摘要:
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.
