Patent ID: 7259554

Claim:
An angle position sensor for detection of an angle position of a component which can rotate about a rotation axis comprising: a magnet ring connected in a rotationally fixed manner to the component, coaxially with respect to the rotation axis, and magnetized transversely with respect to the rotation axis; a ferromagnetic outer shielding ring surrounding an external circumference of the magnetic ring; a magnetic sensor element which is arranged in a fixed position radially within the magnet ring; a ferromagnetic inner shielding ring which is arranged coaxially with respect to the rotation axis and approximately radially with respect to the outer shielding ring, wherein the inner shielding ring surrounds the component; and an inner magnet ring arranged so as to surround the inner shielding ring, wherein the inner magnet ring and the inner shielding ring are connected in a rotationally fixed manner to the component which can rotate, wherein the magnetic sensor element is arranged in an annular gap which is formed between the outer magnet ring and the inner magnet ring, wherein magnetization of the inner magnet ring which opposes the magnetization of the outer magnet ring and being designed such that a magnetic flux density at a location of the inner shielding ring corresponds approximately to a magnetic flux density when no inner shielding ring is present.
