三相同步电机的接线方法一般采用星形接法和三角形接法。

　　星形接法：先将上部的线圈尾端相连在一起，再把下方的3个接线柱，依次接入三相电源火线。

　　三角形接法：先确认首尾端，然后将首尾相连，外接电源火线即可。

　　电机大于20kw时，则好采用三角形接法开启，然后再转星形接法进行运行。

　　三相同步电机怎么接线

　　电动机采用什么接法是和工作电流有关的，电动机内部绕组的截面积的情况下，电压高用三角形接法，电压低用星形接法。一般情况下 大功率电机都是采用的三角形接法，因为可以降低负载电流。日常情况下家庭一般用的都是单相电机，很少会出现三相电机。采用三角形接法的时候加在电动机线圈上的电压为线电压，采用星形接法的时候加在电动机线圈上的电压为相电压，线电压和相电压的关系式：√3U相=U线。因为电动机在做好之后其内阻就决定了，根据相同功率情况下，电压越高，电流越小的选择电动机的进线接线方式。另外附带说一下：电动机烧不是因为电压高，而是因为电流过大，因为是电流流过导体才产热，而不是电压加在导体上导体就发热的。
