  • Electromechanical drive for magnetometers
    Patent number: 6630825
    Abstract: A vibrating sample magnetometer controls an electromechanical drive using both ac and dc control and a position sensor. Absolute position sensing is used in a feedback loop to control both an alternating current (ac) drive and a direct current (dc) drive to the electromechanical drive. Improved performance and stability results.
    Type: Grant
