挖掘仪器设备潜力 改进机电教学实验

Tapping Devices' Potentialities To Improve Electromechanical Experiment

通过对废旧微机磁盘驱动器工作原理的分析，用驱动器中的步进电机及驱动电路与单片机结合可设计组装一套完成数字控制实验的装置，从而变废为宝，挖掘废旧仪器设备潜力，节约实验和设备经费，改进实验教学。

Studying the principle of operation of computer's floppy driver and utilizing the stepping motor and drive circuit of an old and rejected driver and a single-chip processor,one can design and assemble a device to carry out digital control experiment with.Thus the potential of old and rejected devices can be tapped,fund of experiment and equipment can be saved,and experiment teaching can be improved.
