What about hooking it up to a big flywheel?

How could you connect a maglev-suspended motor to a drivebelt for example? The belt would either slip or the axle would grind against the casing if the belt is tightened...

And big blowers push substantial amounts of air, newtonian physics tell us a similar, opposite force should be exerted onto the fanblades themselves. Now, as the air in the fan casing is rotating as it moves it's not going to be completely in the opposite reaction, but some will create a reaction thrust on the fanwheel, and it will be angled in an odd direction that could be problematic for a pulsed maglev motor. If the axle shifts its angle of rotation, how would that affect the sensor that controls the electromagnetic solenoid powering the thing?

If there are enough magnets positioned properly, any displacement of the rotor will push it closer to a repelling magnet.

Since the repulsion goes up by the inverse of the distance squared, it gets harder to grind it into the side.

If done properly, only the most extreme cases will overcome the magnet's strength. Usually there's a backup standard bearing to handle these cases.

A properly made blower shouldn't to make enough thrust to overcome its own bearings.
