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.

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 component parts.

― Motor

― Connector

― Gear

• The power window motor has two Hall effect switches.

― 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

• 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.
