| | | | Hi Mark, (...) is it really true that there is a square law for PWM? Can you explain the reason why this is so? I understand that this is true if you change the voltage (half the voltage gives half the current so a quarter of the power). But I (...)

| | | | | (...) I couldn't call myself an expert either! In your second way of looking at it, the full voltage and full current are already multiplied to give full power for part of the time. I=(Vcc-Eb)/R Current I, Voltage Vcc, Back EMF Eb and motor (...) (20 years ago, 14-Mar-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)
