I am slowly trying to learn something other than controls, and I am having trouble understanding this "torque fighting" you are speaking of. Could somebody explain this phenomena to me?

Thanks,

Also, though at 40A the larger CIM is producing more torque, it's moving much slower while doing so, as others have mentioned. A better indication of which motor is "more powerful" is to look at, as you might guess, the power. The smaller CIM has a power of 250W -- more than that of its larger cousin.

At any rate, the 40 amp breakers don't trip at 40A anyways--it's significantly higher for a short period of time, so the torque would increase as well.
