Speed Stabilization in Rotation: An Analogy with Cyclotron Motion.

A mechanical counterpart of cyclotron motion is found. The configuration of the corresponding device is determined; it may be called a stabilized rotor. The natural rotational frequency (speed) of the rotor is fixed. (It does not depend on the moment of inertia or the angular momentum.) Remarkably, it is the same as the natural oscillation frequency of a pendulum with identical parameters. [ABSTRACT FROM AUTHOR]
