  • Inductive position measuring device
    Patent number: 10989515
    Abstract: An inductive position-measuring device includes a scanning element and a graduation element, rotatable about an axis relative to the scanning element. The scanning element has exciter lead(s), a first receiver track, including receiver line(s), extending according to a first periodic pattern having a first period along a first direction, and a second receiver track, including receiver line(s). The graduation element includes a graduation track, extending in the circumferential direction and including a graduation period. An electromagnetic field generated by the exciter lead(s) with the aid of the graduation track is able to be modulated, so that an angular position is detectable with the aid of the receiver line of the first receiver track, and a position of the graduation element in the first direction relative to the scanning element is detectable with the aid of the receiver line of the second receiver track.
