GD^2 is the metric equivalent of WK^2

There are ways to measure the approximate rotor "moment of inertia" or GD2 value, but I suggest you contact the manufacturer of your motor since they should be able to provide this value as part of the specifications.

Unless you know the weights and distances from center of all the rotor components, this cannot be calculated. Instead, you look it up in the motor data, or ask the manufacturer.
