Hendershot motor
« on: February 28, 2012, 09:29:45 AM »
This user did a lot of work, but only with one side of the circuit.
This is a big file (take a while to open the link) scribd version
Basically there are two loop antenna (thought of Lidmotor and his am radio with loop antenna).  The coils are a basket weave, which decreases capacitance, and provides high Q by having a seperation of the windings the same as the wire size basically.  They are wound very wide (6 inches).  A 40uf foil cap is dismantled, and the 91 inches of 2 3/4 inch foil is re-wound on a 5 3/4 steel (ferrous, no mention of copper/aluminum/etc, a theory of operation is that it is stimulated by the rotation of the dynamo that is the earth's core, so it should be magnetic) .  Then there are a series of 3 other oscillator circutes directly related to one loop antenna, and then the same 4 replicated.  Then also two 1:5 transformers are used, asymetrically.   The buzzer should oscillate between the two, alternating generating voltage spikes as the flux makes/breaks contact.  Should think that the solonoids for the buzzer could be made solid state with something like stacked pnp's(?).  But then would I use coils there where the solonoid would have been (with a core?) or replace with a capacitor?
Since they are probably in slight distune, say by as much as 50-60hz, they generate  a voltage potential?  Could use some ideas with replacment parts for the solenoid part of this...

Sorry that was a horrible place to start, although interesting
Here he's testing his coil with radio stimulation. but that's not the point, he didn't have two :)
