Reciprocating Core Generator
#1
I am not the originator of this idea, but it is indeed an interesting concept.

If we take a ferromagnetic rod on linear bearings, and insert it into an inductor powered with DC, then move the rod core in and out (reciprocating) - the magnetic field of the inductor starts varying in intensity with each stroke.  This varying of magnetic intensity causes induction is a nearby coil.

When we short the pickup coil and watch the current draw of the primary while the core is in motion, we quickly realize that this method indeed can balance back-EMF similar to how a car alternator works.

Even though we are only using 1 polarity on the primary (DC), the output coil outputs AC with 2 polarities. And as the polarity changes in the output, so does the direction of Back EMF.  Thus causing a balance, which does not raise the input as we draw current.  On 1 stroke direction you will see the input current go UP, and on the opposite stroke you will see the input current go DOWN.  This creates a balance, if your strokes are balanced.

A possible configuration would entail 2 inductors per rod.  As one end of the rod is exiting an inductor, the other end is entering the other inductor. This would make it very easy to phase all outputs correctly.

Whether the residual magnetism of the coils will cause the rod to resist movement is yet to be seen.  But neither the inductor nor the induced have any physical movement and since a metal rod is attracted to either polarity the coil may be in, there is reasoning to believe "MAYBE" resistance to the physical motion may not be an issue.

We would probably have to think about eddy currents and I am sure there are other Snafu's that will be encountered, but this line of research poses serious possibilities and I would like to see it developed.

Thanks for the link.

There is no doubt the output can exceed the DC input that powers the inductors. This has been proven many times.   The question comes down to the reciprocation input requirement.  The proper design of the reciprocator would be crucial.
