Patent ID: 8384376

Claim:
A multi-turn angle sensor, said sensor comprising: a. at least one encoder magnet ( 1 ) having a mechanical drive, rotatably supported about a rotation axis ( 2 ); b. a magneto sensitive sensor unit ( 4 ) with a sensor element ( 5 ), which is permeated by the magnetic field of the encoder magnet ( 1 ); c. on the one hand, detecting and putting out the rotation angle of the pole direction of the encoder magnet ( 1 ) about the rotation axis ( 2 ); d. on the other hand, detecting and putting out the absolute value of the magnetic field applied to the sensor element ( 5 ) of the sensor unit ( 4 ); wherein e. the axial distance between the at least one encoder magnet ( 1 ) and the sensor element ( 5 ) is constant; and f. an additional field variator ( 6 ) which changes the magnetic field provided at the sensor element ( 5 ) as a function of the total rotation angle of the encoder magnet ( 1 ) and wherein the additional field variator ( 6 ) is moved by means of a threaded spindle, on which a spindle nut runs.
