摘要
步进电机是一种将脉冲电信号变换为相应的角位移或直线位移的数控元件,其性能在很大程度上取决于驱动电路的优劣。本文阐述了驱动电路的基本组成及工作要求,分析了几种典型驱动电路的特性,结果表明:恒流斩波技术将具有非常广泛的应用前景。
The stepping motor is a digital control component which changes the pulse signal into relevant angle or straight-line displacement,its performance lies on the driver. The paper expatiates the basic composition and requirement of the driver , analyses several typical circuits, the results indicate the technique of the constant current wave has a wide range ofprospect.
