Hi Sean,

Thanks for the kind offer, but I have already ordered a sheet of the HDPE as only ?22.00 for a 500*500 sheet and I will probably use it again for other projects.

No problems, I have a crate in the garage full of plastics and metals materials I have collected along the way, the same as you.

I will see how we go, I think I have enough acrylic for the rotor, first signs of something working and that's it, I'll be like a kid in a candy shop....oooh oooh, I'll have one of those, two of those and a bag of sherbit bonbons. ;o)

Regards
Rob

if needed, you can order from Germany diametrically polarized stator magnets(10mm):

or this one ring magnet made of gold:

the interesting thing to note is that practically any size of magnet stuck to the stator bearing will rotate in sync in the geared direction provided the airgap is adjusted accordingly. I assume that part of the tunning proceedure is adjusting the airgap so that gearing is instant. Since this was a quick and dirty stator experiment , i just stuck 2 magnets either side of a 5 mm bearing out of a kakkered disk drive ( i have others but i don?t want to magnatize them just yet.) The draw back of this was that at any speed in excess of 800 rpm on the main rotor caused the magnets to fly off of the stator bearing, but my daughter seems to like it, cannot get her away from the thing..lol

i might make a perspex ring to go around the bearing and drill holes to accept the magnets in the sides, as you cannot do any real testing with the magnets just stuck to the bearing,

@Craigy,

Recall that that's just the effect @gaby de wilde was talking about and @CLaNZeR started exploring prior to any clue that such brouhaha would erupt. There are couple of threads discussing it in this forum. I suppose the greatest problem will be to achieve the proper timing which is the major problem in making these motors work, plaguing the field. It very well may turn out that in the case we're exploring now the timing issue will be easier to solve than in other devices many of us already explored in the past. This remains to be seen.

I stopped by his shop last night, and he showed me the clear plastic he will be cutting the rotor and base from, so one can see through it to see that there are no cheater devices attached anywhere. He got the $2,000 sheet of clear 1/2-inch plastic for just $250.

$2000 How big was that sheet for that much money?

Maybe I misunderstood him, either on the size or type of plastic.

Craigy grrrrrrrrrrr I said I am waiting for the Proper Stator magnets to arrive before I start playing

Ummm and the Kiss motor Stator left overs dropped into my rig accidently below, before you ask!!!

ummm just realised looking at that picture, the magnets show you where they are field wise with the 13-8 magnet position config.

Hi Sean , will send you those 6 x 12 magnets tomorrow, the spanish post office closes at 2 , so can?t get there til sat.

yes the stators, they will all gear but of course , at .rpm the best shape is cylindrical. hence the magnets we are waiting for. i am tempted to turn a plastic cylinder and plonk 2 small neos in it., but it gets harder to spin the stators in the wrong direction when we are taking about a 10 mm stator diameter. perhaps if i put a plastic flange on them , thus it would be easier to spin up on the dremil

After this initial open sourcing phase of showing people exactly how to build one of these things, I would encourage those who are able to work on improvements which they can then patent and take to market. Doug will likely be one who will do that. I anticipate that Doug will also help us in the initial phase of characterizing what is going on: testing such things as magnet size, distance, position, etc.

Hi sterlinga,

Just curious, shouldn't this whole thing be open sourced and fully transparent all the way? None of the replications would be taking place if OC and Al were to keep their ideas and prototypes to themselves.
OC and AL led the way with fairly good transparency and open source spirit.

What would be the scope of patenting any further developments/improvements?

Thanks

ps: maybe a thread is needed to discuss opensourse vs patent? so not to take this too much of topic.

Yes, this should probably be a different thread.

My take on it is that open source is ideal for the core idea. Open source works fine in the software world from beginning to end because there are no significant capitalization costs. But in the energy marketplace, in order to get capital, one must have a patent; otherwise there is no assurance that someone else won't come along with a similar knock-off and make the capital investment not pan out.

No problems mate, got enough too play with for now hehe

Must admit I have played with those small 6mm Diametrically magnetised magnet and it takes a fair RPM to stop them interacting.

With the Config above, ya be lucky to get 3 revolutions, way too much of a sticky point LOL

When the orginal magnets arrive I think the only way to go for the constant speed is too use the good old Air Compresor to get a steady 400-600 RPM and then start spinning the Stator backwards, then as soon as a reaction is seen, cut the air flow. I have been flicking the small magnets all day and see what AL means by getting a sore finger

Another gawd knows how many hours wasted again, I HOPE NOT LOL

@All,
I have and idea that the three stators are required because they reduce the cogging effect at slow speed to smooth out the rotation and reduce the drag. This will be down to their different magnetic phase spacing around the rotor.
At first I thought that perhaps you could work this without them, but now I suspect they are required. I am not sure if AL has tried it with just one stator magnet - maybe someone can advise on this.

The large 19mm thickness allows the rotor mass to be sufficient to again smooth out the rotation.
So a thin rotor may produce a watch hand ticking action that prevents the rotor from syncing in the first place.
Therefore I think I will need to get some 20mm HDPE material after all and try to stick very close to the original design.

Regards
Rob
