摘要
为了实现直流电动机的无极调速,提出了以MC9S12XS128单片机为核心,利用MC33887H桥功率驱动芯片构建PWM无级调速控制系统。该系统可以减少主回路电子器件,起停时对直流系统的冲击小,能够满足调速范围大、精度高的性能需求。
In order to realize stepless speed control of DC motors, a PWM stepless speed control system based on MC9S12XS128 microcomputer is introduced, using MC33887H bridge power driver. The system can reduce the main loop electronic devices, and has small impact to DC system while starting and stopping. The control system can meet the requirements of large speed range and high precision performance.
