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.

That's what I was thinking. These numbers (I recently found out) came from some IEEE phD who was asked to find all the specs on these motors when running in between 30 and 40 amps.

From my basic knowledge, wouldn't the higher torque at lower speeds mean that my gearbox will end up smaller, less weight, and will still push just as much as an equivalent box with a CIM?

Also, only having one motor eliminates the issue of torque fighting when there are two motors on a gearbox.
