  • Publication number: 20240102787
    Abstract: An inductive position-measuring device includes a scanning element and a graduation element movable relative thereto along a direction. The scanning element has an excitation conductor, and first and second receiver tracks each having a receiver conductor, which extends along the direction according to first and second periodic patterns, respectively, over a length. A graduation track has graduation structures formed of ridges and gaps. The ridges have different widths, or the gaps have different depths or different widths, in the direction. The receiver conductors of the first and second receiver tracks are configured to generate first and second signals having first and second period lengths, respectively, wherein n times the first period length equals m times the second period length, with m and n being relatively prime, and n times the first period length and m times the second period length both being less than or equal to the length.

  • Patent number: 11933643
    Abstract: An inductive angle measuring device includes a scanning element and a scale element having scale tracks. First and third scale tracks have an equal first number of scale structures, and a second scale track has a different number of scale structures. The scale tracks are arranged circumferentially and concentrically about an axis, such that the first scale track is located radially inwardly, the second scale track is located radially between the first scale track and the third scale track, and the third scale track is located radially outwardly. The scanning element includes receiver conductors by which the signals having angle-related signal periods can be generated. The first signal period is equal to the third signal period. An overall signal can be generated from the first signal and the third signal and can be combined with the second signal for determining absolute angle position information.

  • Patent number: 11841248
    Abstract: A scanning element includes a circuit board having a first detector unit provided with a first receiver conductor trace arranged circumferentially about an axis in the circumferential direction. The course of the first receiver conductor trace has: a periodic configuration along a first line; a first gap along its extension in the circumferential direction; a first amplitude in the first quadrant or in the second quadrant of a Cartesian coordinate system; and a second amplitude in the third quadrant or in the fourth quadrant of the coordinate system. The origin of the coordinate system is located on the axis, and the ordinate extends centrically through the first gap in relation to the circumferential direction. The second amplitude is smaller than the first amplitude.

  • Patent number: 9383184
    Abstract: An inductive position-measuring device includes a scanning element and a graduation element that are movable relative to each other in a first direction. The scanning element includes exciter conductors and three receiver tracks. The first and the second receiver track are disposed at a distance relative to each other, and the third receiver track is located between the first and the second receiver track. The graduation element includes two graduation tracks which are disposed at a distance relative to each other, and which have different graduation periods. Furthermore, electromagnetic fields generated by the exciter conductors are able to be modulated by the graduation tracks, so that a relative position in the first direction is detectable by the first and the second receiver track, while a relative position in a second direction, which is oriented orthogonally with respect to the first direction, is detectable by the third receiver track.
