POWER WINDOW MOTOR
id091200012400
Purpose
• The power window motor transmits rotation force to the power window regulator.
• The power window motor outputs pulse to the power window control module to input motor operation status. (With auto-open/close function)
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.
Structure/Construction
• The power window motor consists of the following parts:
-
― Motor
― Connector
― Gear
• The power window motor has two Hall effect switches. (With auto-open/close function)
-
― The Hall effect switches output pulse to the power window control module.
Operation
Open operation
-
• When the power window motor receives an open signal from the power window main switch or power window subswitch, the motor rotates counterclockwise.
Close operation
-
• When the power window motor receives a close signal from the power window main switch or power window subswitch, the motor rotates clockwise.
Hall effect switch operation (With auto-open/close function)
-
• The Hall effect switch utilizes magnets set on a rotating axis to detect the motor rotation, and outputs one pulse cycle for each rotation of the motor rotation axis.
• 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
approx. 90°.
Fail-safe
• When the power window motor is operated continuously for a certain period of time, the power window motor operation is stopped temporarily to protect the power window motor inner circuit.
