| 摘 要： | 为了实现永磁式步进电机的细分控制，采用PIC18F2331单片机作为主控单元接收外部的脉宽调制（PWM）步进电机控制信号，并辅之以外部功率驱动电路完成了步进电机细分控制器的硬件设计，并应用C语言编写了相应的PWM信号至步进电机控制信号的转换程序，实现了对2／4相步进电机的开环细分控制。此外，还利用单片机的串行通信模块，设计了与计算机的串行通信电路，方便了系统的调试和监控。测试结果表明，该控制器能实现对步进电机的细分控制。

| Abstract: | Aiming at realizing a permanent magnet stepper motor microstepping management,using PIC18F2331 micro-programmed control unit(MCU) as main control unit detecting external pulse width modulation(PWM) control signal and the other external power drive circuit,the hardware was developed for that controller.Furthermore,with the C programming,the PWM duty ratio detected by PIC18F2331 was converted into the stepper motor control signal to drive a 2/4 phase stepper motor.Additionally,the online debug and monitoring ... |
