学习方法。找个做非标自动化的公司，跟着电气工程师从基础的电气元件认识和接线使用开始学习，2个月左右，对硬件有认识，可以接触简单的控制程序，可以使几个点位的控制。循序渐进，逐步加深。目前非标的公司像江苏昆山、郑州高新区都有很多。报培训班，系统学习。但不建议，大部分培训班还是教些基础的东西，还要从实践做起。若已经报过，可以再淘宝上面买些PLC板子，100元左右，和目前PLC的编程是一样的。不断深入学习。

三相异步电动机的基本接线。三相异步电动机绕组出来的六根线可以分为两种基本的接法：三角形△接法和星形接法。六根线=三个电机绕组=三个首端+三个尾端，万用表测量同绕组首尾端相通，即：U1—U2，V1—V2，W1—W2。1，三相异步电机三角形△接法。三角形△接法就是将三个绕组首尾端依次相连，构成三角形。接法：2，三相异步电机星形接法。星形接法就是将三个绕组的尾端或者首端相连，另外三根线作为电源接线。
