The motor curves can be very accurately matched with some testing and good programming, basically making tables and having different values at different point for the motors so they run on almost same RPMs always. Also if there is a very minor different its unnoticeable, and because they are not using the transmission on their drill, all are raw DC motors, they will help each other, not overlaod each other.
Though it would be interesting to see them go against someone with 3 motor drive. They both might reset their breakers  . |
I've updated my post slightly. What im really saying is that it is useless to sue the 6 biggest motors when you could get essentially the same effective power out of 2 motors (and not even the drill and chip). Of course they may be trying to keep their motors in the most efficient part of the curve, but all the extra stuff that this drivetrain requires (bigger, heavier gearbox, more wiring and controller, etc) probably kills that gain in efficiency
