Abstract
A device component has a magnetorheological brake device with a static holder and with two brake components. A first brake component is rotationally fixedly to the holder and extends in an axial direction. A second brake component has a hollow, rotary part which is rotatable about the first brake component. An encircling gap between the first and second brake components is filled with a magnetorheological medium. The first brake component has a core of magnetically conductive material which extends in the axial direction. An electrical coil is wound axially around the core and spans a coil plane. A magnetic field of the coil extends transversely through the first brake component. A maximum outer diameter of the electrical coil in a radial direction within the coil plane is greater than a minimum outer diameter of the core in a radial direction transversely to the coil plane.
