Not really,

I went back and forth about which would be better, I couldn't decide if one would be better than another. I went ahead with alternating them for visual and there maybe a overall system stability thing going on. I'm not sure. I tried to think of a way to get a benefit from the forces between the pistons, but I couldn't.

What are your thoughts on this?

I'm just guessing but...
I think the distance between cylinders is determined by the greatest distance between pistons of the same cylinder (length of stroke x 2, plus the coil length plus the gaps between piston and coil). I think the pistons on each bank should be oriented the same way. First, we must get one cylinder running and then evaluate and move on.

Yesterday I received six free solenoid bobbins from Cosmo Corporation in Cleveland Ohio.I had asked them for a sample last week. I phoned Ian Coke-Richards last night and he is going to use these bobbins to wind three coils for me. We also discussed using a mechanical commutator rather than the Hall IC. I have completed the motor except for coil and electrical. I will be gone 'til Monday evening.

Peter,
  Hi!  I have been looking at your link on your reciprocating magnet piston engine. I would like to duplicate it, if that's alright with you.  I need to know the magnets you used and the size of the coil, and what power supply you used.  I have done some experimenting with pulse motors and like the reciprocating type motor. I also would like to eventually experiment with the back EMF.  But, I figured I would start at the ground floor (so to speak).  Any help would be greatly appreciated.

Hi Howard
So good to have another builder to compare notes. Most of the info can be found at http://www.eebeh.com/opm.html
The magnets are 3/4' x 1/2' Neo cylinders; the coil is 1.125" Length x 1.125" OD with a .385" ID with 24 gauge or 26 gauge wire. I have two power sources; a 12v and a 6 v sealed lead acid battery so I will try 12v or 18v. Do you have access to fabricating or lathing and milling equipment? The crankshaft posed the greatest challenge. I will be relying on my friend to claim the back EMF which is my eventual goal. If you need specific info as you build, just ask.

Peter,

How do you hold the permanent magnets in the piston heads without them coming out?

Peter,

You drill a small hole in the back of the delrin magnet holder (piston), you press fit the magnet into the piston and if the piston is machined to the right size it will stay. If not add some epoxy glue.

Okay Howard
How is your duplication coming along?  Any help would be greatly appreciated.

Thanks, that is interesting. The drawings above were made by me of Tropes design, that's not my design. Although my design can be found here:

Hiya Tropes,

Hope everything is good with you. Have you started working on your design again yet?

Best to you.

 That is the design I was talking about. It is very interesting and it could work if a couple things were changed and if couple of things were added it would be more powerful and more efficient.
 The sleeves that the pistons move in could be used to generate electricity and the coils could be wired in a series so that they run off the others EMF and collapsing fields using capacitors.
 The coils should be used to draw one side and repel the other so the cams go in the same direction. Meaning, when the coil fires, one side will draw and the other would repel. This would utilize both coil effects.

 I would like to see one built because I think it can work but then again, I am no physicist or scientist but I am a auto mechanic with 25 years in the field.

Yes everything is good. Sorry I can't contribute to the forum at present.

I went around about which would be better, both pulling or being opposite. It turns out that when you pull from both sides at the same time, it cancels out all induction, I think that's is a good thing.

I agree with capturing the collapsing fields and capacitors to feed it back into the system, I addressed that in the "Magnetic Force" paper.

Putting coils around the sleeves is brilliant. Good for you.

This would make a great motor just for the extreme torque, but my hope is that it is overunity. Gaining the difference between the pull of the magnet compared to what it takes to release the magnetic grip is where the gain appears; I think that it may be necessary to create only enough current to just ?release the grip? and not going to the full repel. I?ll think some more about this.

The hardest part so far is coming up with the crankshafts. I looked into some old cranks from outboard motors, but I could only find ones that have three pistons. Cranks from car engines would be too big. I talked to a number of crankshaft people and they all said that with the forces involved, one would have to overlap the crankshaft center shaft with the shafts that attach to the pistons. With the Magnets in my example, one would need about a 3 centimeter gap between the electromagnet and the permanent magnets.

I really can?t say this would be overunity, but it would be an awesome motor.

If there is anything I can do to help, let me know.

rukiddingme, I thought the added power from having both the repelling and attraction would give the motor twice the power. I also thought the EMF and or collapsing of the switched polarity would just add that more energy back to the battery's. At the same time, I thought it would recharge both having one polarity feed back charge one and the reverse charging the other.

 Have you thought about using hollow core electromagnetic coils? Or maybe even just using a very thick walled steel bushing for the core having a hole it the middle to attach a rod from one magnetic piston to the other?
 I think that would alleviate the compression from the attraction giving you more efficiency as well as more power. Although, using a o ring seal between the core and the rod connecting the pistons go would make for a interesting air compressor by using one way valves, one for the air intake and the other for air out to a holding tank. It would be interesting to know what kind of compression could be achieved.

 As for the crank shaft and rods, I do believe you will have to have them custom fabricated based on the throw and or attraction distance. Then you will also need to know what the least amount of attraction and or push you will need to have to get your over all HP needed.

 I think the compressor idea would be good as a testing stage as well as it would be a great invention for that field if it was to produce enough to be usable. If it was to work, it would be worth millions just as a air compressor. Think about what air pressure is used for.

 Over all I think you have came up with a good design. Good job and I hope you continue with building it. If you build the air compressor version and it works and makes you millions, don?t forget about me. LOL
