Drive Train design roadblocks

[henryBsick]

Dave and Mike did bring up 2 good points but for the sake of JVN calculation experimentation...
The 2 values for current draw relating to the two different speeds (gears) directly reflect the force it takes to rotate in each gear.
low gear-more rotations (from motor)-faster rotations (from motor)-less power req. to rotate-less amperage
high gear-less rations (from motor)-slower rotations (from motor)- more power req. to rotate-more amperage
I am not specifically familiar with the JVN calcs. but through my own calculations and driving in matches (while tripping the 40 amp breakers in high high gear) I believe that to be your answer.

This much I was aware of. I was referring to the JVN sheet's two current values for each gear. Both high gear and low gear have a number listed for "[High/Low] Gear Load Current Draw" and "Drive [High/Low] Gear Current Draw". The second (Drive...) is calculated as 2x the first. I was wondering what the reasoning was for this, and how to properly read it.
