Beschreibung
Zusammenfassung:	The electromagnetic hysteresis brake, especially a yarn brake for textile machines, comprises a stationary brake magnet (1), which consists of inner and outer pole ring parts (2, 3) and a magnet winding (4), and a rotating armature (8), which is connected to a hysteresis ring (7) of permanent magnetic material. The hysteresis ring (7) projects into an annular air-gap (6) of the brake magnet (1), which is formed between the inner and outer pole ring parts (2, 3). At least one permanent magnet (5) is so arranged adjacent the magnet winding (4) that the magnetic field in the air-gap (6) is formed by cooperation of the magnetic fluxes of the electromagnet (4) and the permanent magnet (5). The magnetic flux of the electromagnet (4) can be adjusted in magnitude and direction in the gap by corresponding poling that it assists or counteracts the magnetic flux of the permanent magnet.
