Abstract

PURPOSE: To completely eliminate the effect of internal error magnetic field, with the adjustment of the input current to two sets of coils wound on the external side of the angle sensor.
CONSTITUTION: The DC currents Iy and Ix are respectively fed to the compensation coils 4 and 5 wound orthogonally via the resistors 8 and 9 from the variable DC power supplies 6 and 7. The internal error magnetic field is cancelled with the magnetic field produced with the compensation coils 4 and 5, and the measuring error is eliminated with the internal error magnetic field from the result. As the magnetic detector, the Hall element and modulation type magnetic detector are used.
