摘要
系统设计采用高性能单片机构成直流电动机PWM调速系统,由单片机输出控制信号并通过专用芯片产生PWM波形来控制电动机转动与速度,其运行状态由反馈电路进行数据采集,并将采集信息反馈给单片机进行数据分析处理,并将当前的电动机运行状态显示出来。
The single chip processor is adopted in the design of the PWM speed regulation system of DC motor. The PWM wave form, is generated by this processor and the motor is controlled by special control chip. The data of operating state is firstly sampled and processed through feedback circuit,then the processed data is fed back to the single chip processor and the data is analyzed and processed,finally the current operating state of motor is displayed through display.
