Abstract
An electromagnetic brake (), in particular for an electric drive is provided, having a brake body (), which is provided with a sleeve-shaped permanent magnet (), an electromagnet () with an exciting coil (), an external ring in the form of an external pole and an internal ring () in the form of an internal pole, wherein an armature disc () rotatably connected to a shaft is attractable against the brake body () or the external or internal ring surfaces by the permanent magnet () force acting against a return spring force. When the exciting coil is powered, the permanent magnet () magnetic field is compensated in such a way that the armature disc () is lifted up from the brake body () by the spring force, thereby allowing the brake to be released. A radial cross-sectional dimension or cross-sectional thickness d of the permanent magnet () is smaller than the axial dimension thereof and a spatial arrangement, viewed in the axial direction, is provided between the armature disc () and the exciting coil () in the area radially external with respect to the exciting coil () or the housing thereof.
