摘要
设计了专门用于自动门控制系统的四相步进电机驱动器。采用可编辑逻辑器件 CPL D来实现环形脉冲分配器的功能 ,选用的是一能的 MOSFET功率器件 ,并且采取了过流过热保护措施 。
In this paper, the design of four-phase step motor used in automatic gate control system is introduced, by selecting the high performance MOSFET power driver and using the CPLD to achieve the function of circuit pulse allocation,the reliability and stability of system is improved greatly.
