| Abstract: | The paper introduces a basic kind of method of DC-motor speed modification based on PWM theory. Showing some relative knowledge upon DC motor speed modification, the PWM theory and the way to implement. It emphasizes on the way for carrying out PWM signals based on MCS-51. This paper still provides a method for modifying the speed of DC motor by way of taking count of data and time delay by software. It offers a sort of efficient method for the DC motor speed-controlling system by using software. It is proved to have very good effect in the practical application of the "Finish Roll Electric Machine Controling system". |
