Inductive detection of a rotational angle

A sensor assembly for detecting a rotational angle of at least one flux element comprising:

• the at least one flux element;
• and
• at least one coil group comprising at least one flat coil;
• wherein the at least one flat coil extends along a face which concentrically surrounds the rotation axis;
• wherein the face runs in parallel along the circular path, and all of the at least one flat coil of the at least one coil group each extend across the same rotational angular range;
• wherein the at least one flat coil is shaped in such a manner that a current inductance of the at least one flat coil is a function of the current rotational angle of the at least one flux element;
• wherein the sensor assembly further comprises an evaluation installation configured to determine the current inductance for each of the at least one flat coil and to determine a current respective individual rotational angle of the at least one flux element by means of the determined inductance of each of the respective at least one flat coil, and to provide the rotational angle of the at least one flux element based on at least two matching individual rotational angles.
