　1、步进电机的工作原理：

　　步进电机的工作原理是通过控制接线线圈的电流变化而实现转动的，只要以恒定的频率控制线圈的电流，就可以使电机实现转动，从而实现的位移控制。

　　2、步进电机的驱动器原理：

　　步进电机的驱动器原理是把脉冲信号转换成步进电机所需要的电流信号，然后把电流信号输入到步进电机中，步进电机就可以实现转动了。

　　3、步进电机的驱动器原理图：

　　步进电机驱动原理图主要由电源、控制器、脉冲转换器、步进电机以及驱动器组成，其中电源主要提供直流电源，控制器主要控制脉冲信号的频率，脉冲转换器主要把脉冲信号转换成电流信号，步进电机则通过电流信号完成转动，驱动器后把电流信号输入到步进电机中。

　　步进电机驱动器的工作原理

　　步进电机在控制系统中具有广泛的应用。它可以把脉冲信号转换成角位移，并且可用作电磁制动轮、电磁差分器、或角位移发生器等。

　　有时从一些旧设备上拆下的步进电机(这种电机一般没有损坏)要改作它用，一般需自己设计驱动器。本文介绍的就是为从一日本产旧式打印机上拆下的步进电机而设计的驱动器。本文先介绍该步进电机的工作原理，然后介绍了其驱动器的软、硬件设计。
