The Moment of Inertia for a flat disc with a hole in the center is: I = M/2 · (square(R1) + square(R2)) Where I = Moment of Inertia M = Mass (weight) of the disc R1 = Radius of inner hole R2 = Radius of the disc

The moment of inertia is dependent on the external object, but how to estimate damping ratio of a dc motor is still not clear.
