Hi all
I placed a coil around each piston and joined the coils together. I rectified the current with a diode on one end and am able to measure the generated voltage.

hi tropes,
i saw ur vid...good 1...putting some coils on those pistons.
2.6v is a good start...
what about putting some magnetes on the piston...in speakers u can find nice round magnete that maybe u can fit nicely on those piston.
magnete going thru coils...u know what that means.
more generated volts...at least thats what ima thinking.
Peace!

The pistons are magnets. That's why the coils are generating a current. That's what makes the motor work: the magnets attract and the coil repels them.

Yes they are neo's.
1 1/2" dia. x 3/4" thick
Material: NdFeB, Grade N52
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Axial (Poles on Flat Ends)
Weight: 5.75 oz. (163 g)
Pull Force: 177.25 lbs
Surface Field: 6985 Gauss.
As far as voltage, I have filled the capacitors with over 60 volts using the generating coils and the bemf. Producing voltage is not the problem with this motor. How to use it is.

So I wrapped about 3000 ft. of 30 gauge wire around the pistons.
At about 1250 r.p.m the coils generate thru a FWBR 35 volts but only 40 milliamps.
So I will try using a thicker wire (24 AWG) to get more amperage.

hi there tropes,
u r making good progress there...nice pics...keep it up...:)
thicker wire and less turns/windings will get u more amps.
btw...is that a flywheel u got there on tha front...if so...nice 1...yeh ima need 1 2...more momentum...:D
4got...is tha 35v from 1 or 2 coil?
and if its from 2 coil r they in series or parallel?
Peace!

Yes that is a flywheel with a piece of reflective tape to get a tachometer reading.
The 35V is from 2 coils in series as per the earlier response to Rob post of 03/05/2009. It was actually Rob who suggested I use a FWBR rather than a single diode.

1 question tho...looking at ur pic i see that the right coil is fatter than the left 1...so does that 1 have more windings??

Yes, the fat one has 2637ft. of 30 gauge wire; 293 ohm. and the other has 333 ft.; 37ohm.
I have observed an increase in RPM when I add the coils but when I use the generated current to run the fan the RPM drops.

I don't think the wire size makes any difference as far as generated current. My present measurements are 35V and .06 amps = 2.1 watts. If I use the same weight of thicker wire I will get .6 amps but only 3.5 volts. Still 2.1 watts.
Maybe an electrican can help.

Quick rule of thumb.
The thicker the wire the more currant.
The more wire the more voltage.
The above is correct to a point.
If you have a very long winding you will get good volts but not so good courant, so one would think from the above rule of thumb one would have to just rewind the coil with the same length of wire but with a thicker gage, well not that simple.
The more wire one uses in the coil the less currant but more voltage. (It’s the balancing between length and gage to get the required results.)So in short to get more currant you need low coil turns but thicker gage wire.
Just have a look at a car alternator gage of wire, you will find it’s thick gage wire and low in the number of turns in comparison to are work.
The next thing is in order to calculate a gage to length ratio for any alternator one would have to know all the dimensions of your proposed alternator, like the materials its going to be constructed from. The type and strength of the magnetic field that one would be using, and a bunch more information would be needed to even start.
In other words it’s a mind field when it comes to Alternators/generators.
So that brings me back to the Quick rule of thumb.
And the above is correct to a point.
Alternators/generators may seem very simple when completed but not so when preparing to build one from scratch.
Nice work Topher. I may seem to be absent, but I am watching all your progress.
I’ve gone back to playing with magnetic motors just for now but nothing to report.

Thanks for your input.
Unlike the thousands of John Bedini and Robert Adams replicas, there is only one Sotropa Motor. Likely because of the ease of construction of the Bedini type or the dislike for reciprocating piston motors. Fact is 99% of vehicles built are powered by a reciprocating piston engine.
I believe a reciprocating piston type electric motor would be well received by the public.
I have all parts required to complete a five coil “Sotropa Motor”. I believe that the current generated from four coils will power at least one other coil. However, I am in need of a fabricator or manufacturer who is willing to trade their time and expertise, and perhaps a small amount of material, for the time, expertise, and material which I have contributed and share the final product. This fabricator/manufacturer must have the facility to assemble a crankshaft and the engineering ability to construct a frame in which to hold the motor. Are you listening GM ?

The FWBR converts AC to DC. The two ends of the coil wire are connected to the two AC input leads of the rectifier. The current goes though a series of diodes to create an output of DC (positive & negative). The output voltage can be measured by attaching the multimeter to these two output wires.

that ima can follow...
but its the current that is abit of a pain...
i can messure the current that ma setup draw...
but from like the 6 GC that i have or the generator with prop...still have 2 learn that...
but...that doesnt keep me from pushing forward...:))

Thats just so unfair...
Last night i found an old RC nitro engine that had a score down the piston liner (hence why i couldn't use it) and i thaught about sticking one of my neo's to the top of the piston and putting a coil where the piston head should be...
And then i had the thaught of building a 'V8' pulse motor... but as mentioned, the crank shaft could be a problem...
I can in here to post my thaughts only to find this topic... DOH!
Someone with a lathe/CNC could proberbly do one...
For the rest of us mere mortals my only thaught was to use a mold and epoxy...
Any ideas?

As an old drag racer from the 70's I had some of those same thoughts.
Some of my early work including a single piston motor can be found at http://www.theowlnest.com/hopgy.html
I came to the conclusion that the most efficient motor was one that used one coil between two magnets; you get the attraction of the two magnets for 180 degrees and the repulsion of one coil on two magnets for a short duration. The drag of cylinder walls is eliminated because there is no need for compression.
I now have all the parts(40)for a 5 coil crank which I hope to assemble soon using Loctite. The staggering of each throw is tricky because of the firing order. I would very much like to see another piston motor being built by someone in this group.

Indeed that does make it more efficient...
However, wrapping a gen coil around the pistons is not going to work too well since you'll still have the lenz drag...
having said that, if your piston tubes were thin steel, then theoretically you could draw a limited amount to power without additional drag on the pistons because the lenz flux would be able to flow through the steel to the other side instead of acting againsed the magnets on the pistons...
I wonder how many piston pairs would it take to spin a small alternator and then, how much could you get out of that alternator...

The Lenz effect does not occur until the current is drawn from the coils much like a solonoid. However, when the current from the generater coils is used, there is a breaking effect (lower RPM) on the motor. I hope to use this effect as a means of charging a battery each time there is a need to decelerate.
The cylinders are made of two graphite rods rather than a steel tube because there is less drag and the magnets would be attacted to the cylinders if they were made of ferrous material.
The flyback voltage from this setup is collected in a capacitor and I believe that with a 5 coil motor I will be able to fire one or two of the coils from this source.
It is a pleasure to have your input and interesting views on this unique motor. Thank you.

Great work, very nice motor.
I'm curious whether you've managed to come up with a way to use the juice from the cap you were asking about earlier. Didn't see anyone reply to your question about it.
