Zen Generator - A No Back Torque Electromagnetic Generator

[hartiberlin]

Hi Vidar,
many thanks for your test.
Please supply your whole calculations, so it is getter clearer.
Many thanks.

P.S: These devices always rely on very specific materials,
so it realy depends heavy on the used magnets and toroids
and coils and magnet flux paths..
The slightes modification can have totally different output results,
so a quick setup with the wrong type materials will not result
in a success...

Regards, Stefan.

Well, there is actually no spesific calculations others than the resistance of the wire, but the tests have being done this way:

Equipment:
Small toroid. Outer diameter:7mm, Inner diameter:50mm, hight:30mm
Two 5mmx5mmx50mm neodym magnets polarized across the length
Drill
Plastic insulated wire

The building:
The wire is used to make the coil which is a double layer @ 25mm length. Approx 30 turns.
The magnets are fasten directly on the steel chuck.

Now, the drill is running while I'm closing the distance between the toroid and the spinning magnets. If I get too close, the iron in the toroid will be saturated - which is not what I want.

A Fluke AC-volt meter is used to measure the coil while the magnets are spinning.

Regarding the calculations done when the coil was loaded, I measured first the voltage with a known resistive load. The calculation concluded that the flux density around the coil was reduced when the coil was loaded. As the voltage did drop much more than the wire resistance should promise, when the coil was loaded, the flux density must then increase on the other half of the toroid. This will in turn virtually make a higher impedance in the generator, as the fact is that less flux is running through the coil when it's loaded - hence the dramatic voltage drop. I will apply pictures when I get home, but here is a drawing of the setup.

Maybe
You should use a slotless motor of 2.5 hp or larger as the smaller cores have an inductance that is very high and the terminal voltage will drop as you load it.

Maybe a 2kW toroid should do... $150 - 200 I guess

Hey! don't tell me you don't know that all this f.e experimentation does come at a price. But if you are ghetto like me. You build the stuff you need. Takes longer I know but it's cheap. Here is how I made that core. It is build from a burned out 15orso kw motor. I cut the core in half, and removed the fingers from the laminates then re-insulated the laminates and put the thing back together. And viola a big ass ring core is born. And it did not cost more than like $10 - And I only used half the original core.
