  • Overload protection system for an electromagnetic lift
    Patent number: 7564662
    Abstract: A method for protecting against current overload conditions associated with an electromagnetic lift system comprises receiving current data from a current monitoring device associated with an electromagnetic lift system. The method also includes determining a current level based on the collected current data, and identifying a predetermined overload range corresponding to the current level if the current level exceeds an overload current threshold. The method also includes monitoring a time that the current level is within the predetermined overload range, and providing a command signal to an actuator associated with the electromagnetic lift system if the time that the current level is within the predetermined overload range exceeds a predetermined time limit. The command signal causes the actuator to substantially limit mechanical power provided to a generator associated with the electromagnetic lift system.
