Abstract: An electronic safety actuator assembly for an elevator system includes a safety case vertically moveable relative to an elevator car. Also included is a safety brake disposed within the safety case. Further included is an electromagnet operatively coupleable to the elevator car. Yet further included is a link member operatively coupleable to the elevator car and to the safety brake. Also included is a magnet disposed between the electromagnet and the safety case, the magnet vertically moveable relative to the elevator car, the electromagnet switchable between an energized condition and an un-energized condition, one of the energized condition and the un-energized condition magnetically attracting the magnet to the electromagnet, the other of the energized condition and the un-energized condition magnetically repulsing the magnet away from the electromagnet, repulsion of the magnet moving the safety brake from a non-braking position to a braking position.

Abstract: An example elevator brake includes a first braking member that is biased by a first spring member into engagement with a braking surface. The first braking member includes a first armature arranged to be actuated by an electromagnetic actuator to disengage the first braking member from the braking surface against the biasing force of the first spring member. A second braking member is biased by a second spring member into engagement with a braking surface. The second braking member includes a second armature arranged to be actuated by an electromagnetic actuator to disengage the second braking member against the biasing force of the second spring member. A first electromagnetic actuator actuates the first armature and a second electromagnetic actuator actuates the second armature.

Abstract: An elevator system (10) is comprised of a car (22), and a shaft (46) operatively connected to the car and configured to rotate for movement of the car through the elevator system. A brake assembly (44) is comprised of a disk (56) connected to and configured to rotate along with the shaft. Movable plates (60, 62) are placed on respective opposite sides of the disk and configured to move axially toward and away from the disk. Electromagnets are configured to respectively move the movable plates away from the disk. Elastic elements (64, 66) are configured to respectively move the movable plates toward the disk. The disk is free to move axially, and is designed to stop the movement of the car by stopping the rotation of the shaft when the rotation of the disk is stopped by friction from contact of the movable plates with the disk when the elastic elements move the movable plates toward the disk.
