Abstract:
A position detection device for detecting a position of a movable element in a drive device comprises a carrier having two detecting modules for detecting a position of the movable element, the detecting modules being arranged side-by-side at a predetermined distance and without overlapping. Each detecting module comprises an energizing coil and a receiving coil assigned to the energizing coil and comprising a geometry having one period.
