Default Motor specifications from dynos and etc

I'm curious, as i'm still kind of new to the numbers that are taken from a motor dyno or from a certified motor. What do those numbers signify? Like i'm guessing it's telling on its efficiency and/or power of each motor. But how do i decipher?

my guess looking at those numbers its a 13.5 1s ??

first one is stator resistance of the 3 winds, lower the better
second is rotor strength, higher the better depending on application
third I believe is current draw, lower the number more efficient it is,
and RPM is well RPM,

I don't know if that helps you or not as you can only really compare how good it is compared to other same motors

IE:

The specifications on the certified motor sticker are as follows:

Stator resistance values at 72 degrees F, these obviously are very temperature sensitive.
Rotor strength values at 72 degrees F.
Amp draw and RPM at 1 cell voltage (free rev).
Amp draw and RPM at 2 cell voltage (free rev).
Amp draws are set with the Gforce measuring machine.

Remember that because standards and calibration differences between Dyno manufacturers, these measurements are not a true form of comparison. Every manufacturer has their own way of interpreting the numbers a Dyno can produce.

Personally I only use these test to compare motors is when I'm comparing other motors I have.

Do you really think Trinity is putting RPM and amp draw numbers on their motors with a Gforce machine? I would be willing go bet it is a Motolyser(exclusive distributor) and very accurate or a machine they built.
