反应式步进电机使用外部交替电源来产生磁场，而转子将受到磁场的作用而旋转。该类型的步进电机需要较少的元件，因此结构简单，成本较低。但是，由于反应式步进电机是依靠交替电源产生磁场，因此在低速运行时可能会出现不稳定性和噪音问题。

　　永磁式步进电机则使用固定的永磁磁场来驱动转子，因此不需要外部电源。该类型的步进电机通常具有更高的精度和的控制性能，因此在某些特殊应用中更为常见。但是，永磁式步进电机的成本通常较高，因为需要使用更多的元件来控制磁场。

　　永磁式步进电机则是利用永磁体和定子绕组之间的磁作用力来实现步进运动。在脉冲控制下，每给定一个脉冲，永磁体都会产生一个特定步进角度的运动。永磁式步进电机的优点是步进角较大，扭矩稳定性较好，但缺点是不易控制。
