Claims
- 1. An inductive angle-of-rotation sensor, comprising:
a printed-circuit board, an excitation printed conductor and at least one receiving printed conductor arranged on the printed-circuit board, the at least one receiving printed conductor including a first partial section, which extends in a first plane, and a second partial section, which extends in a second plane; and a graduation element rotatable in relation to the printed-circuit board, the graduation element including a graduation track, the graduation track including alternately arranged, electrically conductive and non-conductive graduation regions; wherein the at least one receiving printed conductor is configured to supply an uneven number of signal periods within one rotation relatively to the graduation element; and wherein the first partial section of the at least one receiving printed conductor is substantially greater in length than the second partial section.
- 2. The inductive angle-of-rotation sensor according to claim 1, wherein the length of the first partial section of the receiving printed conductor is at least 1.5 times a length of the second partial section.
- 3. The inductive angle-of-rotation sensor according to claim 1, wherein the length of the first partial section of the receiving printed conductor is at least 3 times a length of the second partial section.
- 4. The inductive angle-of-rotation sensor according to claim 1, wherein a plurality of receiving printed conductors are arranged on the printed-circuit board, each receiving printed conductor having a respective first partial section extending in a first plane and a respective second partial section extending in a second plane, the first partial sections extending in the same plane.
- 5. The inductive angle-of-rotation sensor according to claim 1, wherein the at least one receiving printed conductor is configured to supply one signal period within one rotation relatively to the graduation element.
- 6. The inductive angle-of-rotation sensor according to claim 1, wherein the printed-circuit board includes a multilayer structure, the first and second partial sections of the at least one receiving printed conductor arranged on different sides of a non-conductive layer.
- 7. The inductive angle-of-rotation sensor according to claim 1, wherein the first plane is arranged in closer proximity to the graduation element than the second plane.
- 8. A rotary transducer, comprising:
an inductive angle-of-rotation sensor, the inductive angle-of-rotation sensor including:
a printed-circuit board, an excitation printed conductor and at least one receiving printed conductor arranged on the printed-circuit board, the at least one receiving printed conductor including a first partial section, which extends in a first plane, and a second partial section, which extends in a second plane; and a graduation element rotatable in relation to the printed-circuit board, the graduation element including a graduation track, the graduation track including alternately arranged, electrically conductive and non-conductive graduation regions; wherein the at least one receiving printed conductor is configured to supply an uneven number of signal periods within one rotation relatively to the graduation element; and wherein the first partial section of the at least one receiving printed conductor is substantially greater in length than the second partial section.
- 9. The rotary transducer according to claim 8, wherein the first plane is arranged in closer proximity to the graduation element than the second plane.
