摘　　要：采用固定频率的PWM电路TL494和频压转换芯片LM2917设计了高性能的反应式步进电动机调频调压驱动电源。分析了步进电动机调频调压原理,介绍了系统硬件电路及软件实现方法,使电机有效地抑制震荡,拓宽了其运行范围,提高了系统的可靠性。The high-performance driving power of stepping motor based on a fixed frequency PWM circuit TL494 and a voltage-frequencyconverter circuit LM2917. The principle Frequency Modulation and Voltage Modulation of stepping motor were analyzed in paper. It mainly introduced hardware circuit design and software program implementation method of this system,this method can effectively reduce the concussion and keep the torques constant of the Reaction Stepper Motor,the approach improves the system reliability.
