  • Flexible printed circuit magnetic flux probe
    Patent number: 6466009
    Abstract: A flexible probe is provided for detecting time-varying magnetic fields produced in an electric generator. The flexible probe is adapted to be disposed within an air gap formed between an iron stator and a rotatable rotor. An electrostatic shield layer is formed on a front face of the probe and a printed circuit forming at least one coil is printed on the back face. When the flexible probe is used for detecting time-varying magnetic fields, a voltage is induced in the coil when the coil is exposed to a time-varying magnetic field.
