摘　　要：介绍了BYG通用系列二相步进电机最常采用的的单极性和双极性2种驱动电路的设计方案,从原理上体现了二相步进电机的控制方法,增加了步进电机驱动电路设计的灵活性。二相步进电机的单极性和双极性2种驱动电路设计都采用了一片可在线编程的单片机AT89S52作为控制器,由达林顿功率管TIP142组成的电路作为驱动器,电路结构简单,设计思路清晰。同时,比较分析了单极性和双极性这2种常用驱动电路设计方案的特点、区别及在应用中的选择方法。The design scheme of common unipolar and bipolar driving circuits for BYG general series of two phase stepping motors were introduced, which illustrates control methods for two phases stepping motor theoretically and increases the flexibility of driving circuit design for stepping motor. The AT89S52 on-line programmable single-chip computer was used as controller in both unipolar and bipolar driving circuit designs for two phase stepping motor, and driving circuits were composed of TIPI42 darlington power transistors. The structure＇of designed circuit is sim- ple, and the design thread is clear. The feature, difference and selection method in use of unipolar and bipolar driving circuits design schemes were analyzed and compared in this paper.
