A power window motor is a car window that is raised and lowered by a motor which is controlled by means of a switch. . When the switch is activated it completes a circuit, sending electricity to the motor which then moves the window up or down. Many power windows have a variety of added features such as one-touch opening, lockout switches, and courtesy power on.
Operation: The Lifting Mechanism is a device that plays important role in power window system. The process of lifting windows in most cars uses a really neat linkage to lift the window glass while keeping it level. A small electric motor is attached to a worm gear and several other spur gears to create a large gear reduction, giving it enough torque to lift the window. An important feature of power windows is that they cannot be forced open - the worm gear in the drive mechanism takes care of this. Many worm gears have a self-locking feature because of the angle of contact between the worm and the gear. The worm can spin the gear, but the gear cannot spin the worm friction between the teeth causes the gears to bind.
