Hello everyone !
I would like to control the DC motor speed by a proportional command.
To do that, I would like to use a PWM available on a PIC.
My block diagram will look like something as following : http://hpics.li/e766676
My question is : What is the link between the PWM and the current ?
I am a totally beginner in this field. So let's me explain if I am right.
By changing duty cycle, I will change the tension and to some extent the current that the motor needs to work.
So, how can I know which duty cycle, which PWM value matchs with the current to the motor ?
Thank you for your help.
