摘要：<p>A flameproof electromagnetic emergency brake is described, which is fixed downstream of a kinematic mechanism of an apparatus to be controlled, and which comprises: - a magnet (3) with a coil (4) run through by electric current to generate the electromagnetic effect; - a movable keeper (8) adapted to be attracted or pushed back by the magnet; - a fixed keeper (10); - a series of floating disks (11) alternated with a series of friction lining disks (12), disposed between said movable and fixed keepers and coaxial thereto, the absence of electromagnetic effect being such as to cause a braking effect due to the thrust of the movable keeper towards the fixed keeper, the presence of electromagnetic effect being such as to attract the movable keeper towards the magnet; - a rotating shaft (5) arranged axially in the brake, and axially inserted into said magnet, movable keeper, fixed keeper, floating disks and friction lining disks, and adapted to house a shaft of the apparatus downstream of the kinematic mechanism; - a measuring device (15) for measuring the angular speed of the rotating shaft (5), suitable for providing a signal of intervention of the braking effect in the event that the angular speed exceeds a threshold; - a fixing element (2) for fixing the brake to said kinematic mechanism; - a containment box (1) adapted to enclose said brake, said containment box ending on one side with said fixing element (2) and on the other side with said magnet (3), and being crossed by said rotating shaft (5).</p>
