Title: About the Torbay concept (and I do mean concept)
Post by: lwh on October 08, 2006, 08:07:03 PM
Hey all. 

I've just recently finished building my Torbay replication.  It does everything it's supposed to do, except self-run. 

Sorry I don't have pictures, but I don't have ready access to a camera.

I've used improvised materials in the construction and so had to let that influence the design quite a bit.  This meant I ended up having the stators pivot outwards more than up and down.  Which in turn meant I had the top cap on the rotor pushing the stators in from the sides, much like others here have drawn and mentioned.  In my opinion, this variation is workable. 

What wasn't workable, for me, were the magnets I was using.  I had some 25mm Neo cubes (N50's) left over from another project, so thought I'd try using those to see what would happen.  One in each of the eight stators, and one in the rotor. 

Turns out the disk-shaped rotor magnet Torbay used in his patented design is essential for the thing to work.  Anything less than that long horizontal surface area has the stators repelling the rotor as they come down (or in) to push the rotor.

I hope I'm describing this clearly.  The stator magnets must come down to push the rotor well behind the leading edge of the rotor magnet.  This can't be done if the rotor magnet is too short horizontally, as the stators will repel the rotor backwards before they can repel it forwards.

It's pretty obvious really, and something I saw in the planning stages, but which I hoped I could overcome during construction.  But no. 

I can turn the device by hand easily enough, but the space between when the stator is repelling in the wrong direction and when it's repelling in the right direction is too small, creating too sharp of an angle on the rotor ramp, for it to self run.

I hope this information is helpful in some way.  I'd like to see someone disprove what I've found, and get a Torbay device working with readily available materials, but I myself won't be doing it, for different reasons.

One reason being, somewhere along the way, while building this thing, it occurred to me that the repulsion force that pushes the rotor forward is the same force that pushes the stators in (or down).  That is, the stators push the rotor forward, which in turn (in a roundabout way) pushes the stators in, which push the rotor forward, which pushes the stators in, which push the rotor forward, which...now hang on a minute. 

I just don't get it.  How can that possibly work?

How do the stators push the rotor when the stators must themselves be pushed by the rotor in order to push the rotor...aaarrrrgghhhh!!!!!

Okay.  Hang on.  So you push it yourself to get it started.  Then it just continues on by itself.  But what about all the friction inherent in the design, which can never be fully surmounted?  Are those forces of resistance of no consequence at all?

I don't know.  I just don't know.  It's a conundrum.  The stators, while pushing the rotor, are essentially pushing themselves, with some moving parts inbetween. 

Doesn't sound good.  Impossible even, I'm afraid to say.
 
How can the stators push the rotor harder than the rotor is pushing the stators (isn't that what's required for the thing to work)? 

Even if there are two or three stator magnets repelling the rotor magnet at once, they are still only pushing the rotor because the rotor, via the top cap, is pushing the stators.
 
Please pardon my ignorance, but it just doesn't add up. 

I can't see how it can be overunity.  I can't see how, even with precision engineering of perfect components, it can overcome the frictions and resistances of its moving parts and be self running.

Again, I ask you all to forgive my ignorance, if that's what's preventing me from seeing how this thing can work.  But at the same time, I have to admit, without regret, that it may have been wishful thinking on my part that enabled me to believe in the torbay device in the first place.

Please loan yourself a camera from a friend
and post some pics of your design.
Then we can have a closer look,
where your design error might be.
Did you use any springs at all in
your design to pull the magnets back ?

Many thanks in advance.

Regards, Stefan.

Heya Harti.

Sorry if my post isn't helpful without pictures.   

As for the springs, no, I didn't use any to pull the stators back.  With the stators pivot point below and behind the actual magnets, the stators move back very easily with just the barest help from the raising arm.

In terms of design errors, I'm pretty sure it all comes down to the magnets I used.  (That and the fundamental impossibility of the thing?)

But yeah, there might be something else I missed.  Would be good to get some feedback on it. 

I should be able to borrow a camera in a week or two, maybe sooner but only by chance.

i would say you are brilliant, not ignorant.  i agree with your analysis that it can't work, and you said it in a way that everyone should be able to understand.

Hey lwh, I hear you.
Good observations, I think. :)

I have studied this motor for myself for some time, and I didn't try to build it, because mostly the same reasons and problems you mentioned. I think this motor won't work in the original way, even if does somehow, it must be weak & delicate, and hard to tune it.

But I believe it can be modified to become workable, and the concept itself is a really good idea. I also like Mrd's and others creative attempts.

I think the Balance is the key for success.
If you can make an overall balace for every stator magnet in relation to the rotor magnet, you can easily move the stators with the force of the rotor. I don't know how it is possible exactly, but I'm affraid it can be more complex. I have a few strange ideas, but still working on it. Perhaps, I will post them, when I find the right solution.

The mechanics and the movement of the stators must be in perfect balance in relation to each other and to the rotor magnets. And in this case only one unbalanced part remains: The rotor with torque.

Regards,
Greg

Last one.  Too many complications arising with this close an arrangement of the stators.  I had to try it though.

Hi LWH,
nice pics and good craftmanship !
What do you think is the problem, that it does not work ?

Just the right magnets ?
Maybe if you can loan again a camera,
that also has a movie mode, maybe you can also
shoot a short video, showing, how the magnets
react against each other and telling in the video
when you speak, where the problems are stil
are located at.
Many thanks for this hard work.

Regards, Stefan.

Mulling this over I think we are going about it wrong. we seem to be stuck in this rut of having the rotor located on the inner circle and the stators on the outer circle.
think of a pivot and fulcrum you wouldn't try to raise the weight on the long side you would raise it on the short side but thats exactly what we all seem to be trying to do (me included). I think flipping this concept about would work easier.

Excellent work LWH

Are you using a milling machine/router to cut your parts?

Well done and keep going, I know how much time and effort it takes to experiment like this.

Where did you get those square magnets from?

Regards

Sean.

I used a loose hacksaw blade with a tea-towel wrapped around one end for a handle to cut the steel and aluminium parts, and a hand-held electric jigsaw to cut the round bit of wood.

I bought the magnets from a place here in Australia, I'll look up more precise details if you want.

I don't intend to continue with the Torbay type arrangement.

I've heard similar things mentioned before, and it's also crossed my own mind.  If I were to continue with this I'd probably head off in that dierction myself.  However, in my opinion, it still wouldn't work, and would just lead to a more efficient way of revealing the fundamental flaw in the Torbay concept (which I tried to describe in my original post).

Your center magnet is too small. It looks like just one magnet like the outside magnets, look at shipto's video and the drawings from the original patent. http://www.freeenergynews.com/Directory/MagneticMotors/Walter_Torbay/Walter_Torbay_Patent.pdf

I would agree that with only one magnet on the rotor which looks as if the field would only cover 30 degrees at best. The rotor magnet or magnets plural should cover 170 - 180 degrees of the rotor. You should at least get 180 degrees of powered rotation like that before encountering the typical problem of getting the stators down.

With 8 stators, your lonely rotor magnet is only being pushed by the magnet behind leading edge

I would agree with most of your observations, the up, down, Shake it all around ramp.. etc.is so full of friction that an alternative way of doing the same should thought about.

That darn torbay machine just won't go away!
I saw this post and started thinking again-which is never a good thing, he must have balanced forces there is no other way.
A spring could pull the stator arms down to match the repulsion force, but you would see them. But torbay uses a large base, so why not use a magnet in the base to match an attractive force with a repulsive force. The cam lifts the stator magnet at just the right time to match the repulsion in the rotor to the attractive force between the stator arm and a magnet under the stator arm. The rotor is attracted to the gap in the stator magnets and when it leaves the attraction magnet under pulls the stator arm back down.
That's my theory, It's all I got on this one.

Mmm, that's what I said in my first post.

Just let it go mate.  Or do something about it.  I understand the attraction, but in my opinion, the best anyone's going to get with a properly balanced Torbay design is something that will spin as if the magnets weren't there in the first place, with perhaps one added advantage.  And that is, you might end up with something similar to what you'd get if you were to balance a large weight on some roller bearings and start it spinning.  Inertia(?) will keep it going until the unavoidable frictions wear it down to a stop.  The 'weight' in this case though will be provided by the strength of, and degree of repulsion between, the magnets. 

At the risk of sounding rude, I'd like to say at this point I have nothing more to add to this subject (Torbay motor) that I haven't already said, and so won't be responding here again unless someone has some specific questions I might be able to answer.  If I were to continue discussing it without repeating myself I'd only end up raising questions about Torbay himself (his motivations, accountability etc), and I don't want to get into that (tempting though it may be).

Hello Les,
I agree 100% with your statement about the fact the horizontal rotor magnet must have some length. This is so that stators can be lowered towards the middle were the flux is the weakest. If the magnet is to long it will change pole to n-s on the ends instead of inside/outside.

Say for a 4 inch length if you place a north face magnet stator withing the first 2 inches it will repel in one direction but if placed in the last 2 inches will repel in the opposite direction. movement of the rotor does compensate for this slightly. But there is a definite balloon effect around the ends of the magnet.

One thing that I notice most people try to do is use Neo magnets. I personnally think they are to strong to work in this configuration. The magnitude of the flux field is to great. You would have to move the stators a far greater distance awat\y from the rotor to get away from the balloon effect.

I also believe that 7 magnet stators is the way to go not 8. I am uploading a new pic of my layout. Almost 1:1, off a few mm. If you look at the way 7 magnets set to the rotor you can see it is always off balance especially as long as the magnet in from of the rotor is missing. I explain where I am working from.

I think you did very well with your tooling but again I would not use metal objects which again will effect the lines of flux more than orgainc or plastic will.
