Forgot to add the video :)

Shows how loose they are using one of the small Magnets.

@CLaNZeR.. Nice work sir! I was wondering how you would make the magnets movable on the "X" & "Y" axis.

Thx Starcruiser

I am now wondering whether to press fit the Brass Axles directly into the Stator Magnets, rather than lathing the Poly Rod to seat them in.

Anybody have any reasons why I should not press fit the Stator magnets directly onto the brass axles?

Good stuff Sean,

I am thinking of mounting the spinning stators in the same way as the rotor , i.e on a shaft of say 30mm , supported in bearings top and bottom. You may have noticed that my shaft is threaded rod with the ends turned to fit bearings. I wondered about turning a shaft but that meant dieciding on a height. Since i belive the interactions between rotors and stators are not on exactly the same plane ,perhaps 5 or 10 degrees off. The bolted rotor makes it posible to lower or raise it in relation to the stators. Not sure if that will be useful of not , will have to wait for the other magnets to arrive.

Hi CLaNZeR,

The NdFeB magnet material is pretty brittle once the magnets are sintered. So you may run the risk of them shattering (while press fitting the shafts or while they are in motion later). As for the brass itself, I don't think that would harm it magnetically.

God Bless,

Must admit mate I do like the idea of have the threaded brass rod as the main axle, as it allows you to alter the height of your Rotor to suit, instead of trying to get the Stators to match the height of the Rotor. With mine I have left the middle axle exactly 8mm and Press fitted it into the Rotor, I can adjsut but getting it to sit square would be an issue. Ummmm might have to get the Tap and Die set out again :)

With the design you have there mate I would make you Stators Static in height as you can adjust your Rotor to suit.
On your lathe you can get the Stator Axles exactly the same length with a V either end to take up the slack.
I did think about top and bottom mounting of the bearings for the Stator but was abit concered about running a brass rod through the whole length of the Stator magnet. Whether it will effect the effect as such, I do not know!

Thanks Jason

I do think we are safe with brass not interfering too much and I agree with the magnets destroying themselves very easly, especially when they slam together LOL

I have a pack of 10 coming so will see how tight I can get the tolerance of the Axle and not push it too much.

Cheers

Sean.

@CLaNZeR,

I wonder if brass would be the best. Eddy currents and such ... However, we have to know what @alsetalonkin used because these eddy currents may be needed for it to run. The stators are mounted on plastic axes, correct? I'm still not clear exactly how these pieces (both rotor and stators) are mounted in the original. There are various ways but sticking to what was successfully done is the best strategy, I think. (recall the failure of @xpenzif's motor because it occurred to no one to use 14-diagonal row cylinder with an 8-barrier stepper motor and that compromised the replications; that was @xpenzif's fault not to emphasize on that.)

See, @alsetalonkin denies that such details are of importance and that may turn out to be so ultimately. For now methinks we should be true to the original, don't you think?

Originally AL used Nylon bolts from what I see and mounted the bearings on these.
I have used Nylon in the past and yep handy for making sure no Eddy currents are created, but on the down side are the bearings really sealed against that Nylon and hence slipping while turning. Atleast with brass we can nearly guarantee a snugg fit with no slipping and hence cutting our friction losses.

The only plus thing about the video we have seen is the accelaration from just over 1000rpm to over 4000rpm. For anyone that has played with Rigs and Rotors that is actually bloody incredible.
With a really loose Rig you would struggle to get it past 1000rpm with spinning by hand and no way would you ever get over 4000 rpm.

This is why this weird effect is so interesting and if it is real then I should think with that much gain a little bit of drag is not going too stop the effect happening.

Hi Sean,
When you ordered from K&J Magnets in the US, did you exceed the value of 18GBP (34USD) ?
According to the HM customs page if you exceed this then you have to pay duty and that will be to ParcelForce (handover from USPS) who are a real pain and levy a heavy charge for paying the duty on your behalf.
Also it slows down your order.
http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp.portal?_nfpb=true&_pageLabel=pageVAT_FAQs&propertyType=document&columns=1&id=HMCE_PROD_008566

I was thinking we could have split the postage but its the duty on a double order that would negate this idea.
If you can get K&J to mark the package as a "gift" then you can have 36GBP worth of goods before you pay duty.
I have just asked this question to see if its possible.

Hope to start building the same as you very shortly - time to play with the router table again.

Regards
Rob

OK, I guess you're right about snugness. As for the effect, I won't probably emphasize on the 5000rpm because of that argument with the decreasing moment of inertia causing the increase of the rpm to conserve the angular momentum. It'll be enough for me to se that after I've imparted by hand 400rpms to the rotor, the rotor kicks in, accelerates and spins at 1200rpm for 3 hours. Will try to have this done in a Faraday cage to kill forever the silly suppositions that the effect may be due to tapping energy from the local cell phone antenna or the local radio station.

Hi Rob

My order only came too $17.10 so should be okay.

I know what you are saying though, have had many a Duty slap of 20% (By the time the Courier puts their admin fee on) when I used to order alot of components from the USA.

It was only after I placed my order did I notice they also did 1/4 inch rod magnets in different lengths and wished I has ordered a few. Managed to get some 5mm ones in UK though.

I would be even happier if it was picking up some sort of RF signal and creating that effect I must admit!. Any schoolboy Pyshics class will show how you can tap nearly a volt from think air, but as soon as you try to pull current it ain't gonna drive alot and must admit these claims of charging mobile phones is interesting but stretching it a bit.

If the RF signals or any other stray signals can create an effect on magnets like we have seen in AL's video, then I will be buying a house next to a mobile phone mast hehe  ;D ;D

We recently stroke a deal with such company to build their antenna on our property and pay us a monthly rent for that. So, you say, had we found a proper device we could also steal energy from that. But that's stealing (forgive the frank language) while I think what we're working on is producing energy from nothing. Anyway, just a little friendly chit-chat now while waiting for the magnets.  My friend already started the lathing an milling, the magnets and the bearings will arrive soon and it'll be seen shortly what we're facing.
