摘要
在对步进电机细分驱动原理进行分析研究的基础上,提出一种基于FPGA控制的步进电机细分驱动器。利用FPGA中的嵌入式EAB构成LPM-ROM,存放步进电机各相细分电流所需的PWM控制波形数据表,并通过FPGA设计的数字比较器,同时产生多路PWM电流波形,实现对步进电机转角进行均匀细分控制。
In this paper,a divided driving circuit for stepping motor controlled by FPGA is put forward,based on the analysis of the principle of stepping motor divided driving. Using embedded EAB in FPGA to compose LPM-ROM,store PWM control wave form data which stepping motor each phase subdivided driving current is needed.The magnitude comparator designed with FPGA generates several PWM current waveform synchronously,to realize the step angles even division control for three-phase stepping motor.
