Embodiment Construction

[0033] Embodiments are explained in more detail below with reference to the drawings, in which elements having the same or similar functions are provided with the same reference numerals.

[0034] If k-fold symmetry is mentioned here, this is to be understood as a form of rotational symmetry or rotational symmetry. An object has k-fold symmetry if it can be rotated 360°*n / k around the axis so that the object looks the same after rotation as it did before rotation (where n is any integer (Integer)). Also, in this disclosure, k-fold symmetry is characterized in that in case of k-fold symmetry, if the coil (or target) is rotated 360° / k, the signal induced in the coil (or target) remains same.

[0035] If values ​​for angles are specified herein, these also apply within a tolerance of ±10% or ±1°. This means that even if the angles mentioned herein have deviations in the range of ±10% or ±1°, the innovative concept described herein can still provide satisfactory results.

Abstract

The embodiments of the invention relate to an inductive angle sensor having two pickup coil arrangements arranged offset form. The innovative concept described herein relates to an inductive angle sensor. The 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 alpha 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 rho.

Description

technical field [0001] The innovative concept described herein relates to an inductive angle sensor and in particular to an inductive angle sensor with integrated compensation of the system error band when determining the rotation angle between the stator and the rotor. For this purpose, the inductive angle sensor has a stator with a first pickup coil arrangement and a substantially identical second pickup coil arrangement, wherein the two pickup coil arrangements are offset relative to each other by a defined angle of rotation be furnished. Background technique [0002] Inductive angle sensors typically have a stator and a rotor that can rotate relative to the stator. In order that the rotor can rotate relative to the stator, there is a slight air gap (the so-called airgap) between the rotor and the stator. The stator can be implemented, for example, as a printed circuit board, abbreviated as PCB (English: Printed Circuit Board). Field coils can be arranged on the stator...
