Abstract

The aim of the invention is to provide a linear/rotation drive with an improved transmitter device for detecting the linear and rotational movements. For this purpose, the transmitter device (12, 14, 16, 17) for detecting the linear movement and/or rotational movement of the secondary part (4) of the linear drive (2) configured as an external rotor is at least partially arranged inside the primary part (6) of the linear drive (2). In this manner, the transmitter device (12, 14, 16, 17) is located in a magnetically shielded area. In order to avoid eccentricities in the transmitted device (12, 14, 16, 17), a journal (10) of the secondary part (4) is mounted on a bearing (11) in the primary part (6).
