Flynn PP Motor Idea

[Drak]

Ok here is my idea for a Flynn Parallel Path Motor:

http://www.darktruths.com/flynnidea.avi

  Any Ideas on how to improve on this?

  I'm sure you all know how the Flynn demo device works. I have tested the Flynn device and it does work as specified. The wheels are non magneticly attractive (wood). The metal pieces on the wheels however are magneticly attractive. As soon as a metal piece gets to the point of pull back on one wheel the polarity on the Flynn device is reversed and the metal piece on the other wheel is pulled in. Then the process is repeated.

  Adding more devices to the system (as in the animation) should do what? I'm asking because I don't know.

Drak,

I really like the concept.  Excellent animation.  I think it would be a good concept to build on.

Adding more devices produces more torque, and potentially smoother torque.  Llike an 8 cylinder motor vs a 1 cylinder.  You have more points in the rotation where you are adding torque to the output shaft, which gives smoother power.

From a mechanical standpoint your concept would have to be altered to make it strong enough to hold up to the forces.  Your rotors as shown would just bend together and stick to the stator if the stator were spaced in close proximity.  Conceptually I like the idea.  I would consider it a worthy candidate to develop into a prototypeable design.

I think it is one of the more exciting concepts I have seen.

If you want help, let me know.

Hi Drak,

Very good arrangement of making Parallel Path principle work as a motor and I also agree with Jake on the mechanical needs (though in the animation they do not matter of course).

Some thoughts on the practical side:

1) I would not use the metal pieces but (rectangular) ferrite pieces instead, to avoid eddy currents in the metal pieces. The ferrite pieces could be obtained from burnt-out line output transformers used in televisions or CRT PC monitors and maybe freely given away in repair services/shops. Or in the lack of ferrites, normal mains transformer laminations could be used.  These could also be embedded/glued into the rotor body.
2) To sense the moment when a polarity change is needed, a Hall sensor could be used that would be triggered by a small permanent magnet glued to the rotor at an appropiate place.
3) The polarity change could be done with the known H bridge, using either bipolar or MOSFET power transistors.

Of course many other practical issues can crop up and many solutions exist for them, the above three suggestions are the ones that suddenly occured to me as maybe important ones for a start.

 Jake,

  Thank you!

  (in theory) Do you think it would increase effeciency? Flynn PP is supposed to be 400% (I only see it at %200...anyhow). So adding another device make it 800% then another at 1200% ect.. Or would it just stabalize the %400? With one device I have 2 extra power from the P-Magnets. With another device I have 4 P-Magnets powering the device, then 8, then 16 etc..

From a mechanical standpoint your concept would have to be altered to make it strong enough to hold up to the forces.  Your rotors as shown would just bend together and stick to the stator if the stator were spaced in close proximity.

  Yes you are correct I have dealt with that problem before. I can't seem to find a metal stabalizer piece that I can bolt the wood wheel to (not sure what its called but I can see it clearly in my head). The only wooden way I can think of to fix this would be to use wooden pillers say 4 or 8 of them going from the inside of one wheel to the other "ECK!". Or a 2X4 and bolt each wheel to it and drill a hole in the center, lol.

  See jakes reply above.

  Hmm, ferrite pieces? Can these things be ordered at a specific size? Do they have more, less, or the same attractive power as soft iron laminents? Laminents were my first choice because they are easy to work with. Is eddy currents the only advantage of ferrites? I never thought of ferrites.

2) To sense the moment when a polarity change is needed, a Hall sensor could be used that would be triggered by a small permanent magnet glued to the rotor at an appropiate place.

  Thought of using a reed switch, but wouldn't you need a magnet that is exactly the right sizie in order kick it on and off at the right time? I was thinking more along the lines of a light senser. Use another wheel with notches cut out in the right spots to allow the light to pass throught at the right time, kinda like the old mouse wheels used to work. Is a hall sensor the same as a reed switch? Anyhow a hall sensor or a light sensor would be better to reduce drag of a physical one.

3) The polarity change could be done with the known H bridge, using either bipolar or MOSFET power transistors.

  Ok now you are getting into the stuff I really need help on. I was just going to use a solid state relay because I don't know anything about MOSFET things. Well, at least wiring them up for a polarity change. I will google that and see if I can find a schematic of how to use that..Thanks

You will ever stay (C8-ceramic magnets related) in the
400% range !
But you can also change the output-power through
3x/4x...wheels use !
