饱和，铁芯磁通的励磁电流将急剧增加，再加上负载电流，定子绕组电流大大增加，将使绕组铜损急剧增大，终导致定子绕组过热烧毁。

确定二次侧a点（若为星型接线需要先确定y点）由于AX与ax绕组在同一铁芯柱上，故UAX与Uax平行或在一条直线上。从绕组接线图知b与x共点，可以看出UAX与Uax只可能是平行，不可能是共线。相量图上A在X的右上方，a也必须是在x的右上方。根据绕组接线图极性端A在非极性端X的右上方，所以极性端a也必须在非极性端x的右上方，从而确定出a点的位置。根据相量互差120°确定出其他相量。根据UAB与Uab的夹角，确定接线组别。
