Abstract
An electromagnetic brake system is disclosed for controlling motion of a component that is movable relative to the brake system. The system includes a magnet body mounted to a support and having at least one electrically controlled magnetic device on it for generating a magnetic force when activated. A back plate is mounted adjacent to the magnet body on one side of a movable component. An armature plate is located between the magnet body and the movable component. At least one spring is located on the magnet body between the magnet body and the armature plate for biasing the armature plate away from the magnet body. The spring has a spring force that is less than the magnetic force of the magnetic device such that activation of the magnetic device urges the armature plate toward the magnet body, overcoming the spring force.
