Magnet Motor from Argentina, part2

[FredWalter]

I just can't understand the necessity of lifting all these heavy stator magnets up and down on the
Torbay design. Just seems totally retarded

The saying "you'll attract more bees with honey than with sh*t" seems appropriate here.

Instead of wasting all this energy flopping heavy magnets around, why not just use the ramp to
raise lightweight Conetic shields up and down

I can think of a number of reasons off the top of my head:

1) it is cheaper to make a mechanism for moving the magnets, than to buy 'conetic shields' and make a mechanism for moving the shields

2) the original inventor wasn't aware of the existence of 'conetic shields'

3) the interactions of the magnetic fields, that you get with the moving magnets, can't be duplicated easily (or closely enough) with 'conetic shields' (or if it can, you need to do a lot of experimentation first, in which case you have to consider the cost of 'conetic shields' and equipment that will let you make/modify them)

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,

Thank you Gnostic has been a battle......Jason I have the same question as Gnostic, 'cause I have the interaction problem which made my rotor going stale or backwards depending on momentum and the magnets are ceramic type not that, strong.

Damn I can't find a suitablelfly wheel and the weekend is on us for vacations I'll keep working until the evening I can't waitt!. Enjoy...remember the heros.

Hi kukulcangod,

The problems you are having with the stator arms being pushed down will be solved with the rotor cap. The smooth spiral slope in the cap is the key because rather than forcing the stators down quickly, the cap gradually pushes them down along the rotation of the motor. You also have the bubble effect that will reduce the force needed the reset the stators. I mentioned this in an earlier thread but the idea is to guide the bubble of lifted stators around the circle, not force them down. With the correct adjustment of the lifting wheel and the stator cap, this can be achieved easily. I have made my model so that the lifting roller on the rotor can be moved anywhere on the rotor through 360 degrees to make it completely adjustable. Likewise the stator cap is also adjustable for every position needed.

I don?t think you will need to worry about the motor needing a flywheel. There is enough concentrated torque to rotate it from a standstill and with the moving bubble positioned correctly; you will always have an imbalance of forces through 360 degrees to keep it from hanging.

God Bless,

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.

Hi Everyone,

I was attempting to put a few last minute pieces and parts on the 3D model ....

Hi Jason.
I think that the TOP (image004.gif) is different from the pictures that Omnibus sent us. You use the whole rotation to bring a popped up magnet back in line with the other magnets, and Torbay uses only a part of the rotation to bring the magnet back in line.

Eric.

Hi Eric,

Now that I look back at the original pictures again I see what you mean. It looks like the spiral is only covering 180 degrees of the cap rather than 360 like I have drawn. What do you all think?
