有不少电工对单相电机的接线搞不清。我先对单相电机的正反转原理讲一下。单机电机里面有二组线圈，一组是运转线圈（主线圈），一组是启动线圈（副线圈），大多的电机的启动线圈并不是只启动后就不用了，而是一直工作在电路中的。启动线圈电阻比运转线圈电阻大些，量下就知了。启动的线圈串了电容器的。也就是串了电容器的启动线圈与运转线圈并联，再接到220V电压上，这就是电机的接法。当这个串了电容器的启动线圈与运转线圈并联时，并联的二对接线头的头尾决定了正反转的。比起三相电动机的顺逆转控制，单相电动机要困难得多，一是因为单相电动机有启动电容、运行电容、离心开关等辅助装置，结构复杂；二是因为单相电动机运行绕组和启动绕组不一样，不能互为代用，增加了接线的难度，弄错就可能烧毁电动机。

我公司主要经营西门子abb,施耐德等国外多家品牌，产品涉及变频器，仪器仪表，变送器，可编程控制器plc和人机界面。
