    摘要： The present invention relates to an electric linear drive, particularly for a rotary-lifting motor. Such a linear drive includes a winding system including a plurality of wound coils which are arranged to be coaxial to each other and successive in axial direction, and a magnet system which is movable in axial direction relative to the winding system and includes a plurality of axially successive permanent magnets. The winding system is normally fed by a controlled converter. The coils of the winding system and the permanent magnets of the magnet system define an air gap thereinbetween. Furthermore, a sensor is provided for detecting the relative movement of winding system and magnet system and for detecting the relative position of the two systems, the sensor being used for scanning a timing ruler mounted on the outer circumference of the magnet system. The magnet system is radially arranged in the interior of the winding system, and the timing ruler circumferentially extends only over a portion of the circumference of the magnet system. According to the invention it is either provided that the coils of the winding system have a radial bulge for the timing ruler, or that the magnet system is eccentrically arranged relative to the winding system, or that the magnet system includes a radial bulge in the form of a flat portion for the timing ruler.
