Working Magnetic Motor on you tube??

[blue_energy]

@Yadaraf,

"Q:  If some one can explain why there is a 20dB increase at 172.3 Hz after the rotor accelerates, I'd appreciate it. "

Could it be that that's the stator bearing after it's latched at AGW rotation? When I get my rotor back (on Thursday, hopefully) I'll send you an audio sample with the stator latched in AGW rotation (not difficult to achieve after applying penetrating lubricating oil) to see if there would be such characteristic frequency at all, and whether or not it would increase after the AGW latch.

Omni,

I think you know this, but bear with me.  The left series of graphs is the result of sampling with three stators rotating -- with the primary stator latched AGW @1700 RPM -- right before Al stops two of the stators.  After Al stops two of the stators, the device accelerates, and both the rotor and stator increase in speed as observed in the freq shift from 839.8 Hz to 861.3 Hz.  The right series of graphs is the result of sampling at the very end of Al's video.

During acceleration and the 839/861 freq shift, the mode at 172.3 Hz remains fixed, but is amplified 20dB (a linear factor of 20/3 = 6X).  I'm really scratching my head about this amplification.    Previously, I suggested that this "lower" mode corresponded to bearing noise fom the slower-spinning rotor, but I do not believe that any longer.  Perhaps the material in the rotor or base plate is resonating like a speaker cone.  Perhaps something else in the room is resonating sympathetically. 

The amplification is very peculiar to me.   

For the fun of it, you might bombard your device with 172.3 Hz (174 Hz?) from a signal generator.  It "sounds" out there, I know.  I'll reanalyze the audio [again] tomorrow.

Cheers,

You know, Yada, you are working with a wav file which has been slapped around pretty hard to remove most of the hum.  That peak at 172.3 could just be an artifact of the original noise having been combined with a nearly-out-of-phase counter-noise.  The increase in amplitude (while stranger) could be the same thing.  I don't think that I'd make too much of any anomolies you find there, considering what it's been through.

Hello All.

I had the buzz at 60Hz, though with harmonics and parasitic noise artefacts well into the kHz region. I therefore had to use a comb filter with very tight notches to hit the spread-spectrum harmonics whilst preserving flatness as far as possible. I did apply high-pass with an fc of about 120Hz though, simply to clean up the lower frequencies and lift the audible detail.

Notwithstanding resonance that could well be real, it's worth mentioning that audio AGC was in evidence in the video (you can hear the hum change volume - particularly in the earlier part of the video), along with probable resonant mic/environment characteristics  -  both potentially contributory to a non-linear relationship between frequency and amplitude that could be contributing to peaks unexplainable by other means.

For this reason professional acoustic recordings are made with very expensive, spectrally-flat wideband mics that are purpose-designed to minimise resonant characteristics of this nature, though cheap mics (possibly camcorder mounted) don't really cut it at-all.

+20dB gain mid-band is rather a lot though, so very possibly something else going on to explain this.


All the best,

FunkyJive

Hi everybody
Just signed in and tough I'd post some of my toughs about this topic
First let me  to introduce myself.
It' s just in the last few mounts that I got more interested in alternative energy technologies and related projects and devices.
Surfing the net to get some basic knowledge about this subject, offcourse I've got intrigued by the controversial concept of overunity as much as I got interested by several very interesting related devices and relative patents.
Offcourse Al?s first video got me very interested , and in the attempt to make my own mind about what he showed us in that video I'm experimenting whit my two replication rigs , but whit no much success , only AGW locking Whit almost all different combinations between the two rotors ( of different weight ) mounting different sets of rotor's magnets ( still waiting for N35 ?  x  ? ? cylinders mags for rotor ) and many different stators along whit the K&J R834DIA and different dumper positioning.
While I was waiting for the K&J's mags , some days ago I had loads of time to think about the stator's bearings issue.
I focalized on that since Al said that only whit the right combination of  tree out of fiveteen stators he got the rig to perform as shown in his first vid, and that he imagined the cause to possibly hide in the different bearings chosen only for some of the stators Assembly .
Wandering about this subject I tried to visualize what was possibly happening in the bearing while the device was operating in AGW mode ,and exploring the innumerable variables interacting in the apparently achieved anomaly, between them I pictured something that perhaps have no way to be possibly happening in reality, but since I have practically no nowledge in magnetics and consequently in ferromagnetic materials permeability and how fast a magnetic field can permeate a ferromagnetic bearing, I wanted to try to write down this vision of mine in the hope that someone whit good knowledge about magnetism could give me some clue about that.

Between  the other variables that I took in account  , there is one in particular where I guess my imagination went pretty wild .
what I'd like to know is if there is any chance that something like what I've imagined and tried to describe  can really happen in reality .

Please let me know what you think about it .
And good luck everybody whit your projects

Ciao, Andrea!

I saw your post at CLaNZeR's a short while ago, but at that time, I couldn't wrap my brain about your theory.  I will be glad to try again.   

There's an interesting book (PDF) you might read:  The Secret World of Magnets.

Welcome to OU.

RE 172.3 Hz

Thanks for the feedback   

RunningBear, I think you were suggesting [to JFK] that Al lives in Canada, which is 120/60 Hz.

Blue, I get your drift concerning mashed files, so tomorrow I'll analyze the original [dark] YouTube video.  I quickly analyzed it a moment ago, but I'll need a clearer head.  Initially I see the same mode at 172.3 Hz, and it appears to increase 15 dB or so.  Something is there to be certain, but read on ...

FunkyJive, I like your point about AGC!  Anyone who wants to have their audio analyzed should be certain to disable AGC.  Good point. 

Omni, do you copy on the AGC?

Lastly, I'm also a gearhead at heart, and appreciate that "Power = Area Under The Curve."  I'm thinking now that although there was an increase in the amplitude of the frequency at 172.3 Hz, the actual power didn't change, because the side frequencies (e.g. 170 Hz, 176 Hz, etc) collapsed into the fundamental of 172.3 Hz during acceleration (CoE).  The area under the two curves -- @1700 and @4700 -- might be the same.  More tomorrow.

Please keep me in check.  Analyzing the audio is proving to be tricky, and I don't want to stretch too far with my assumptions.

Cheers, 

Yada..
