Yes there'd be starting torque inertia and other things trying to stop it starting.
The biggest part of that would be the bearing stiction, because nothing esle is stopping it moving except the bearing and Newtons 2nd law.
That's the reason for careful balancing - there's less likelyhood of the motor getting overloaded if there's no 'weight' on the system.
The motors for the keck scope are about 1/2hp - and the thing weighs tons but it is balanced.
Your motor loading is likely to be rated on wind resistance and interference with external parts like collision with the mount.
