Abstract
An inductive angle sensor includes an inductive target arrangement with k-fold symmetry and a first pickup coil arrangement with k-fold symmetry and a second pickup coil arrangement with k-fold symmetry. A combination apparatus is designed to combine signals of the first pickup coil arrangement with signals of the second pickup coil arrangement and, on the basis thereof, to ascertain an angle-error-compensated rotation angle. The single pickup coils of the first and second pickup coil arrangements are each rotationally offset about the axis of rotation R by a geometric offset angle α relative to one another. Additionally, the entire first pickup coil arrangement is rotationally offset relative to the entire second pickup coil arrangement about the axis of rotation R by a geometric offset angle ρ.
