Motor, Electrically Operated Window Lift, Driver (164D)





Main purpose
Raise and lower the door window. Indicate the position of the motor (variants with pinch protection).

Type
The electric window motor contains a 2-pole motor and worm gear. The polarity of the motor is reversed to run it in the opposite direction. In variants with pinch protection, the motor also has 2 Hall sensors that indicate the position of the motor. The Hall sensors are mounted by the motor shaft 90 degree from each other. The motor shaft has a 2-pole rotor.

Connection

Electric motor
The motor is connected with 2 wires to the door control module. (DDM)

Hall sensors
The sensors are connected by 4 wires to the door control module. The sensors have a common 4.7 V power supply and common ground. 2 signal wires supply each sensor with B+ via an integrated resistor. When the South pole of the magnet passes the sensor, the sensor shorts the B+ feed to ground.

The control module inputs are digital. A voltage greater than 2 V is regarded as "OFF" and lower than 2 V as "ON". The control module calculates the position of the window by counting the number of changes between "ON" and "OFF". The control module will count 2 changes per revolution of the motor from each Hall sensor. Since the sensors are displaced by 90 degree, the control module will detect a total of 4 changes, displaced by 90 degree, each revolution.
