Opposed Piston Motor

[rukiddingme]

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.
