Abstract:
An actuator assembly for an elevator governor system includes a governor for detecting an overspeed condition. Also included is a safety linkage actuating lever operatively coupled to the governor. Further included is at least one safety operatively coupled to the safety linkage actuating lever and configured to apply a braking force during an overspeed condition. Yet further included is a permanent magnet latch engaged with the safety linkage actuating lever, the permanent magnet latch preventing actuation of the safety by the safety linkage actuating lever during a normal speed condition. Also included is an electromagnetic component disposed proximate the safety linkage actuating lever and the permanent magnet latch and in operative communication with the governor, the electromagnetic component in an energized condition during the overspeed condition to overcome a force applied by the permanent magnet latch to the safety linkage actuating lever to actuate the safety.
