Working Magnetic Motor on you tube??

[CLaNZeR]

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.

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!

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.

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

@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.
