Torbay's motor does a LOT of work just turning the rotor, topcap, and lifting ramp. Also, the lever style lifting mechanism seems to be a bit bulky, seems to me something far smaller could do the job, further reducing the weight the rotor has to carry.

When you are thinking about all that weight, think "flywheel".

Flywheels are perfectly balanced, which the torbay parts are obviously not. Not to mention, they take a long time to spin up.

At any rate, I like Jason's design a lot. Very nice. One question; Jason, do you think the angle of the cut on your stator magnets is enough to prevent interaction? Also I was looking at them, and I noticed you had what looked like a ceramic mag sandwiched between two neos, is that correct? What's the purpose of that?

Also a small wheel on top of your stator magnets might reduce friction on the topcap.

Hi gn0stik,

I figured out the size of the ramp from studying the photos from Torbay?s models. Since this model is designed from his wooden model, from measuring the dimensions of the parts from the pictures, you can see that the height of the lifting ramp is roughly equal to the height of the magnets. So he is basically lifting the stators one magnet length high. But this is not absolutely required because as we know from the experiments people have done here, and from Torbay?s patent drawings, that lifting the stators as much as half a magnet length is sufficient to create the unbalance of forces. I made the ramps one magnet high to stick to the original model but that is something that could easily be adjusted.

As for the thing between the two stator magnets, that is a piece of steel. From studying the pictures, you can see that the ceramic magnets Torbay is using have a slight taper from the north to the south pole end so to mimic the effect; I used two neo magnets with the tapered piece of metal sandwiched between the two. This serves three purposes. It helps to shade the opposite pole to reduce south pole interactions with the rotor, it also makes it a little easier to press the stator arms back down because you don?t have as much field concentrated at the north pole end as at the south pole (this probably wouldn?t make much of a difference in this case the way I designed it). Lastly, the metal provides a base to secure the magnet setup to the stator and gives some material to mount the rollers onto.

Speaking of rollers, I do have them on the model now. They weren?t pictured in those screenshots because the model was not as complete in those pictures as it is now. I am still putting the finishing touches on it now and will be adding the screws and bolts to go in along with the rollers. Then I will post more screenshots and the final CAD files.  I won?t be too much longer. I am working on this in between my research work.

God Bless,
Jason O

How big of a cutting area can your CNC machine handle?

I don't have any CNC machines at the moment. I do have a Sherline 2000 milling machine, which I want to CNC when I have time and workshop space. The specifications for Sherline's machines are here: http://www.sherline.com/specs.htm

If you could get the parts sized so that they could be constructed on a Sherline, then there would be thousands (or more) of CNC hobbiests across the USA that could make them.

For my Sherline 2000: x-travel 8.68", y-travel 7", z-travel 5.38"

I can handle 120" x 60" x 30"

The biggest solid part (other than the base) is the 8" diameter rotor cap. I'll probably make a smaller version later once I find some suitable magnets to use for the rotor. Short of having them custom made, I was thinking we could use some arc magnets like the kind that go in small motors. The only reason this model is larger is because of the arc mags that Dan LaRochelle has already.

I think it provides for scalability for larger models. You could have a dual ramp dual rotor mag setup that way. However on a single rotor mag setup, It's probably better to have the longer ramp, to reduce the amount of work it has to do all at once to force the stator back down.

On the other hand a shorter ramp might reduce the amount of travel that the stator has when initially forced upwards by the lower ramp, which would lessen the impact on the topcap due to the reduced "kick" the top cap would experience when the stator pops. This could help with keeping it in balance and hence preserve torque and momentum.

I guess it all depends on what produces the greatest amount of loss in the system, the impact on the topcap, or the friction of forcing the stator back down. My bet would be on the friction of forcing the stator back down, as the upward kick could be mitigated via other mechanisms fairly easily. For example, you could build a ring over the top of the stator arms that would limit their travel, and allow the topcap ramp to contact them passively. Determining the optimum height of that ring would be key, but having it about mid ramp would be perfect, I'm guessing. Having it higher might be required to optimize the magnetic "vaccuum" effect that runs the motor. This ring would have the effect of eliminating the impact altogether, and reducing friction and contact time on the topcap. Win-win.

Buenos Aires. - The marplatense scientist Walter Torbay was distinguished by the University of New York by his discovery of the Magnetic Transgenerador, a device that through the magnetism can get to generate 1,930 watts of power of 220 volts. Torbay, that is director of Scientific researches and Tecnolo'gicas Independientes (ICYTI), with seat in Sea of the Silver, traveled to the United States invited by the University of New York, whose authorities proposed the accomplishment to him of seminaries and to char them explanatory of the discovery. "To that seminary scientists of several points of the United States were invited and also they attended the directors of other universities and the prestigious British scientist Vesselin Noninski, director of the Institute New York Sofia", emphasized Torbay. The prize of the University of New York consisted of two honorary plates, a computer laptop and 15 thousand dollars in cash. "Astonished by the obtained results, they made me arrive his recognition and they gave in writing a note to me certified in which they are committed to present/display in August next like precandidate to the Nobel prize to me of physics", it affirmed the marplatense scientist. Considered Santo Grial of the Energy, the discovery of Torbay uses like only power plant permanent magnets, taking advantage of the magnetic property by ricochet equal poles, the deviation of lines of magnetic force and a complex mechanical system that transforms the locked up magnetic energy into permanent magnets in motor, electrical or caloric energy stable and 100 ecological percents. This device generates 1,930 watts, when an average address consumes 1,500 watts, and does not need maintenance. "At the present time the investigations continue, in this stage I am developing a new model of the Magnetic Transgenerador but this it will be applied for the operation of automobiles", indicated the scientist. In as much, it emphasized that it follows "the delay of the concretion of a support on the part of the governor (bonaerense)Felipe Single, to be able to continue with the investigation in Argentina and finally to be able to begin to make it in p

(...)does not need maintenance(...)

Anything with moving parts needs maintenance. Moving parts require lubrication, and eventually wear out and will need to be replaced.

Good idea Konduct.I might use it by the dozens in my stacked up version of the Torbay generator,

Thing that got me thinking is why I didn't hear anything about  Torbay here in New Jersey??!!!!

Now come on!  a month ago or so this hapened?? I watch the news in spanish and english, from there and here and... and nothing has been said , they keep talking about the gas prices as if we where still in the dark ages in contrast to the Torbay's discovery??, what's with that??

well  let's hope that everything is truth 'cause the site for the university is not mentioning anything at all at least 2 weaks ago  when I searched. I'll keep looking but this is weird to me I'm just a few minutes away from Manhattan and the bronx through the Washington bridge for that matter.

Now I wonder ...is there going to be any restrictions as per the used of this motor by independent constructors like us .Good Luck

how do these clips flip up and down? how do you lift them? how are they oriented?
