When turning, magnetic field and the overlapping area of coil that magnetic steel rotor 1 generates can change, so as to directly affect magnetic fields area
Size, and then cause the variation of induced electromotive force size；By external equipment measure induced electromotive force virtual value, and by its with
Deflection angle is mapped, it is possible to the curve that induced electromotive force changes with deflection angle is obtained, it is inclined so as to obtain magnetic steel rotor 1
The angle turned.Therefore, which is converted into electric signal using electromagnetic induction principle by measured Angle Position, it is not required to
