Confirming the Delayed Lenz Effect

[gyulasun]

Hi synchro1,

If I got you correctly, you rotated a diametrically magnetized cylinder magnet (fixed axially on ceramic bearings) by a bifilarly wound coil. And a reed switch connected in series with the coil insured the correct pole should appear to the coming magnet pole and here I assume a simple attract mode?

This is very interesting because even if you had no output coil, the mass of the rotor magnet obviously needed work to maintain the 25k rpm while you noticed the current draw dropped to zero.  I wonder if you can repeat this test any time or it was a single phenomena?  IS it ok to consider a zero current draw indeed or it went down to the some mA range versus the some ten or hundred mA draw while speeding up? 

Thanks,  Gyula

I wound a thread spool with a bifilar wrap, series wired, and powered a 1/2" diametric tube magnet on 1/4" ceramic bearings. The coil was wired in series to a Reed switch and a 12 volt 6 amp hour Radio Shack battery and an amp meter. I Laser tached the reflective tape marked magnet spinner. At 25k, a burst of speed developed that practically doubled the r.p.m's while the amp draw dropped to zero. I called this effect Lenz propulsion, and developed a theory. No output coil was present. What's this say about a baseline?

Hi synchro1,

thanks for posting your interesting result. Could you post a video to show the burst effect. Also a picture of your setup would be helpful.

These are pictures of perhaps the World's first Internaly Motorized Alternator, minus the output wrap.

Left to right:

1- View of the 3/4 inch spinner in the 2 1/2 inch PVC core.
2- Miniature 1/4 O.D. , 1/8 I.D. all ceramic bearing on top of a Radio Shack 12 volt 6 amp hour battery.
3- Position of the 12 volt Reed Switch on the Hi Voltage Spool Coil. Pins should point away from the magnet..
4- Top secured for runing with coil seated down partly inside the output core.
5- The six main componants: Power coil on core, 1/8 inch brass axel, ceramic bearing, battery and Reed Switch and 3/8" diametric tube magnet.

One thing i've been pondering.

The 2LB coil i wound (bifilar/series), when shorted and presented to the rotor caused the following changes to frequency and input current :

Frequency : Dropped from 486Hz to 482Hz (0.8% drop)
Input Current : Rose from 410mA to 413mA (0.73% rise)

This coil was producing 4.2 watts of power (measured by DMM and analogue meter) to an incandescent bulb load  and caused very small changes to rotor speed and input current.

Presumably two such coils would cause around a 2% drop in RPM and a 2% rise in current draw and give us a little less than double that figure of 4.2 watts, lets be conservative and say that two coils output 8 watts of power or even 7.5.

The input to the rotor started at 18VDC @ 410mA = 7.38 watts.

Still waiting on my perspex parts, they should have arrived by now.


Cheers,

Hi DC,

good experiments you have going.
One thing I noticed is, the lower the resistance (load) on the shorted coil the less effect it has on the prime mover. You mentioned you have a bulb as load. That may go up to 10 ohms or more when lit. Try a 30 watt 1 ohm resistor instead. The coil may now have zero effect on the prime mover.
Let us know how that worked or if I have misunderstood your test.

WOW, that was fast!... thanks for the pictures synchro1

Could you do a video demo?

ADDED: just noticed you added other pictures, thanks that helps. I'm interested as to what the CD's are used for.
