  • Electromagnetic moving-coil device
    Patent number: 6836032
    Abstract: The electromagnetic moving-coil device in which a position coil is provided to function as a secondary coil in accordance with the principles of a linear variable differential transformer so that when a high-frequency excitation signal is superimposed upon the driver signal applied to the moving coil, a position coil picks up the position of the moving coil and allows that position to be computed or displayed.
