Hi All,

Please see my latest video with a proof of concept motor. Not optimised but runs as expected. Much magnetic and eddie current drag on the rotor and significant CEMF when compared to the orbo which keeps the RPMs lower for the input power.

But much was learned. Better eddie-less core material would be of advantage to this design. But going back to individual smaller toroids with magnets in them or behind them will also be looked at.

Great! I like your ability to experiment with new solutions!
thanks!

Why is everyone overlooking using pairs of magnets with the same poles of each magnet attached to a metal backing plate?  This is key and a very important feature IMO.  I made these changes in my setup and got excellent results.  If I didn't think this was important, I wouldn't be sharing this.  This is how it's setup in the Orbo and it appears to be ignored by most of the replicators, unbelievable.  I was almost ready to give up on this replication, but now I have new hope.

This is why I released a video on it, because prior to this it would barely run without the neo's being attached to the coil and ran very hot.  After I made these modifications it is faster and runs without the heat.  Attaching neo's to the core has no noticable affects and may even hinder it slightly after I made the changes.

This allows the toroid core not to lose magnetic attraction as the magnets approach the core which allows it to gain additional speed.  It also uses Newton's Third law to defeat the CEMF of Lenz when the magnets depart from the core (one magnet is attracted to the core after being energized and the other magnet is repelled by the opposite side of the core, thus canceling each other and allowed to pass by without opposition).  The flux doesn't fully engage the core immediately when the coil is first energized.  I can't stress this enough.

The core I am using is a thick collar and it is heavy.  I wish I had taken a picture of it before I wound it.  I have no idea where I got this collar from either.    I will try to find something similar to it.

Working with my replication, I noticed something interesting that nobody has seemed to touch on yet.  I will try and make some video's shortly, as my video camera has shot craps on me, and I'm working on a solution. But my current setup has 4 steel washers (actually really thin bushings), each with 1500 turns of #26.  I previously posted some pics of the coil I was using back around page 43 or so I think.  Anyway, my rotor is set with 4 pairs of magnets, and is layed out exactly like the orbo.  I've been running and testing it with opposite poles facing the toroid.  North on top, and South on bottom.  I have one sticky spot as the magnets pass, and it is in the center of the coil as expected.

Following what I have seen from others experiments, I decided to go ahead and flip around the bottom magnets, so all magnets are North facing out.  All of the sudden, it is impossible for me to line them up as the Orbo has it, with all like poles, and get only one sticky spot.  I now have 2, the two outside edges of the coil, and it floats past the center to lock onto either side.  Just like Ossies one magnet setups.  What I find odd about this, is that it is obvious in the video's that Steorn has one center sticky spot on their coils.

This means that I do not see any way Steorn is using like poles facing out.  There is no way I can set this up and get back to only one sticky spot using like poles, unless I change the layout to look completely different than the demo Orbo does.  Using like poles does however make the rotor move by the coil easier, but it is not the way the Orbo is made in the demo.

TK's demo showed increased rpm when he changed to like poles, but he also only used one outside edge of his coils.  Not to mention, I think it is possible his added speed was simply because he doubled the number of magnets he was using.  I have not tested biasing the coils with magnets on the back side in relation to like and opposing poles on the rotor yet.  I will post what I find out.
