| Abstract: | The paper introduced a solution in subdivided driving of stepping motor by means of EDA technology providing PWM control waveform.Using embeded EAB in FPGA to compose LPM-ROM,store PWM control waveform data which stepping motor each phase subdivided driving current needed.The magnitude comparator designed with FPGA generates several PWM current waveform synchronously,to realiz the step angles even division control for four-phase stepping motor.The design reduced exteral circuit and had high control precision and goog control effect. |
