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.
