Working Magnetic Motor on you tube??

[FunkyJive]

If acceleration or momentarily sustained speed is in evidence with Bruce's motor then this could simply be the result of harmonic resonance as the kinetic energy in the main rotor reduces. However, this would not suggest a rise in latent energy from the initial spin.

By way of a simple example, using a hi-fi speaker emitting a falling bass tone in a room with multiple resonant/reflective paths, one could simultaneously turn down the volume and frequency -  though a relative increase in perceived audio volume (at frequencies of room resonance) would not suggest an increase in output power. At such points it would merely be a reduction in loss that resonance brings about.

However, from the various posts and results that I've seen, I believe that resonance is almost certainly a critical factor to get this motor to work at-all, where weights, flux density, diameters (etc etc) would collectively prove critical in achieving positive results. This is where I believe that a motor-driven system to monitor energy absorption could prove invaluable in establishing where those points of resonance may exist and would offer the means for optimisation. Here a simple (unrelated) example would be to manually tune to a radio station (to hererodyne and therefore tune at the right frequency), though a broadcast signal is first needed to reveal when optimal tuning has been achieved. A driven rotor would effectively provide that "broadcast signal".

Now looking at new Specs

144mm Diameter
18mm Thick HDPE
Spacing from edge of Rotor to inner magnet line 13mm.
1/4 " Slots 12mm deep.



Have cleared 2mm off a piece of 20mm HDPE so it will be 18mm thick.


Weight without magnets or axle is 246g



Weight with Rotor magnets added it is 271g


Instead of marking the magnets with a Pen I have used insulation tape wrapped around that also makes the magnets fit tight into the rotor.

Ran out of time for this weekend as have to set off travelling early evening, but will try mount it maybe.

Cheers

I agree, these are the lines along which we should try to seek the solution. This has to be explained away better, though: "then [the ostensible acceleration] could simply be the result of harmonic resonance as the kinetic energy in the main rotor reduces." Acceleration needs energy input, not reduction. Unless, you can show a mechanism whereby the initially imparted energy is somehow discharged differently than the way it goes down in an usual wind down and somehow turns into input rather than loss.

It's a long shot but there could be an elastic function between the rotor and the stators whereby the stators store some of the energy imparted into the rotor and release it back again. looooooooong shot .. given that there is no quantitative measurements of acceleration.
If we could see that the stators slowed down in relation to the speed gain of the rotor .. then maybe .. but that doesnt seem apparent even from casual observations made of the videos.

Hmmmm...

Bruce,

Nice Vid!

I have sound too.. though i find it hard to perceive the acceleration. Is it at all possible that you can do this by fixing the stators in place with blue tac or something as I can't help but believe you are adding energy into the system (not accusing you of deliberate fakery).

Cheers,

@Dean
How could he add energy? He did not do any additional movements other than the start up.
hmmm.... maybe he was wiggling his fore fingerÃ, 

Dean.... why don't U construct one of these little beast? Then U can answer all your own q"s
U must be thinking of the Steorn rep video where the guy was oscillating a magnet to induce rotation ?

Specs are too loose and no convincing reps so far, otherwise I would certainly try.

@dean_mcgowan
So, since you plan no attempt at replication, are we to assume that you are simply positioning yourself as a stumbling block to those who are?

If so, what is your ultimate gain if you are successful?
