为了提高步进电机的运行精度,消除或减小振动现象,文章基于细分驱动技术,以单片机ATmega128为核心,应用恒流斩波PWM发生电路和H桥功率驱动电路设计了步进电机的驱动系统。系统控制参数通过上位机设定,以串口通信传给单片机。实验结果表明:电机运行平稳,振动噪音小,转矩大,精度高,系统具有良好的应用前景。 |
英文摘要: |
ln order to improve the running system of the stepping motor and to eliminate or reduce its vibration. the
driving system for stepping motor was designed in this paper based on the subdivision driving technology, which used
microcontroller ATmega128 as the core and PWM generation as the constant current chopping circuit and H power bridge
circuit. The controlling parameters were set on PC . which was transferred to microcontroller through the serial port. The
experimental results showed that the system had good performance. running smoothly with small vibration noise, large
torque and high precision. |
