That part number is how you tell what rotor is in the motor, as you can change them to tweak how the motor performs. I wanna say I ran a softer 272 rotor in my 2wd buggy when I ran the M3 reedys. As an example.
The rotor in a brushless motor is just magnets though right? Looking at the link you posted - 275 isn't there - each number though seems to refer to a number of turns - maybe that's just the default rotor for the motor?
Do you know what physically changes between the rotors?
