Abstract
A brake device comprises a stack of friction plates (6,7) compressible to have a braking effect between an armature (9) and a magnet structure (10,) the structure including a permanent magnet (11) urging the armature towards the magnet structure to effect braking, and an electromagnet (12) energizable to augment the effect of the permanent magnet, or to oppose it either partially or completely so as to release the braking effect.
