Opposed Piston Motor

[tropes]

   Sadly, you are stuck with one per coil. Cant see any way around that one.
If you used mechanical  contacts, you would still need a set per coil to turn
it on and off at the prescribed time. Just the way of it.

I suspected that.I am sure however that I will be able to reduce the duration (opening in the slotted wheel) to about 17 degrees for each coil for a total of 80-85 degrees. The beauty of the opposed pistons is that 180 degees of rotation is generated by the attaction of the two magnets. This axial force is greater than the tangential attraction of a round rotor.
The collection of the BEMF is a simple matter of attaching a diode to each coil wire.
I hope someone will undertake to construct this motor and share their experience. Working in a vaccuum is the shits.

Hello Tropes,

when I saw your posts here I remembered this paper of Aspden ( Potter-Debate ) :

Keep up your good work

Thanks for the great info. The Energy Science Report N0.4 is one of a very few documents which examine the value of a reciprocating magnetic electric motor. Adams maintained that his motor was an attraction motor and realised the value of using magnetic attraction as a " free force".
What I have not found is research done where Faraday's Law and Lenz's Law are applied to 2 attracting magnets moving towards a coil. Perhaps because of the lack of strong Neo magnets, it was not realized that a strong attraction was possible even when separated by a coil.
Thanks again for the valuable report.

Since I was not able to find any info. regarding Lenz's Law using two opposing magnets, I did an experiment using magnets and coil on my motor. I posted the video at

Why don't you set up 2 piston sets (one on each side) for more consistent torque?

Also, I would probably go with a nice planetary gear set to spin up the rotational speed - probably a 10x gear, so you can run around 600 rpm, spinning up to 6k rpm.  They're only 95% efficiency, but that's way better than any other chain/gear set you'll find (between 85 and 90% efficiency, if you're lucky).
