Dynamics of magnetic gears — •Stefan Hartung, Simeon Völkel, and Ingo Rehberg — Universität Bayreuth

The coupling of two rotating spherical magnets is investigated experimentally. Those motions where the driven magnet is phase-locked to the driving one are so-called cogging free couplings [1]. We find that configurations not following this condition show a more complex dynamical behavior. The experimental results are compared to a model based on pure dipole-dipole interaction. Technical applications of these kinds of couplings are foreseeable particularly for small machines.
