Power Window Motors

Power Window Motors





The drive mechanism of a power window lift is a cable lift mechanism consisting of:
^ A DC motor
^ A reduction gear with incremental sensor (Hall sensor)
^ Evaluation Circuit
^ A shrouded connection
The drive mechanism incorporates two Hall sensors, which are addressed by a magnet wheel mounted on the armature shaft.
The two Hall sensors and the magnet wheel determine with the aid of the door module or the KBM the direction of rotation, the speed and the position of the window.
