Abstract
A detection device for a position sensor and to a detection system comprising such a detection device. The detection device comprises, in some embodiments, at least one primary winding and a secondary winding circuit. The secondary winding circuit has a plurality of secondary windings which are inductively coupled to the at least one primary winding during operation of the detection device, and the plurality of secondary windings is designed as two sinusoidal coils, each having a center tap.

A detection device for a position sensor, comprising:
- a primary winding;
- and
- a secondary winding circuit having a plurality of secondary windings inductively coupled to the primary winding during operation of the detection device;
- wherein the plurality of secondary windings is formed as two sinusoidal coils routed in an overlapping arrangement, each having a center tap provided as a vertical contact of a printed circuit board, and wherein the detection device is configured, for each sinusoidal coil, to tap voltage signals of both half-coils using the center tap as a common node together with, respectively, a first end terminal and a second end terminal of that sinusoidal coil.
A detection device for a position sensor, comprising:
- a primary winding;
- and
- a secondary winding circuit having a plurality of secondary windings inductively coupled to the at least one primary winding during operation of the detection device;
- wherein the plurality of secondary windings comprises a first subset of at least two secondary windings and a second subset of at least two secondary windings arranged in series with each other;
- and
- wherein the secondary winding circuit further comprises a first resistor or capacitor arranged between a secondary winding from the first subset and a secondary winding from the second subset or arranged in parallel with a first secondary winding from the first subset or the second subset;
- wherein the plurality of secondary windings is formed as two sinusoidal coils routed in an overlapping arrangement, each having a center tap provided as a vertical contact of a printed circuit board, and wherein the detection device is configured, for each sinusoidal coil, to tap voltage signals of both half-coils using the center tap as a common node together with, respectively, a first end terminal and a second end terminal of that sinusoidal coil, and
- wherein only one primary winding is provided, which is formed as a rectangular coil and surrounds the secondary windings in plan view.
