Large-diameter window motor structure

[Arthurs]

Hi everyone:
This is just one idea,
Performance window motor is very superior,If will window motor diameter increases,Rotor diameter increases,Can make driving less power,And large-diameter rotors,Since the flywheel effect can give good inertia,Can better improve window motor efficiency.

Welcome your comments and opinions,thanks

大家好：
这只是一个想法，
性能窗电机是非常出众的，如果将车窗电机直径增大，转子直径增大，可以使驾驶更省电，和大直径转子，由于飞轮效应能提供良好的惯性，可以更好地提高窗口电动机的效率。

A magnet which is all South, or a magnet which is all North, does not exist. This would be a monopol, which has not been discovered yet.

" --- Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles, and in fact there is no conclusive experimental evidence that magnetic monopoles exist at all in the universe.    --- "

In your drawings each magnet should have a North and a South pole. And the coil should be near the North or the South pole of a bar magnet, not near both poles at the same time.

The coil and magnet position and orientation are correct. This is the most efficient way to build a window motor. Although depicted wrong,that magnet orientation is quite possable. You would need long bar magnets that join via a steel bearing housing in the center of the rotor.

In the picture with the coil, The left is seeing a south pole , the right is seeing north.
Would it not be better for the coil to see the same pole on the front of the rotor (the side we can see) and the opposite pole on the back (the side we don't see)?
To me that would just cause cancelation .
