Magnetic Door by John Bédini

[yanyan26]

Hello

Looking at your animated imaje I imagined, but this is only an idea:

If your rotor magnet had a conical shape (surely not easy to find magnets like that), the magnetic fields which are, I think opposite to the entry of the doors, would meet less contrary fields ???

Maybe ???

Courage and good luck

Probably yes, but did you say where to find a conical magnet? !!

[yanyan26]

I also thought that:

If the magnets of the doors were hinged and the field of the rotor makes them return a little, pressing a small spring which would put them back in position at the time of the push

Basically, the door magnets would enter when the rotor enters, so less resistance.
But hey I see it in my head and I know it's a very big project

Better to cut a cone-shaped magnet

Bof mode:

Great ! It must be…

an e-cone-at-the-logis-point-con


And, mounted on springs, please!

Excellent E-cone Gegyx,

As for moving door magnets yanyan26, it touched my mind too.
I thought about the problem the name of the page is "dynamic door" !!
It is also true that it is a reel not easy to set up because the mechanisms will have to be very small !!

But hey we can always think and throw it on paper it frees up.

A + + +

Hi everybody

I think it is easier to tilt the magnets of the doors (as on the model of the first pages) than to find a conical diver ??? no???
That way the resistance at the exit could be reduced
or maybe better the magnets of the doors positioned in the shape of V. Like that the efforts of repulsion at the entry and at the exit decrease but one keeps the phase of acceleration when the plunger is returned.

Hello everyone,

As promised, here are the first tests of my "Bedini" proto
All aluminum and stainless steel construction
As much to tell you right away, I have not yet managed to get one on unit, but the tests are very interesting.

For cost reasons, I use the same neodyne magnets as the Hatem project, ie 20 x 6,4 mm, adhesion strength of 7,7 kg.

Here is Pele mele the first photos of the beast.

Detail of a door, for info I ended up removing the magnet facing the entrance.

I did not feel additional power with one or 4 doors, so I will try: 1 diver = 1 door, 6 divers = 6 doors.
Thank you for your feedback

I forgot to tell you, I have very bad fingers, these pu ... ns of magnets are very powerful, I managed to wedge them between the doors several times.

WOW
this is from the door Naca, Magnificent model !!!

for the moment we are basically at the same point I scratch my head to get more power output but good.

For the suggestions I am dry because I am also in neutral.

Bravo again.

Question:

6,4 mm magnets seem too thick for a bedini door

please
