  • System and method for measuring dynamic loads in a magnetic bearing
    Patent number: 6518770
    Abstract: A system for measuring dynamic loads in a rotordynamic system having a rotor includes a magnetic bearing disposed around the rotor and having a plurality of magnets and at least one fiber optic strain gage associated with a pole of a respective magnet. The fiber optic strain gage is operable to detect a strain on the respective pole resulting from the dynamic loads. The detected strain is indicative of the dynamic loads.
