交流电机的核心部分是一个磁场。磁场是靠电流在定子绕组上创建的，这个磁场产生的空间范围随绕组上电流的变化而变化。在定子绕组中的电流正弦变化时，磁场也会在空间中旋转，这就是“旋转磁场”的概念。而转子绕组内的电流电流会依据旋转磁场的射入角度变化，并且会产生自己的磁场，导致其扭曲和跟随旋转磁场运动。终，这些不断扭曲的磁场的相互作用，以一种在转子内产生扭矩的方式，将转子带动旋转。

有了“旋转磁场”的工作原理，我们就可以通过改变定子电源的电流变化方式，产生特定形状的旋转磁场，将其作用于转子上，控制转子的转速和方向。实际上，现代电机通常采用电子电路，采用频率变换器控制电压和电流，以产生需要的旋转磁场。而且，交流电机的定子和转子的结构都非常复杂，通常由铜线绕组和铁芯组成，需要多个相互配合的部分组合成一个完整的电机，并配有适当的控制器，以使其能地控制电机的状态和动作。
