Motor Generators

Fake news BroMickeyLier:

In the 6 minutes of the video, the battery goes down from 67.0 to 66.5V. And the 10.5A on the amp meter is the charging current to the battery. Thanes conveniently doesn't measure what the current from the battery to the motor is. This is a very easy measurement to do and should immediately show if the battery charges or discharges overall.

And btw this is an old video that was already commented on extensively by bistander and myself.

Happy New Year. Hopefully next year you will post some true stories. Have you considered going to work for the fake media?

Driving Time Duration = 16 minutes. Ebike Speed = 29 km/hr EV "distance travelled" = approximately 7.7 km. INITIAL EV battery voltage = 74 Volts FINAL EV battery voltage = 73.9 Volts Battery Voltage Consumption = 1 mV Ebike Recharge Rate = 99%

Normally the ebike's battery voltage always drops slowly even in Regenerative Acceleration Mode - due to generator coil core losses.
However the ideal combination of ReGen-X Quantum Motor coils and ReGenX Generator coils produced a solid 16 minutes of continuous running at 29 km/hr and the battery voltage did not drop and stayed at 67 Volts and it looked like it was going to increase to 68 Volts.
It took me 10 minutes of waiting to see what the battery voltage would do before I realized I ought to pick up the video camera and record what was going on...

Thanks Bistander, ... so to work the homopolar generator the magnets must remain fixed or turn with the copper disk? ... I saw that in the De Palma experiment the machine built by them had the magnets on the rotor together with the disk of copper, and they were all spinning together, and that's what I tried to replicate but without useful results, nothing to do with the De Palma generator.There are 4 brushes for each pole, of the carbon type which are used for electric wheels measuring 16x6mm.

" so to work the homopolar generator the magnets must remain fixed or turn with the copper disk?"
Yes.

First you need to generate voltage. Requires complete flux coverage, uniform and unidirectional, over copper disc.

To get high current, you need very low resistance electric circuit. Carbon brushes offer too high resistance. Use very low resistance everywhere. Brushes especially. Try straight copper metal at first. Will be low resistance but poor wear. Once working look into high copper content metal graphite brushes.

[a Lenz reaction is generated. even at very low revolutions, trying to rotate the disc with your hands you feel a strong resistance. I also tried to offset the magnets, but there is always resistance, even if a little less.

P_20211127_121027.jpg P_20211201_171047.jpg I also tried to spin only the copper disc, putting a single pair of fixed magnets, on aluminum supports, but the motor is not there because an excessive braking force is generated, obviously a Lenz reaction is generated. even at very low revolutions, trying to rotate the disc with your hands you feel a strong resistance. I also tried to offset the magnets, but there is always resistance, even if a little less.

Hi Memphis,
Yep, with those set-ups you make an eddy current brake. To get the unipolar (or homopolar) DC generator you need a 'uniform' magnetic field covering the entire disc area.

That's a pretty neat 12 pole synchronous PMAC dynamo. Memphis is working with a Faraday disc, homopolar, DC dynamo. Note the multipolar unit rotates the magnets adjacent to the stationary copper disc. Memphis rotates both the magnets and copper disc, essentially having no stator, except for the brushes.

Faraday's Paradox. Interesting. Look it up.

Bro, from the video it seems to me that the meter is set to amps, it is only 0.5A

thanks Bistander, the magnets are arranged to attract each other, NS NS NS with the 2.5mm thick copper disc in the middle, I tried to rotate the disc at both 1400rpm and 2800rpm, but the result is almost the same , the increase is minimal.

good morning guys, sorry if I allow myself, I know that this is another question, but I wanted to hear your opinion about it .... I tried to replicate homopolar generator, I used a copper disk with a diameter of 33cm, and 6 cylindrical 52n rare earth magnets measuring 6cm x 3cm, mounted in pairs on both sides of the disc and inserted in those nylons plates that you see in the photos to keep them united and integral with the disc of rotating copper, I turned it into rotation at 2800 rpm, I used 4 carbon brushes on the 2 inch diameter copper shaft and 4 brushes on the periphery of the disc, but the result was very disappointing, as you can see from the photos , not only the very low voltage, but the serious thing is that the amps were almost non-existent, we are talking about 0.2-0.3 amps ..... why? does anyone have an opinion about it or should I conclude that it is another fake ....?

Hi Memphis,
interesting project. Nice prototype.

Are your magnets arranged unipolar or N-S-N-S-N-S around the disc? How thick is the disc? Air gap (distance between magnet faces)?

Describe the brushes please. Where did they come from?
