gd2 is the value which is meant to check that whether a
given motor will mingle with an impeller or not. Its a
sought of age of fan and motor.
Technically , it tells us about the measure of the ability
of the motor to attain its a rated speed from rest.
This is calculated with the formula
4 x m x r2
m = mass of the impeller
r = radius of gyration
r shall be 0.4 times the radius of impeller
I hope its sought of clear now
