上述动作反复进行，电机转子就能继续转动。从以上单相步进电机的运行原理看出，单相步进电机的电磁转矩只在定子电流变换时产生，故其平均转矩比两相以上的电机要小得多，响应脉冲频率也在100pps以下，故其用途受到很大限制，只能在响应脉冲频率比较低的轻载下运行。时钟、车用计时器（发动机计时器）、水表计数器等。下图为另一种单相步进电机结构的照片，左边为电机整机，其次为电机线圈，再次为定子铁心，后是永磁转子。

但是存在这么一个现象：漏电保护器不安装，只安装空气开关或者刀开关。漏电保护器不安装的理由是什么呢？我们可能也会经常遇到这种情况，无缘无故的漏电保护器就跳闸了，如果不能发现哪地方经常漏电，只要通电，保护器不久就又一次跳闸了。为了不影响使用，干脆就将漏电保护器给卸载掉，只保留空气开关。实际上，省略了漏电保护器就存在了巨大的安全隐患。保护器跳闸是因为肯定有漏电的地方，既然漏电，那么人就有可能发生触电的情况。
