The magnetic bearings themselves have sensors that tell you all the information you need to ensure proper operation of the motor. The reliability is bar-none in the industry.

As for the forces, tonfazg... what? You have to be a bit more clear but yes, the coin CAN show if there are vibrations on the stator. If the stator is vibrating, the coin cannot stay up. The isolation between rotor and stator comes from the bearings - normally there is contact so vibrations are transmitted but not here.

Tonfazg is right. need less to say.

They probably used a little drop of super glu haha

Now use an ironless core axial motor/generator, attatch a large fly wheel and put this whole system in a close to perfect vacuum and power it up with solar panels and see how much energy can be stored and how long or fast the energy can it be utilized.

Zaaaaaaaaaaaap...

.. advantage of vibrations and can tel if a motor is behaving in a way it should. I dont kow..i am kinda skeptic if it is such a good thing to get, i assume it is expensive.

Well, you dont have to have direct contact with the stator...force that is causing the rotor to rotate, is the same that would make stator spin if it wouldnt be screwed down, so if rotor is made to vibrate, the stator would vibrate also, coin cant show is there vibrations on stator. When coin falls, it falls like it is in strong magnetic field....i am not saying that it is holding it down but why is magnetic field at that point of motor? Also i saw some god diagnostic tools that take advantage..
