How to incorporate rotor inertia equivalent in wheels in SW motion?

Hey,

I'm doing a simple study on rolling of wheel and braking action on it after some time. But in practical their is some effect due to rotor inertia of motor on it. And if we know the rotor inertia from catalog how to find equivalent inertia of that rotor on wheel so that we can simulate it's effect in Solidworks motion.

Thanks
