Hello Guys,
I know that you can control a DC motor using H-brigdes and a few FETs. By doing this you gain the speed control by selecting the duty cycle. However, I got this issue on setting the Frequency of the systems. How am i supposed to get to calculate that? Does it have anything to do to the MAX RPM of the DC motors?
Other thing is the reverse voltage created by those guys. It is good practice to set a Diode for that matter. However, how do i calculate the voltage and current that are going to be generated by stopping powering the mottor?
Thank you All...
