No, it does some mechanical work, it's spinning. It is overcoming bearing friction and wind friction. No doubt it is performing mechanical work. But to be OU, it must perform more mechanical work than electrical input. But the freakin' motor would not work without magnetic floating bearings. And windage is virtually zero from the geometry. But so is the electrical input.
Put a string on the axle and see how much weight it can lift. My bet is a fraction of a gram. I have no doubt that when the energy balance is calculated, the efficiency of the motor will be <0.5.
