Canceling Lenz's Law - Methods

[Magluvin]

Hey Marius

Nice setup.

I see the coil is in the middle of the center pole of the Ecore. Can you slide it closer toward the rotor and test?  Its that open side exposure of the coil that gets cut by the magnets field. So the closer to the rotor the coil is, the more flux that is able to cut it. Like if your core were say 6in tall, laying sideways as it is, the further out the coil is, the less output you should get.

Thats a big core. Try a smaller one if you can, where the core thickness is less between the magnet and coil. Or larger magnets for that particular core/coil.

As the rotor magnet approaches the core, the field of the magnet is attracted to the core, so as the mag gets closer to the core, the mags field bends more in that direction. So a lot of the flux from the mag may not even cut the coil because it is being absorbed by the part of the core that is closest to the magnet. So a larger magnet or a smaller core/coil will ensure more flux cutting the coil producing more output.

Sorry. One more thing to try.  Turn the core/coil, from the top view, 90deg so the coil is exposed closer to the rotor.

Hi guys!

Mags:

I did turn the coil as you sugested and there is voltage. More than before.
At 2000rpm there is 12V after the FWBR. A 450uF/50V cap charges up to 22V but not very fast (4-5seconds).
This is new to me:
-with a normal core-coil there is small difference at FWBR between the voltage with the cap or without the cap
-with the E shape core-coil the voltage doubles just by adding a cap.
My probe from the scope (mini-dso) is dead and cant see the waves.( Is more than a year that i'm looking for a new one but no one has it here in romania)
The bad news is that there is poor curent and lenz is still there, no mather what load is conected (even when charging the 450uF cap)

Dieter:

That's the only thing that I didn't try (the cap in series with the coil) but now is late and tomorow (like any normal working day) my weakup is at 4:45am  .
Things to try more:
-thiker wire
-bigger E cores (must buy first)
-stronger magnets

It will be nice if someone would replicate the E shape core-coil and see if the results match:
-relative normal output voltage
-really small curent
-and offcourse a bit of lenz

Magluvin,


The coil being near the PM is in fact a way to increase the efficiency. But with more efficiency comes also more braking lorentz force. Please revisit my prev. comment about the E core, deflecting the back magnetomotive force (being manifested as lorentz force), it is a fascinating thought! It does the same what the BiTT does, but in a motor! So, it's perfect, the coil pole facing the PM and the outer core legs far away from the PMs. The PMs may be a little bigger.


Gotta confess, I even don't know if this is driven by a pulse, like a bedini or adams motor, but for harvesting the output that doesn't matter, except maybe the PM arrangement: in a pulse motor it may be easier to use all PMs north pole outside, although alternating poles will increase the output and are standard for generators.


Anyway, you will bridge rectify the output and you should use schottky diodes (fast up to 1ghz switching, also low loss, low voltage drop). After them you should use a 100 to 200 v capacitor to harvest efficently any voltage peaks.


The reason why a Bedini motor is so effective is not the fwd current, delivered by the output coils, but in fact the rather high voltage back emf. The more sudden the pulse current stops in the output coil, the better the back EMF.


If pulse coils are separated from output coils then simply rectify the output. If the coils are used for both, you may use a schottky diode from the coil back to the source in parallel to your pulse trigger system, eg. reed switch or hall switch/Transistor combo.


If the system runs from a rechargable battery then these back feeded pulses may recharge the battery at runtime, although, in the Bedini system the charging battery and the driving battery should be separate units.


Anyway, thank you for giving me the inspiration for this E core Back mmf deflection, it's a fascinating concept. Have you been aware of it?
