"Null-E" Magnetic Bearings - Filatov (2002) (Correct)
....2.6 Bearings stabilized by a gyroscopic torque Note that the suspensions utilizing interaction of conductors with permanent magnets work only in the dynamic mode, i.e. when the rotor rotates. It was shown recently, that a dynamically stable suspension can be realized using only permanent magnets [90, 91, 92, 93, 94, 95]. This does not contradict Earnshaw s theorem which is valid only for stationary systems and does not consider dynamic effects caused by rotation. Unfortunately, this method was found difficult to use in practice because of low stiffness and load capacity and because the stability is very ....
