Mazda CX-5 Service & Repair Manual: Power Window Motor

Purpose

The power window motor transmits rotation force to the power window regulator to open/close the door glass.

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 parts:

• Motor

• Connector

• Gear

• Two Hall effect switches are located in the driver's side connector.

• The Hall effect switches output pulse to the P/W CM.

  

  
  

Operation

• The Hall effect switch utilizes magnets set on a rotating axis to detect the motor rotation, and outputs a synchronized pulse to the P/W CM.

• The Hall effect switch 1 outputs one pulse cycle for each rotation of the power window motor axle, and the P/W CM detects motor rotation speed.

• Hall effect switch 2 outputs pulse according to the 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.

  

  
  

Fail-safe

• Function not equipped
