The drive has a switch wheel (1) driven by the elastic motor, carrying permanent magnet markings (6,7) in defined positions. A respective Hall (HS1,...HS3) is associated with each marking, to provide signals representing the position of the drive, used by an electronic operating control for the electric drive motor. Pref. the Hall sensors are enclosed by the field of the respective permanent magnet markings on 2 sides, each of the markings positioned at a respective switch wheel radius. <IMAGE> |
