Building on the Calloway V Gate principle.
« on: July 05, 2007, 02:40:42 AM »
First off, go to http://www.youtube.com/watch?v=kCr3lOhMJCg&mode=related&search=

Skip to the end (about 20 secs before it finishes). What if you fixed the skateboard wheel to the axle, attach to the axle two "spirals" of plastic, http://www.photolava.com/view/3ntj.html (excuse microsoft paint); either side of the wheel. Then you make another axle with the magnet and rest it on top of the cams, so for every rotation, the cam moves the magnet away, as needed for the wheel to rotate.

Concept here (ms paint again!)

Hello,

I think it would be worth experimenting with your suggestion, the crucial area that needs the best engineering possible  is where the cams touch / contact  the second axle that holds the (reciprocating) magnet.  If you could make the friction at the minimum possible between them, it would be a better chance for a self-runner.  Maybe using ball bearings on the second axle that could roll on the thick enough surface area of the cams?  Still the suspenson / appropiate holding of the second axle is also of importance.

Can you make some experiments on your idea with the cams and the second axle?

There is the second part of the video you referred to above, see this link:

I don't really have the tools to carry out such an experiment; but if anyone else does, I would be interested if you could email me the results.

I had this very idea after watching these two videos; in fact if you go to the second video, and go to the messages left a month ago you will find one left by JamesThomas that suggests the cam idea.

Now as I recall, as I was researching prier to actually doing the experiments, I came across on the web someone who appeared to be very knowledgeable regarding magnetics saying that the hand action of moving the stator magnet away from the wheel magnets (which can be done in a lot of other configurations besides the V-gate) is doing way more work than can be derived from the spin of the wheel...which would be needed to make a mechanical cam mechanism work. This dissuaded me from moving ahead with the idea.

Having not done the experiment myself, I'll never really know.

i would like to try this skateboard wheel out...i have tried to count how many magnets he has and so...can anyone tell me how many it is needed and what kind..and the size of the wheel...and perhaps how to draw the lines...and perhaps any improvments that can be made...i have tried to contact him on youtube but he will not awnser :(

@at everyone
have you ever thought that he might just be wanting to improve the efficiency of the skateboard?  hmm those suckers are sure hard to keep going if you are trying to go uphill!

is there any other configs other than the "v gate" to try out.. imena the v gate i can understand and (build in my head) :)...but if you all say it wont work..that can you try instead??

i just had an idea that i read on the "youtube video of this v gate" if you had 3 or more wheels..wouldnt that perhaps keep it going over the "flux".. you have 3 wheels..at all time 2 wheels puch the 3rd wheel over the sticky point?? or is it just and crazy wierd idea perhaps?

how about  spiralling the gate up a cylinder that is cone shaped and adjusts for the height changes in the magnets....in this way you wont need some fancy mechanical adjustment.... ???

anyone think that a cone could be a thing to try out :)

armagdn03 you are right about the cam not working.  I talked to him directly as I had the same idea.  He said he had thought about posting on YouTube as he had tried the cam and in fact it didn't work.

I kind of like the cone idea. Introduce an inclined plane into the equation. Interesting.  I hope someone with more available funds than I (right now) tries this. I can't afford one skateboard wheel right now... ha ha

You want to adapt the hanheld magnets motion? I see. It looks promesing, but the movement of the hand is in fact adding energy to the system - energy taken from the man who held the magnet. If you are gonna provide similar force by getting it from the rotor itself, this force require energy - energy you don't have. The rotormagnet and the stator magnet will allways work against each other, and cancel out all forces in sum. I'm afraid your idea will therefor never work no matter how hard you think on it.

Howdy,

Thanks for taking a look at my Calloway V gate magnet motor. To answer some of the qestions, my hand is doing work. There is a great pulling force in attraction mode and the cam idea will not work due to friction. Not enogh power in the initial spin to get the cam working. I've tried it and it just stalls on the cam.

The drawing above is something I want to try, but don't have the tools to build or the time. I get about 6 comments on the videos every day and I have no time to answer them all. Sorry if I haven't gotten back to questions, there's just to many of them coming in.

I think the only way to get this to work is to build a balanced, inward spiral that dips the gate about half to a full inch into itself.

It's made from a 83mm skate wheel and has 26 magents on each side of the V. I tried to space them so the space between the magnets was half the diameter, but it ended up being about a full diameter space between them. The diameter being 1/4".

I tried placing a ring around the wheel with three stator magnets, so two would push the third through the gate, but the gate is much to strong, it didn't work.

If it was easy, everyone would be doing it. Good luck with all your ventures.

Thanks again for checking it out.
