Closest I can think of is flywheel "battery" storage tech many of which do have magnetic bearings and also some way to get power in and out of the flywheel so basically a motor. It's not exactly what you're looking for but there's prior art out there.

I think air bearings exist? Maybe some prior art to consider

maglev but those do linear acceleration instead of rotational. seems tricky though for cars with such uneven surfaces.

I wonder if that is even possible since the whole point of the motor is an imbalance of magnetic forces.
