Working Magnetic Motor on you tube??

[ken_nyus]

Some of this data capturing has already been done by Al, on the working device.

Coil readings of the stator, coil readings of the rotor, and coil readings of the space/interaction between the two.

See the images on Clanzer's site for details.

Some data relating to relative rotational speeds of rotors and stators before during and after accelleration and deceleration would be a huge help. Preferably not based on audio samples.

A long-shot but for fear of being dubbed "The crazy old preservist of out-dated analogue"  , how about using stereo audio recording channels to record the changing fields generated by both stator and rotor magnets in combination. The only requirement would be a few tens (?) of turns of an air-cored coil, with two such coils coupled to L & R channels respectively.

This would be really easy to analyse, the loading on EM fields would be doubtless insignificant for a few mV of required signal, and simple to reproduce graphically? All that would be needed is a stereo mic/line i/p that has (say) a -20dB bandwidth down to a few tens of Hz, as I'm guessing that the amplitude would be an irrelevance as it's the phase relationship between the rotor and stator that requires analysis here. However, you could also see elastic wobbles (should they exist) as HF sinusoids co-existent with the fundamental, and perhaps provide the means available to most to capture and compare results like-for-like.

Just a thought

Works great and generates nice sawtooth waves - which are easy to measure the time between because they come to a point at the top.

RANT ALERT !  Please bypass this reply if you don't like my ideas.  If, however, you can relate to the below idea, please send me a back channel message.

Jai Guru Deva, Om.     Today, NASA beamed the Beatles song "Across the Universe" into space.  Song @YouTube.

Many of you know that I have an interest in sacred systems.  For example, I think there is something to be said for a pentagonal rotor and a hexagonal stator, because Nature favors these geometries.  In Nature, many plants that bear fruit have 5 petals.  Cut into an apple -- horizontally -- and note how the seeds are arranged.  Neodymium has a hexagonal crystal structure.  There are many examples.  I hope the WhipMag bears fruit.   

But enough about sacred geometry, let's consider sacred sound and Al's rotor.   

In my previous posts I mentioned that Al's rotor appears to exhibit a characteristic frequency near 160 Hz.  This number sounded familiar, so I did some research.  In additional to 96 Hz and 225 Hz, 160 Hz is a secondary tone that arises out of and complements the fundamental "C" tone.  The primary Solfeggio frequency is 174 Hz (see PES Wiki frequency section).  Today NASA sent another message into space, that contains the phrase "Jai Guru Deva, Om."  OM or AUM is the basis of all sounds in the universe.  I thought it would be interesting to compare a spectral analysis of a monk chanting "OM" to Al's rotor spinning at 425 Hz.  Enjoy.

Keep replies in the back channel, please.  Thanks.

Cheers,

Hmmm...  I feel a tune coming on

@Yadaraf,

That 63Hz was present in the resonance section of my wave and was absent in the section at ~400rpm (outside of the resonance region). Is Bruce's 63Hz also within the resonance area or outside of it? Also, in my resonance part there was a 2kHz peak which is absent in Bruce's wave, correct (@alsetalokin's has 1.6kHz at ~400rpm while mine doesn't show any in the kHz range at ~400rpm)?

@Omni

RE 63 Hz:  I believe it appears in all of your audio tracks thus far.  I've reanalyzed the first soundtrack you provided (see below).  Also, Al probably had a mode at 63 Hz, but the loud background hum obscurred it (in my sample but not FunkyJive's).

Here's what I think: 

...We should expect two characteristic frequencies (modes): one corresponding to the rotor bearings and the second corresponding to the stator bearings.

For the same RPM, two different bearing sets will produce different frequencies due to the size of the ball or cylinder in the bearing.  A ball/cylinder that has a smaller circumference will make more revolutions as the entire bearing rotates, and, thus, produce a higher frequency.  Follow?

Al's system had modes at 160 Hz and 900 Hz.  I'm guessing the lower mode corresponds to larger bearings (rotor?) and the higher mode corresponds to smaller bearings (stator?)

You had two modes as well, possibly:  one at 300 Hz and another at 1000 Hz (look closely at previous figures).  Again rotor vs stator

My hypothesis answers the following question. 

... Q:  Why did Bruce have only one mode at 300 Hz?


Lastly, it appears that you and Bruce are using the same rotor bearing.  Are you? 

It looks like Al's rotor bearing is much different.   


I'm going to bed.  Night. 

Cheers,

I?m using the bearings R188 recommended for the rotor. I think they will be worth playing with only after the rotor weight is fixed (which won?t happen tomorrow, as I expected; last I heard it?s gonna be on Thursday). Then, the question of rotor and stator kgauss profile is to be understood and so on.

Also, remember, Bruce and I were working on something different from what @alsetalokin did. We had N42?s on top of the stators and my stators were additionally somewhat fastened. So, when I get my rotor back I?ll have to send you soundtracks from the real replica for comparison with the soundtrack of the original.
