POWER WINDOW MOTOR CONSTRUCTION

BHE091258000T05

## Structure and Operation

• The power window motor consists of a motor, connector and gear.

• Two Hall effect switches are set in the connector.

• The Hall effect switch utilizes magnets set on a rotating axis to sense the power window motor rotation, and outputs a synchronized pulse to the power window main switch.

• Hall effect switch No. 1 outputs one pulse cycle for each rotation of the power window motor axle. Accordingly, the power window main switch detects the rotational speed of the power window motor.

• The power window main switch detects the rotational direction of the power window motor by the difference between high and low pulse points from Hall effect switch No. 1 and 2.
