POSITION DETECTION DEVICE AND A DRIVE DEVICE

摘要

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. The detecting modules are configured to output a position signal when detecting the movable element, so that during a shift of the movable element along the two detecting modules over the predefined distance this distance may be measured as a reference distance on the basis of the position signals.
