Working Magnetic Motor on you tube??

[blue_energy]

As seen, my rotor being 303g is heavier than @alsetalokin's 258g rotor. Don't remember if that 258g was with the eight magnets and the two bearings or not. Also, I don't remember seeing how heavy each one of @alsetalokin's stators is. As I said, each one of my stators (Delrin holde + bearing + ring magnet) weighs 10g. This is one thing we have to work with to make it as close to @alsetalokin's as possible.

My next step, being stuck for the time being with the weight of the rotor I have, will be to try different stator bearing-ring magnet combinations which is a study @alsetalokin considers important because he says in his experience not all such combinations work. Not clear, however, what he understands by "work"--does it mean AGW can be achieved with any combination but the acceleration doesn't kick in with just any combination?

Yes - 258 with magnets.  No mention of bearings one way or the other that I recall.

In trying to tune the motor and conduct various experiments to optimise COP, would there be any mileage I wonder in applying a constant drive from a small DC motor, fed from a voltage variable source, to the main rotor and monitoring the draw current of the driven motor with a DMM and/or the speed of the rotor of-course? This should permit some tweaking of stator positions (etc) with either the motor in operation, or statically with a re-run to compare against previous results.

Of-course this would rely on the AGW stator sync'ing up as ultimately required, though I would expect the current of the driven motor to fall and speed of the rotor to increase with an improvement in efficiency. Heating effects in the motor would cause some deviation from absolute measurements, though if trimming were conducted dynamically then you would be looking for clues by relative short-term deviations in current demand and rotor speed.

I'm suggesting this as there appears to be a few unknowns with regard to Alsetalokin's device, and who's to say that the physical deviations would not need to be surprisingly considerable from the original - particularly as there's a fine balance to be struck?

Now dump current the other way and you've really got it cracked 


Just a thought

Ok, I am kind of reaching out here so bear with me. On the second video(File 13). After he removed the rotor, he then flipped over the base. Adjacent the rotor bearing assembly there was 2 hole also drilled into the base 180 degrees apart. There was never any explanation for these to holes, So I was pondering on that maybe there was an cylindrical magnet in each hole to induce instability or a magnetically induce ratchet effect into the stator magnets as OC spoke of. Maybe I am out there, but wanted your comments on this possibility or consideration.

@vipond50,

I think he explained it somewhere that that's where the construction for the pivot is attached. Seems to me it's more important now to start with the basics:

a) Weight of rotor--original is 258g w/ 8 magnets and bearings (mine is 303g).

b) Weight of each individual stator--I didn't catch what the original weight of stator holder plus the ring magnet pus the bearing is (mine is 10g).

c) Magnetic induction of the stators with respect to the rotor. We know that, in general, the stator magnets have to be stronger than the rotor magnets but how much stronger?

I'm most curious, if @alsetalokin orders the parts the same way we did, using Jason's fine drawings, ordering the same magnets and bearings we did, will he be able to reproduce the acceleration we see in the video, let alone run the machine for 7.5 hours?

Hi Omni,

I had looked up the weight of Al's stators some time ago, and they were 10g.  So yours are fine.

I suggest two things.  First, is using identical damper material as Al.  6061-T6 Aluminum Alloy.  I paid $5.00 for a 12" piece and I am waiting for it.  (and my correct sized rotor)  Any other metal, including pure aluminum will not be the same.  It will change the braking, etc. 

Secondly, testing with different strength rotor magnets.  We want a 30.5 mm separation if possible.

Oh, and lastly, measure from the outside of your stator, to the outside edge of your rotor.  Al mentioned it needs to be exactly 5 mm.  4 and 6 mm will not work.  It must be precise.  (Al's statement)

@ Bill
I would strongly suggest ordering the 6061-T6 Aluminum Alloy for your replication.  It will make a difference IMHO.   

Cheers,

Bruce
