My current ALF build log

[Jim Mac]

trying to think through it... will take me some time. To write down a timeline of parallel events or something may help..

Ok here is a simple sloppy sketch.

   

A rotor has coils that rotate.  AC feeds into the coils with sliprings and brushes.

The motor needs to rotate IN-SYNC with the AC going into the coils.  This means you can now position the coils at Any Place to interact with the passing AC wave (magnetism).

Now the output coils shall be placed exactly where dead center of the passing AC wave is at Zero.  This should cause a Lenz Reversal where the magnetic field Shrinks on the way in and Grows on the way out.

Hey Jim, yes, I see, very interesting.

Here's an update on my progress with my current ALF build. "The law" wasn't debunked definitely so far, lol, but htere is some progress and some importnt conclusions drawn, about what needs to be optimized further to get highly conclusive tests.

So this is part 5, testing whether there are audible speed differences, depending on 2 diode directions and circuit-closure vs open circuit:

For those who are unfamiliar with this concept, I suggest you read my pdf ALF in a nutshell:
https://odysee.com/@HRMofUtopia:4/ALF_in..._4odysee:4
And an appendix about a way to reduce the cogging by means of multiple phases (like also in this current build)

Here's n animated FEMM simulation, which shows how the reverse field-strength to distance ratio is achieved:

With this information you'd understand all my remarks in this 2024 build video series, currently part 1 to 5:

Hopefully this will be useful for somebody, maybe somebody with better engineering skills and abilities would progress faster - whether to the point of the postulate being debunked, or to the breakdown of "the law" lol.

Still working on it. Got a new test drive motor, more suitable than the last one, also currently building a new rotor. I am testing a design in which I wrap an iron wire tightly onto a cylinder, basically like a coil. It's got a green thin cover, so the turns are isolated from each-other. Then I put it into a rotor casting mold (it fits perfectly) and submerged it in epoxy resin. Now I only have to saw away the spaces between the bridges (then fill these gaps with resin too). It's a kind of lamination, although not sheets, but wires. If I had a punching press, I'd make real laminates, however I haven't. I thought it's worth a try, considering the relative ease of construction. I'll let you know when there is a new video.

I am pleased to hear you are still working on it.  I still think there is potential in this idea (if we can manage to get the parameters right).

Absolutely. I am trying to debunk myself since 10 years plus. Without success so far. It is not clear however, whether the shared core of PMs and Coils ruins the concept. My first, somewhat successful test (acc under load) was with  a non-shared core design. So I may go back to that design, but we'll see.
