Kromrey Noise

Here is an audio clip of JB's Kromrey demonstration at the 1984 LA "Town Hall" meeting. This was a larger machine running a string of incandescents as a load, through very thin wire which stays cool....

Magnetostriction

I have been researching magnetostriction, starting with the usual mainstream sources, in a quest for what might be the best material for the Kromrey magnetics. While we won't know what exactly JB...

The two rotors are connected via a hole under the slip rings. All rotor coils are connected in phase adding, such that the peak voltage is maximized by series addition of the four individual EMF's. ...

Yes, I have seen some of the delayed Lenz demonstrations at very high rpm. But Kromrey's test data shows quite low rpm's with his large machine. Also, JB's original large replication shows loud...

The Plot Thickens

I tested my latest version of the Kromrey, now with pole pieces and stacked magnets as used by others. I used about 210 turns on each of the four coils, #26 or close to that. My rotors are 25mm...

You are right in that this type of core is designed not to have remnance. A better toroid material would be to try a tape wound square loop type of core, which were used in small inverters in the...

Comments based on Aaron's recent video

Aaron's recent video of JB's miniature Kromrey generator thankfully included the output waveform. The voltage showed what would be expected from a conventional salient pole induction generator,...

More on pole pieces

Another reason why large, massive pole pieces could be crucial to the Kromrey is due to the inductance modulation effect. As the rotor cores come into alignment with those pole pieces, the coils will...

Some more thoughts on windings

Below are a few thoughts based on what I have seen so far with my experiments. Aaron has made clear the pole polarities on JB's unit, the same as the German unit from Jens Vogler, are as shown in...

That depends on the switching frequency and the permeability of the core material. I would guess that they were using something in the range of 50kHz-100kHz. If the core has high permeability, that...

Yes, it looks that way to me.

It will vary the pulse width of the drive signal. Wider pulse, higher voltage output.

Those very low value R's are needed to balance the currents in the paralleled...

First tests

My antenna measurements turned out quite similar to tswift. Using the latest circuit, 5.4.7, it is clear that the spark gap requires voltage peaks coming from the antenna in order to fire. This is...

What you will see mainly is 60Hz and its harmonics. So some form of high pass is needed to get rid of that. Most of the noise I see is actually at the half wave frequency, a bit above 900kHz, as that...

Antenna tuning

I have a long wire strung up through the trees, over hill and dale. It averages about 3m off the ground, but is less and more as the terrain varies.

I tested the resonance of the wire against my...
