The invention relates to a brake arrangement and a method for operating a brake arrangement comprising the following: - an armature disc, - a coil core, - a coil, - a brake lining support, - a part which has a braking surface, in particular a bearing plate, - permanent magnets, - a shaft, and - a driver. The armature disc is arranged in a rotationally fixed but axially movable manner relative to the coil core, and the coil, the coil core, and the part which has a braking surface are connected, in particular in a rigid manner. The shaft is rigidly connected to the driver, and the driver has an outer toothing which meshes with an inner toothing of the brake lining support such that the brake lining support is connected to the driver and thus to the shaft in a rotationally fixed but axially movable manner. The brake arrangement can be brought into a release state or an engaged state. In the release state of the brake arrangement, the armature disc is arranged closer to the coil than in the engaged state of the brake arrangement, wherein a spring force generated by spring elements acts on the armature disc; the permanent magnets are arranged such that the armature disc can be held by the permanent magnets in the release state; and the armature disc is held by the spring force in the engaged state. |
