Smaller brushes generate lots more HEAT. I smoked my stock Hitachi motor with a controller upgrade and I was only set to 400 amps max. I replaced it with a D&D and it does not get very hot at all with similar running conditions. Bigger brushes lower the resistance at the commutator which generates far less heat.
