用微机直接控制的步进驱动系统

Stepping Drive System Controlled by Microcomputer

与直流电机、变频调速电机相比较，步进电机具有定位准确和可无级调速等优点。介绍了一种全新的步进驱动系统，它用计算机串口进行控制，功能强。

By comparison with DC motor and frequency changer speed regulation motor, stepmotor has a lot of advantages of accurate positioning and stepless speed regulation etc. A novel stepping drive system is introduced. The system's control is made by serial interface of computer, which has a good performance and reliability.
