'Core Rearrangement' - 'Fin Motor' - Open Tech - OU?

...When I look at your drawing I see one pole getting enhanced and the other being diminished.

Hi Webby,
I think the main coil's effect will be to make both poles 'disappear' as the core becomes saturated by it. I don't think it should enhance one, and diminish the other because the fields are perpendicular to each other...

BTW, I've decided I need to do more tests on the fin-motor design - but using longer fins, that don't overlap when it's unpowered...

I think the flat, semi-circular fins are too thin, and I think Gyula was right, and there is a shielding effect of the central fin by the outer ones...

I'm going to try it with 1 inch long pieces of 12mm round mild steel bar...

Update:
- I cut some 12mm mild steel round bar into 20mm lengths.
- I fixed 2 in place at the ends of the coil - as stator pieces.
- I held the central rotor piece by hand
- When the coil was powered, the rotor was attracted strongly to the stator pieces.

Conclusion: Long pieces of iron make better magnets. 

Diagram attached. This is my current working model for the Fin-Motor - although it doesn't really have fins any more - so I need a new name...

I still think the basic principle is a good one. I'm just trying to get the tools I need to build a prototype...

Hello Tim123.

It amaze me how fast you improve your system and have new ideas to go through the problems you meet.

Good work!

Have you stuck a magnet on the end of the stator pieces yet?

As far as 90 degrees goes,, Franken Motor used that arrangement very well,, O.K. the magnets were in pinch, or stress field, mode but still,, they pointed 90 degrees to the coil and core.

..I don't know but I do know that a motor can run for very little input that way,, not much output however.

Hi Webby,
  Not sure if this is what you mean, but for the motor to rotate with the coil in a tuned-circuit, I think magnets would be needed as shown in the diagram below.

Franken Motor. Lol. good name... I found it - it's interesting...

The output power of the fin motor will depend mainly on the size of the rotor / stator poles. More surface area = more power. Max force between two 1m2 magnets is 100 tonnes...!

Hi Khwartz, Thanks!
