Here is the argument, a claim is being made that on the 4 speed system with a resistor pack, the lowest speed is more likely to experience overcurrent/overheating issues due to the fact that it has the most resistance which will force the motor to draw more current to maintain speed than it would on the higher speeds with less resistance.
My thought is that the resistor drops voltage which in turn limits current and when more heavily loaded, the motor will simply slow down (which will of course result in a reduction of counter EMF and increase current draw but to what extent can it increase current draw with the resistor in series?)
I argue that the highest speed will be more likely to experience overcurrent/overheating because it bypasses the resistor and thus isn't as limited in available current.
