Abstract
A rotatable element is arranged on a supporting member. The element is freely rotatable and displaceable radially by being held in position by two portions attracting each other, said portions being made of magnetic material, and that a plane slot separates the supporting member and the element. The driving of the element can be effected thereby that the element forms or incorporates a rotor in an electromotor, the stator of which is arranged in an area of the supporting member.
