Abstract
A magnetorheological brake device has a stationary holder and two brake components. A first brake component is connected to the holder for conjoint rotation and extends in the axial direction. A second brake component includes a hollow sleeve part which can rotate about the first brake component. A gap is formed between the first and second brake components. At least one, two or more rotatable transmission components are arranged in the gap. The gap is filled with a magnetorheological medium. The first brake component has a core which extends in the axial direction and is made of a magnetically conductive material, and an electrical coil which is wound about the core in the axial direction, such that a magnetic field generated by the electrical coil extends across the first brake component.

1-30. (canceled).
A magnetorheological braking device, comprising:
- a fixed holder;
- at least two brake components, including a first brake component connected in a rotationally-fixed manner to said holder and extending in an axial direction, and a second brake component having a hollow sleeve part rotatably mounted about said first brake component;
- at least one, two or more rotatable transmission components disposed in a gap formed between said first and second brake components;
- a magnetorheological medium at least partially filling said gap;
- said first brake component having a core extending in an axial direction and formed of a magnetically conductive material, and an electrical coil wound axially around said core, wherein a magnetic field of said electrical coil extends transversely through said first brake component.
A method of operating an appliance, the method comprising:
- providing an adaptive braking device with a rotatable brake component for manual rotation;
- and
- controlling the braking device in dependence upon the manual rotation of the rotatable brake component and by way of a command that is identified by way of sound recognition.
