POWER WINDOW MOTOR CONSTRUCTION

id091200006900

• Consists of a motor, connector, and gear.
• Two Hall effect switches are located in the connector.
• 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 main switch.
• Hall effect switch 1 outputs one pulse cycle for each rotation of the power window motor axle and the power window main switch detects motor rotation speed from this.
• Hall effect switch 2 outputs pulse corresponding to 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.
