Hi everybody,

@TheOne
I was also thinking at this kind of little square magnets (5 m/m) but I don't know if they are OK.

BTW: The European persons can find a lot of different magnets at: http://www.supermagnete.de/
Very serious compagny, IMO. (free publicity  :))

Best

they seem like they would be perfect for the shape of the halbach array being used in the orbo.
and if they don't work your only out a few bucks.
think i will order some.

what type of magnets do you need for the rotor?
wonder if you could use the same type.

this one are the cheapest

http://www.rare-earth-magnets.com/detail.aspx?ID=118

100 for 8.99

but its N40 instead of N42, that should not change that much for this kind of motor anyway, hum also they are smaller! :)

not sure if they are good for that

Could Steorn be trying to hide the actual configuration of the magnets in the stator by making them all look the same while they are really different pole configuarations and strengths to make a tilted, round, Halback array?  Hopefully a Vizimag example is attached...

Replicate the demo unit? It didn't work.


You have all the toys you need to replicate this thing.

if i understand correctly, the motor have 16 slots, on each of this slots you need 3 cube magnets to create a little halback at 30 degree angle approx, so you need this kind of magnet

this one is 1/4" instead of 1/8" or 3/16"

then you reverse the halback on each slot, and thats it?

Looks like they released the design diagram.  I think we still need to know specific sizes and spacing though.  So is someone gonna try it out?

They even mention overunity.com.

i think this drawing was made to disinform, first orbo have 16 slots not 8 slots, also the magnet inside the stator are not described

Here is another source for magnets:

(no connection to seller)

The device might need to be spun up to speed (complex start/stop stated by Sean).

So what's up? What do you talented builders think of dee dee's diagrams?

Anyone planning to build something based on his design? It looks pretty specific and also looks like what Steorn has.

Worth trying to duplicate?

not me for now, i don't have to replicate it, and still i dont beleive to much this guys since its appear from nowhere, its maybe just his own idea of how the orbo work, he did not show any device also... maybe in few months

I'm replicating another motor, soon with a new thread about it

deedee   "...actually only 50% truth...."
- Seems you're right. I like the idea, so tried to replicate.
Inside the box (stator) are 3 neodium magnets arranged in Halbach array and 4 weak magnets on rotor.
Tried different angles and distances.
Nothing; it's hard to fool fields; something else missing...

Light,

One difference between your setup and Dee Dee's posts is that he\she is describing a continuous array all around the stator but you have only a single grouping. You could be hitting unwanted edge effects. Try setting up 3 or 4 halbach sequences (180deg) and then see if you can reproduce the Steorn behaviour across a range of sequences in the middle (45 deg - 135 deg).

Thank you, Onevoice , you probably right, I've just used what I have. Gonna try 3 arrays, but to me it does not matter how many amplifiers applied (in fact this array acts like one), even one to one should show the "flow". I believe needa 4 magnets in array to make "flow" more stronger, and rotor's magnet better take a longer, with more expressed ends of poles; in this case pole should get 'immersed" in the array's "flow"...I guess...

People it's not the time to start replicating, I think we should do some numerical experiments. All this may be a fake. I've created a simple FEMM model with Halbach array and wrote a LUA script to automate the modelling process. If you decide to use the script, you should change file names that script uses (E:/test.fem, E:/temp.fem, E:/test.csv - look inside test.lua) to whatever you want. This script outputs results (torque of rotor magnet relative to (0,0) - center of rotor) to LUA console, and to test.csv file, which can be used to analyze data in Excel, also script computes total torque applied to rotor after one turn (360 degree). I used 5 degree step to reproduce the rotation.

I've attcahed an example of csv file that i've generated using test.lua, as you can see the result torque almost equals zero, and also you can see the graph of torrque.

Fell free to modify the model, i think we can play around with rotor and stator magnets relative angles.
