Abstract:
Lifting/swiveling drive having a working element (2) which can move rotatably and linearly relative to a housing element (1), characterized in that in order for the working element (2) to move in a controllable, linear and rotative, contactless manner relative to the housing element (1) and in order to measure and/or control a linear movement of a linear motor (5), rotative movement of the working element (2) takes place by means of a rotatively decoupled and linearly coupled measuring device (10), the measuring device being coupled linearly to the linear movement of the working element (2), and characterized in that by rotatively decoupling the measuring device (10) relative to the rotatively and linearly movable working element (2), a permanent, contactless measurement of the rotational movement is ensured by means of rotation sensors (17, 18) which lie opposite each other and spaced apart in a contactless manner between the measuring device (10) and working element (2).
