1、本模块由 45BC340C 型步进电机及其驱动电路组成（一步进电机：一般电动机都是连续旋转，而步进电动却是一步一步转动的，故叫步进电动机。每输入一个脉冲信号，该电动机就转过一定的角度（有的步进电动机可以直接输出线位移，称为直线电动机。因此步进电动机是一种把脉冲变为角度位移（或直线位移的执行元件。步进电动机的转子为多极分布，定子上嵌有多相星形连接的控制绕组，由专门电 源输入电脉冲信号，每输入一个脉冲信号，步进电动机的转子就前进一步。由于输入的是脉冲信号，输出的角位移是断续的，所以又称为脉冲电动机。随着数字控制系统的发展，步进电动机的应用将逐渐扩大。步进电动机的种类很多，按结构可分为反应式和激励式
