POWER WINDOW MOTOR CONSTRUCTION
id091200101400
• Consists of a motor, connector, gear, and two hall effect switches.
• 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 switch.
• Hall effect switch 1 outputs one pulse cycle for each rotation of the power window motor axle and the power window switch detects motor rotation speed from this.
• Hall effect switch 2 detects motor rotation in the same manner as Hall effect switch 1. Due to this, the high and low pulse points of Hall effect switches 1 and 2 are different during opening and closing allowing the power window main switch to detect the rotational direction of the power window motor.
