摘要
本文介绍了一种步进电动机绕组电流可调的斩波型驱动电路的工作原理和基本特点,并以拖动C_(620)型车床的切削为例,阐述了这种电路的实验结果,提供了实测的有关数据和照片。
The operational principle and basic features of a chopping drive circuit is introduced. with this circuit, adjustable winding current to the steping motor could be obtained. With driving the ma-chining on C620 lathe as example, the experi-mental result of this circuit is described. The actual measuring data and photo are provided.
