Abstract

A magnetic coupling is provided having two rings that are arranged concentrically in relation to one another, which are each mounted to be rotatable in relation to one another. An arrangement of at least three magnetic dipoles is respectively arranged on both rings, the magnetic dipoles facilitating magnetic coupling of the rings and a transmission of torque from a driving ring to a driven ring of the two rings. The magnetic dipoles of the arrangements at the driven ring and/or at the driving ring is/are aligned such that two like magnetic poles, which adjoin one another on the respective other ring, are always followed by an unlike magnetic pole, and the magnetic poles adjoining one another at the respective other ring are arranged in a manner corresponding to one another such that the two rings are magnetically coupled in an equilibrium position.
