Abstract

A device for transmitting rotational motions without contact may include an inner rotor with at least one inner-rotor magnet and an outer rotor with at least one outer-rotor magnet. The inner rotor and the outer rotor are magnetically coupled to one another and rotatable along a rotation direction about a common axis of rotation. The at least one inner-rotor magnet and/or the at least one outer-rotor magnet may have a magnetization that is at least one of diametric, radial, and lateral. The at least one inner-rotor magnet may have a different type of magnetization than the at least one outer-rotor magnet.
