The bearing motor

Searl SEG

It seems you are thinking along the same lines as me Mags,as i made reference to the SEG in my first post. Here we apply current to create magnetic fields which creates rotation,where as the SEG uses magnetic fields to create rotation that creates current.

Im waiting for my device to get liftoff lol.

Nice demonstration however I don't think it discounts the Lorentz force completely it simply means it may not apply in the way I had originally thought. I think I have to agree with MH on this one and say it should apply but I have yet to determine exactly how and where and why.


Thanks for doing the demo because this means we can rule out a fair amount of things we can assume should not be happening. I did the basic tests however I am going to have to go back to the drawing board on this one... so it works with AC in both directions and DC in both directions?....Hmm.... that is interesting.


I should have a better solution in the morning.

This is a vid I did just a while ago. It must be showing the same effect.

And this is the vid I saw yesterday that shows with and without magnets.  Can FF to the experiment beyond the assembly of foil tracks.

It appears that the addition of magnets not only gives self starting, but has more go also.  So there may be an improvement in adding mags to the bearing motor.

Tinman:

Yes I was not 100% sure that the motor would only run in one direction as reflected in my choice of words.

So what is the reason for stating that it's not surprising that the motor runs the same way when you flip the polarity?  The reason is very simple.  For starters we know that the motor runs because of the Lorentz force.  That force vector is the crossproduct of the current flow with the external magnetic field.   We also know that in this case the current flow itself produces the external magnetic field.  So if you reverse the current flow, you also reverse the direction of the external magnetic field.  So it's like a double-negative and you end up with a force vector in the same direction when you flip the polarity of the applied voltage and do the cross-product.

So that means the motor spins in the same direction if you reverse the applied voltage to the terminals.  So yes the motor will run on AC, but it is certainly not an "AC motor" in the normal sense of that term.

As shown in your clip the motor will run in either direction.  It's just a question of working out the geometry to explain everything.  It's like Bill said, this is just a variation on a homopolar motor like the one people make with a standing AA cell and a paperclip.  It's also just a variation on one of those mislabelled "swirling aquarium water and bubbles" clips.

Somewhere within the bearing structure you have current flow at an angle with the external magnetic field produced by that very same current flow and that is creating a tangential force that results in torque being applied to the motor.   That is the only possible explanation and the real exercise is to figure out and show where it is happening.
