PWM
Hi! Thanks for the quick reply! I know the DC motor is kind of a "low pass filter", it suppresses the AC component of the PWM signal. The rest is the DC component what equals the average value of the PWM. Is this correct? So, this is the reason why I should use the Vin*Duty formula by motor...- mjoco

PWM
Hello! I want to ask something about the Pulse Width Modulation. Which voltage value is more important? Average (V*duty) or RMS (V*sqrt(duty))? If I calculate the work, then the PWM's RMS value represents the equal DC voltage. By contrast every one uses the average voltage formula - etc. 10V...- mjoco
