8.2.15.2. The window regulator electric motor with the servo-driver

Design and work principle.

The window regulator electric motor with the servo-driver is equipped with the socket and a gear wheel.

Two contactless switches on the sensor of the Hall are established in the socket.

The contactless switch on the sensor of the Hall uses a set of magnets on a rotating axis for data acquisition about rotation of the electric motor of a window regulator with the servo-driver and deduces the synchronized impulse to the main switch of a window regulator.

The contactless switch on the sensor of the Hall No. 1 gives out one impulse at each turn of an axis of the electric motor of a window regulator. Respectively, the main switch of a window regulator defines angular speed of rotation of the electric motor.

Fig. 8.32. The window regulator electric motor with the servo-driver: 1–electric motor; 2–socket; 3–gear wheel; 4–the contactless switch on the Hall No. 1 sensor; 5–the contactless switch on the Hall No. 2 sensor; 6–shaft; 7–magnet; 8–low; 9–highly; 10-an impulse (the contactless switch on the Hall No. 1 sensor); 11-an impulse (the contactless switch on the Hall No. 2 sensor); 12-one turn of the electric motor of a window regulator with the servo-driver; 13-detection of distance of moving of glass; 14-up; 15-down; 16-detection of the direction of moving of glass

The main switch determines the direction of rotation of the electric motor of a window regulator by a difference between the highest and lowest points of an impulse from each contactless switch on Hall No. 1 and 2 sensors.
