Tinman's Rotary Transformer

[Magluvin]

Hi Mags,

thanks for the reply.

From what you have written I feel you may not understand my motor design or have forgotten how it works!  as there is NO " release pm magnetic pull after a magnetic event with cores and such"

Here is the most up to date video. Have a look and let me know what you think.

Just watched it. I remember seeing it. Remember I commented that it us similar to a loud speaker motor. They call the coil mag configuration a motor.    Pic below


Kind of the way I see things, the shorter path for a magnetic loop, the stronger the  field is. Without any cores, using a piece of plastic for the slider and putting the magnets at the ends would give the worst results. Once you add the center slider iron, of course the N pole fields will be attracted to it. With both mags in place, those 2 N poles now make that slider iron thee N pole. The field is spread out from each to the middle, and N field is available outward all over the 4 sides of the slider iron. But the S fields are free to go outward into space and loop back to the slider from all angles.

With just the 2 mags on top of the slider and 1 core piece on top, we have a similar situation and a lot of the S field is 'guided' closer to its destination, the N slider. So now the fields from S to N are shorter path and stronger.  The S outer core also attracts the N fields from the other 3 sides of the N slider to just the one side mostly. So you have a high concentration between the bars. As you add more mags and bars, you are encasing the coil winding in a strong mag field on all sides, like a voice coil of a speaker.  If you glued a hook to the center of a cone of a speaker and applied 1w, you may be surprised how many grams of pull you get. And the larger the speaker, you should get more pull with the 1w in.  About 2v for a 4 ohm speaker.

It brings back a thought on the guy on YT that added more magnets to the outer casing of a small electric dc motor and it was faster. Most skeptics argued that it increased the speed, but not the power out. But you device sort of proves them wrong I would say. More, stronger magnets makes for a stronger motor output for the same amount of input.

I tried adding neos to the outside if a toy motor and it ran faster. I have a few motors around to try and test the input vs speed/torque changes.

But according to what you show, the input should not change, right? I dont see why there would be much difference


About the outer core pieces, have you tried thicker ones and output was less?

Hi Mags

I'll explain how my design works.

A current through a coil of wire will produce a North pole on one end and a South pole on the other end.
Slide a steel core in the center of that coil and the coils magnetic flux will now flow through the steel creating the same poles.
If you add magnets on each end of the core, with each the same pole (lets say North). With a core that's longer then the coil, the North end of the coil will repel the North end of the core permanent magnet and the South end of the coil will be attracted to the opposite North end of the core permanent magnet which causes the coil to move from one end of the core to the other. Flip the polarity of the current in the coil and the coil will travel the other opposite direction.
When you think of it, both ends of the coil are being used to do work, which is good.
However, what many fail to see or are unaware of is, half way through a coils inner and outer thickness (winding layers) there is a blotch wall. So from the inside where the coil is North, a South pole will start from the coils half way thickness and peak on the most outer surface of the coil.
This is why when I add the outside core on the opposite poles of the permanent magnets now the outside opposite coil field is doing the same work as the inner part of the coil. This is also why the scales grams pull force exactly doubles when I add the first outside core.

So if you understand the above my design is actually using 4 sides of a coil flux and converting it to mechanical power. Also, my design has zero core to magnet sticking or cogging.  Actually, the stronger the magnets are, the stronger the mechanical output is and I have demonstrated this well.
I don't believe this is the case for standard PM motors as stronger magnets will not give you a boost in mechanical power.

Hope my explanation is clear enough

Now, if we can get my design to use TinMan's effect, I think we may have something good. That's what I'm interested in knowing.

Could you please indicate how the poles on the magnets are. Without that I'm not sure of how this works

Thanks

From what I understood about this, the armature is a carrier of the pulsed dc from 1 stator to the other...

Hi Mags
  The armature (rotor) and stators are not electrically connected in the RT. It would make no difference to the stator if the field was from a PM, or an EM.

Also, if you were to 'look' at the magnetic poles of the wired rotor while running, they will not rotate around the rotor, at least not all the way.

Not sure what you mean. The induced field in the rotor does rotate around the whole rotor - as it rotates, and the brushes move from one segment to the next. It doesn't move smoothly - it steps from one brush to the next - but it does rotate all the way around...

So mags on the rotor wont work.

Yes, that's why I said they had to be fixed to the casing.
