步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件；步进电机的动作方式比常规电机显得更为灵活、方便，多用性。因此它已经涉及到了机械、电子及计算机等众多相关行业，如：打印机，绘图仪，机器人等应用。本系统就是初步探讨步进电机的控制方法，为以后深入学习电机的控制打下基础。-Stepper motor is the electrical pulse signal into an angular displacement or linear displacement of the open-loop control components　stepper motor moves the way it is than conventional motor more flexible, convenient and multi-purpose nature. Therefore it has been related to the mechanical, electronic and computer and many other related industries, such as: printers, plotters, robotics applications. Preliminary study of the system is stepper motor control, motor-depth study for the future lay the foundation for control.
