Electromotive auxiliary drive e.g. windshield wiper drive, for e.g. road vehicle, has permanent magnet provided at shaft extension or at gearing unit, and magnetic sensors provided within bearing arrangement toward shaft axis

摘要

The drive has magnetic sensors (15, 16) cooperating with a signal generator and a permanent magnet for detecting angle position and/or change of the angle position of rotating movement of a shaft or a gearing wheel. The permanent magnet is provided at a shaft extension supported in a bearing arrangement (7) or at a gearing unit supported in the bearing arrangement and provided in the shaft (5). The magnetic sensors are provided within the bearing arrangement towards a shaft axis (5.1).
