new magnet ball in a tube motor ?
« on: October 15, 2012, 02:44:53 PM »
Has there ever been a magnet ball in a tube motor ?
I could only find one video that was similar to my idea,
but instead of a tube he used copper rails and a only one toroid coil
http://www.youtube.com/watch?v=aTp6IN4jy64
Any thoughts on this idea

A magnet going through a copper tube,
but I can't find anyone that has made a tube motor.

Hi twinbeard
sorry that's not what I was meaning.
picture a circular piece of tube with a ball magnet inside,
and the tube has a number of toroid  coils attached to the outside.

Then control the speed of the ball using something like the circuit
Shown in the first video.
or something like that,........... it's all ideas......... and I have never seen one before.

Wilby
Thanks but  its not in a continuous circle.

I keep finding lots of videos where people spin the magnet ball in one place,
rather than the ball spinning round and round in a circle tube,

Rather like a gun barrel that is looped and the ball magnet is the bullet,
If that helps anyone.

Sorry for the poor sketch but I hope it helps understand the idea
The black is the tube.
The green is the toroid coils
The red is the magnet ball

I have never seen a motor/generator like this ever before.

Thats like an EPG with a magnet inside instead of ionized plasma.

Hi powercat,

I think your setup is a good idea, worth building a testbed for it.  If you do not mind I would suggest an addition which may help the moving ball accelerating, besides the coils.
You surely heard of the magnetic trigate setup from Graham, see a video collection on it here:
http://www.youtube.com/watch?gl=GB&hl=en-GB&v=pnMSSz7W8YU 

See this test here why I think your setup could benefit from the trigate magnets addition:
http://www.youtube.com/watch?v=MCW6T7oKq2c

If there is any small sticky point at the entrance or near to the entrance of a trigate setup in itself (though I have not noticed such in the videos) then it would surely be defeated by the momentum of the moving ball and I guess any DRAG by the induction of the moving ball in the generator coils around the tube to generate output should be much higher than the trigate any sticky spot.

Hopefully you can build this, looks promising!

rgds, Gyula

PS  EDIT  I am not sure if the trigate setups placed around your tube would be able to accelerate the ball without the electromagnet coils...  because bending the trigate may distort the fields in an unfavorable direction,  so just use one or two trigates first for a bigger diameter tube like at least with 40-50 centimeter.

Hi Powercat,

There are two patent applications by the same inventor based somewhat on the idea. He is using rounded cylinders though.

Application number: 12/778,500 CIRCULAR SELF-POWERED MAGNETIC GENERATOR
http://www.google.com/patents/US20100219709

Application number: 12/910,912 GRAVITY-ASSISTED GEOMAGNETIC GENERATOR
http://www.google.com/patents/US20120098272

The cone shaped coil construction is pretty interesting. I haven't seen a generator use that coil geometry before.

Hi Gyula,
thank you for those videos, yes I have seen some of them before, interesting as a possible way of assisting
the magnet ball, I also had some more thoughts.......making a vacuum in the tube for more efficiency
or possibly a double layered tube, with one layer filled with liquid nitrogen.

Before attempting a build I would like to understand more about how efficient this could be.
I prefer to build with off the shelf parts if possible as my skills and knowledge are limited,
it is good to share ideas and information with other members before taking a leap into the dark.

What I'm still finding strange is that I cannot find any motor/generator that has been made this way,
Is this a unique idea ?  Time will tell.

Hi DreamThinkBuild
Thanks for that information very close to what I'm thinking, though he was not using a magnet ball,
the train carriage like system is interesting, would love to see a video of it in action.

The other problem is this is a very custom built device looking at the drawings nearly everything is handmade.
I know there are some good coil builders out there that might be capable of some sort of replication.

I feel the search continues to see if this (magnet ball in a continuous tube) has ever been built before.

Hi powercat,

I have not seen your setup yet either anywhere else but this is no problem, rigth?

In fact there is a "twisted-out" version of your setup and I mean:

1) the tube does not exist but substituted by stationary coils arranged in a full circle with gaps between them    (you could easily   embed them into a ring-shaped tube or you could use a non-magnetic ring to hold the coils  mechanically as bobbins as you yourself show)
2) the ball magnet does not exist but there are magnets arranged in a toroidal shape and each of these circular magnet sets  rotate outside of and around the stationary circular row of the coils

The inventor (from Germany) shows his setup as a low Lenz generator (not motor) and for the tests he rotates his setup by hand as the "prime mover" and shows loaded run down tests. Here is his youtube videos as he uploaded them in time:
http://www.youtube.com/watch?v=9TEemaW9_CE
http://www.youtube.com/watch?v=bfgzfl69Q20
http://www.youtube.com/watch?v=__B9obbzreQ
http://www.youtube.com/watch?v=rX5ukoC-WXU

and here in his latest video he shows magnetic induction with "three fields":
http://www.youtube.com/watch?v=Vmr5AlwH1GM 

I do not understand German and I am puzzled by his statement that he has a low Lenz generator setup,  of course I know he comes to this conclusion because of his comparative run down tests with load versus the no load rotational time.  BUT what I conventionally tend to think is that his magnets are far away from the coils so action-reaction is limited and if he connected all the output coils in series, so his generator inner resistance is relatively high (Lenz reacts in a lessen degree when current is smaller).
Of course I do not wish to discourage you or anyone else with this "rambling", just my own observations.

rgds, Gyula

Hi
the German videos were very interesting but what a build way beyond my capabilities,
if I do built this motor/generator I will try and buy everything off the shelf.

Another idea today is to fix the whole device on a bicycle wheel and then spin the wheel
using another motor, so the magnet ball in tube will only be a generator.

Hi Powercat, I played with the idear a few years back:
