  3. Question- I am checking a brushed DC motor used as a fuel pump. It has 8 commutator segments and uses permanent magnets. I am checking the amperage draw on the motor using a current probe. My question is, when is the motor current draw highest, when the brushes are directly on the commutator segments, or when the brushes are bridging two segments? Thanks!
