步进电机是一种将电脉冲信号转换成角位移或者线位置的机电元件,具有易开环控制和无累积误差的优点.但是步进电机在一些精度要求高的场合会存在一些低频振荡、高频失步等问题,使步进电机运行很不稳定,因此提出了步进电机的细分驱动控制.
本文介绍了四相反应式步进电机的工作原理,分析了FPGA驱动和单片机驱动器的优缺点,比较了脉宽调制式细分驱动电路和斩波式细分驱动电路原理的优缺点,引出了通过FPGA芯片控制PWM信号的占空比来调整步进电机的各相电流,实现了步进电机的正转和反转,正常运行和细分运行的工作方式.

Stepper motor is an electromechanical component which can convert electric pulse signal into angular displacement or line position,and it has the advantages of easy open-loop control and no cumulative error.However,there are some problems for stepper motor in the applications where high precision is required,such as low-frequency oscillation,high-frequency step-out,etc.,leading to the unstable operation of stepper motor,so the subdivision drive control of stepper motor is proposed.This paper introduces the working principle of four-phase reaction-excited stepper motor,analyzes the advantages and disadvantages of FPGA drive and microcontroller driver,compares the advantages and disadvantages of the principles of PWM subdivision drive circuit and chopper subdivision driver,and proposes using EPGA chip to control the duty cycle of the PWM signal,thereby adjusting the current of each phase of stepper motor.On this basis the forward and reverse rotation,the normal operation and subdivision operation of stepper motor are realized.
