Re: paper: 4 CIM versus 6 CIM theoretical calculations
1. Mechanical power output is not everything. You need to have useful power; proper gearing. However, yes, having more mechanical power output won't hurt.
2. How do you magically draw a hard limit of 200 (or whatever) amps without effecting voltage input to the motors? Though you may be "limited" to 200 amps, when you're drawing this much current, voltage dips due to both surface depletion (?) and voltage drop in the loads to the motors. This shouldn't be ignored. When you drop away from the 12V, the motor curve you use up there is no longer valid.
Look into using kV and kT values to model things and take this voltage drop into account.

When I see stuff like that, sometimes I say, "That's BRILLIANT, why didn't I think of that?" But I never like the answer.
