Looks like the 81% "Speed Loss Constant" is directly responsible for the 41 pounds of force required to sustain constant motion.

Also, the 102 amps appears to be the motor torque required to break traction, and is driven by the "Contact Coef of Friction".


John, if you are lurking, could you please shed some light on what are the physical contributors to this "Speed Loss Constant"? The only thing I can think of off-hand would be the rolling friction and the friction in the wheel bearings, since all the drivetrain friction should already be included in the "Drivetrain Efficiency" number, n'est-ce pas?
