So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

The Overall Functionality Of Power Window Motors

By Ann Baker


Various advancements have been evidenced in the automobile community where massive automation has been realized for purposes of fostering the overall comfort of the car owners. The concrete feature that has been recently achieved is the installation of the power window motors on car windows. They are operated by switches which are strategically placed on the doors. The ultimate goal of this motor is to initiate the opening and closing of the window glasses.

The optimal operation of a system is necessitated by the attachment of a worm gear which is a lengthy metallic bar with one end spiral-shaped just like a screw. The gear is teeth-like along its circumference. Thus, the gear moves the circular gear by connecting the teeth embedded inside a spiral which is then connected with other spur gears. These special gears are purposely for gear reductions. Therefore, the community of gears provides the torque needed to open or close the car windows.

The bars that hold the glasses are strategically placed together with other metallic plates which fall and rise like a pivoted beam. The rotation of gears moves the arms thus lowering or raising the glass windows. As one arm rises, the other one counteracts it but moving upwards as the gears rotate. They are set such that if the major arm is pulled up on a right side, the other arm may be lifted on the other side thus confirming that a glass rise and also falls evenly.

The motor is responsible for turning all those gears, unlike the crank handle that is used in manual windows. It sources its mechanical and kinetic energy from the car battery which sends it to the power distribution box. As the flip is pressed, the fused wire transmits current to the motor thus initiating the operation. This is achieved as the switch simultaneously works by closing and opening two distinct circuits which are connected to the motor.

The lifting mechanism is enhanced by the automated switch button on a side of a chauffeur. On pressing the button, the glass will laterally move in a horizontal or a vertical direction depending on the magnitude you press it. The pressing process triggers the motor to move continuously thus initiating the overall up and down movement of this glass windows. Nevertheless, some car models do not pose this automatic feature due to safety purposes thus when obstructed they simply halt.

The electric nature of motors facilitates the functionality of a regulator. It is responsible for various essential functions which allow opening and closing of the glasses and also for security purposes. They include the normal manual opening and closing and keying-off power functions. Similarly, it is also responsible for the security function by its window locking feature. It, therefore, gains the requisite power from the rotating motor.

In addition, they also require regular maintenance to ascertain their efficiency in operation. Therefore, they demand an immediate restitution once they become faulty. This is because they are so vital to the overall functionality of a car. Thus, they oblige for total replacement rather than merely repairing them which might cost more.

Finally, the devices are the core components in opening and closing of such glass windows. However, their overall functionality depends on other components like the regulator, the electrical connection circuitry, and the battery of a vehicle.
