本设计系统地设计了双直流电动机调速的实时同步调速控制系统。经过多次的运行与检测，实践证明该电路工作稳定，显示清晰。其有以下特点：①调速性能好。电动机在一定负载的条件下，根据需要，能人为地改变电动机的转速。直流电动机可以在负载条件下，实现均匀、平滑的无级调速，而且调速范围较宽。②能实现双电机的同步无误差控制。在外负载改变第一个电机的转速时,另外一个电机可以跟随第一个电机的转速，实现同步无误差控制。采用全汇编语言设计，值得参考。-The design of the system design of real-time synchronization speed control system of Dual DC motor speed. After running and testing times, and it proved that the circuit is stable, clear display. Which has the following characteristics: ① speed performance. Under certain conditions the motor load, as required, to artificially change the motor speed. DC motor can be under load, to achieve a uniform, smooth, stepless, and a wide speed range. ② to achieve dual-motor synchronous error-free control. When the external load changes the first motor speed, the other motor can follow the first motor speed, error-free synchronization control. With full assembly language design, it is also useful.
