Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

[Dingus Mungus]

The real question here is: What was the original rotor/magnet configuration? Anyone have a photo with an object in it to use for digital size refrencing? What kind of flux pattern are you guys looking for? How large is the buffer zone between the windings and the rotor?

I'll re-sim both models with a ferrous core tomorow at work... Altho IMHO it would be easier for me to design a rotor for who ever would like to use it with of the shelf parts in a simulation. All I would need to know is what kind of flux pattern are you looking for: many peaks or a smooth cylinder?

I don't think we know exactly the construction of Mike's rotor.  I would say it is more similar to your first simulation than the second as far as magnet size and spacing.  I don't recall whether there is any information on the materials in his rotor.

I do recall some of John Bedini's posts saying to use a ferrous rotor, but almost nobody is doing that.

As for what kind of flux pattern we want, I don't know.  I'm trying to understand how changing some of the basic parameters of the rotor changes the flux pattern.  In a normal motor we would want a high flux density where the coils intersect the rotor.  With this motor I'm not sure.

It is clear that the spacing makes a big difference from what you did already.  With the closer spacing we got a lot more flux density off the face of the magnets.  I am wondering whether changing the core to something magnetically conductive will cause more or less flux out where the coils are passing by.

I still suspect that the flattening of Sam's waveforms has something to do with the drop of flux between the magnets because of his spacing.  I still don't know that it really matters either.

I have been struck all along by how sinusoidal Mike's waveforms were.  I did not expect that from seeing the motor.  I expected something more like what Sam is getting.  That is partly what made me start to wonder about what the exact flux pattern is or should be.

If it is trouble to do the extra sim's, don't worry about it.

Something i notice in the film is Mike is using the Black and Green terminals on the breadboard to power the electronics, but in the static build he uses red and black, what does the green terminal do on that type of bread board, how does it connect to the prototype area.?

Peter,

Those colored terminals are not connected to anything on this breadboard. The user must place jumpers from there to the board rails of choice.

I have this very same breadboard.

Hi Darren
that explains it then, so it doesnt matter which he uses.
