Abstract
A magnetic rotational angle transducer has at least one Hall sensor () rotatable in a magnetic field of a given configuration relative to and offset from the rotational axis (). To enable linearization of the output signal without additional signal processing over a large range of rotational angles, it is proposed that the Hall sensor is aligned radially and axially to the rotational axis () and lies in a central position parallel to the field lines of the magnetic field, wherein the magnetic field is created by at least one permanent magnet () in circular segment form around the rotation axis and the Hall sensor () is offset from the rotational axis () towards the permanent magnet () in circular segment form.
