POWER WINDOW MOTOR
id091200012400
Purpose
The power window motor transmits rotation force to the power window regulator to open/close the door glass.
Function
The power window motor rotates clockwise/counterclockwise when it receives an open/close signal from the power window main switch or the power window subswitch.
Construction
• The power window motor consists of the following parts:
-
― Motor
― Connector
― Gear
• Two Hall effect switches are located in the driver's side connector.
-
― The Hall effect switches output pulse to the power window control module.
Operation
• The Hall effect switch utilizes magnets set on a rotating axis to detect the motor rotation, and outputs a synchronized pulse to the power window control module.
• The Hall effect switch 1 outputs one pulse cycle for each rotation of the power window motor axle, and the power window control module detects motor rotation speed.
• Hall effect switch 2 outputs pulse according to the motor rotation in the same manner as Hall effect switch 1. The high and low pulse points of Hall effect switches 1 and 2 are different during opening and closing because the phase difference shifts by 90°, allowing the power window main switch to detect the rotational direction of the power window motor.
Fail-safe
• Function not equipped.
