Meetech Industries make Electromagnetic brakes are used in conjunction with other equipments where smooth, rapid and dependable stopping is required. Electromagnetic DBM brakes are electrically released & spring set. When the coil is energized the armature are attracted together to compress the torque spring and move the shoes away from the wheel, thus releasing the brake. De-energizing the coil allows the torque spring to separate the armatures and press the shoes against the wheel setting the brakes thus making it fail safe in the event of power failure.
