Inductive position-measuring device

摘要

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.

主权项

1. An inductive position-measuring device, comprising:
a scanning element; and a graduation element, the scanning element and the graduation element movable relative to each other in a first direction; wherein the scanning element includes exciter conductors and three receiver tracks, each receiver track having at least one receiver conductor, a first receiver track and a second receiver track arranged relative to each other at a distance that extends orthogonally with respect to the first direction, a third receiver track located between the first receiver track and the second receiver track; wherein the graduation element including two graduation tracks arranged relative to each other at a distance that extends orthogonally with respect to the first direction, and that have different graduation periods along the first direction; wherein the graduation tracks are adapted to modulate electromagnetic fields generated by the exciter conductors, a relative position in the first direction detectable by the receiver conductors of the first receiver track and the second receiver track, and a relative position in a second direction that is oriented orthogonally with respect to the first direction detectable by the at least one receiver conductor of the third receiver track.
