Opposed Piston Motor

[tropes]

You say that it consumed .875 watts.  Was there any A occuring or was that a calculation of (input power - output power)?

There is always power induced by the pistons moving towards the coil so I keep a small fan motor running while the motor is running.

Why not feed it into the battery that you're running the coils with?  Better yet, put a generator on the crankshaft.  Mattering on the size of the generator and the draw that you put on it, you might be able to get more out than you're putting in.  From what I can see, you've got a decent pull on that crankshaft - at least a couple of pounds.  If you have 2 pounds of force and we're talking about a 1/2" radius with 1200 RPM, that works out to 20 * 2/12 foot pounds/second.  I might be wrong about the calculations, but the kinetic energy that you're talking about is approximately 5 foot pounds per second.  5 foot pounds/second works out to 7 watts worth of energy.  Of course, this is only if you can maintain the 1200 RPM while putting a load on the crankshaft.  If the draw remains the same, as long as you can keep your RPM over 200 RPM, you should be able to have it self-run.  I think that your RPM will drop, but it's hard to say how far it will drop.  If your pull is 1 pound, then you have to keep the RPM up around 400 RPM to have it self-run.

Using the basic single coil Sotropa Motor http://www.youtube.com/watch?v=_YOHSOK5kU4 I have hooked the induced current back to the source battery and have not had good results. By going to a capacitor and  regulator I found that I could use the 2.25 watts (.5 amp x 45V) to fire the coil 4-5 times using a SPDT switch.
Once I get the 5 coil motor running again (replace the broken rockers) I will use the capacitor to fire a couple of the coils.
You say this is not the most efficient design, so how do you think it could be improved?
As far as a patent, by making my work public I am allowing anyone to construct and improve this motor.

How would I make it better?  I would get rid of the load (the flywheel/crankshaft) during the repel phase.  There are a few ways to engineer it, but you're pretty clever and I think you can manage it.  Actually, you might be able to do it in a more clever way than I would - you're the only other person I've seen here who has come up with a design that isn't identical to 900 other designs that don't work, but somehow claiming that you can get it working.

Clever is often not enough. As an old drag racing engine builder I find it difficult to get past the flywheel connected to the crankshaft connected to the piston. Your engineering thoughts are welcome.
