  • Radial air-core gauge
    Patent number: 5038099
    Abstract: A radial type air-core gauge includes orthogonally positioned pairs of stator coils wound on independent coil forms spaced radially 90 degrees apart about a central cup of a gauge case. The cup houses a permanent magnet rotor which rotates about a shaft extending from a support bearing in a bottom surface of the cup to a hub of a dial pointer. Movement of the shaft causes a dial pointer to move over a dial face in response to changes of a balanced resultant field caused by variations of excitation signals applied to the stator coils.
