Motor, Electrically Operated Window Lift, Front (164FL/FR)
Location
Main task
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
degrees from each other. The motor shaft has a 2-pole rotor.
Connect
Electric motor
The motor is connected with 2 wires to the door control module. (DDM)
Hall sensor
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.
