Mechanical Resonance (Projects)

[Magluvin]

This test was carried out to see if it is actually the oscillating magnet that is creating most of the current flow in the secondary,or the field distorting the field of the primary.

I added a diode in series with the FG output and primary coil to chop the bottom half of the AC.
The schematic below--not sure of dot convention,or how the common ground between my FG and scope will affect the seen results--but they are clear.

The first scope shot is with out the magnetic oscillator in play,and the second scope shot is with the magnetic oscillator in play.
As we can see,it is the oscillating magnet that is inducing the bulk of the EMF across the secondary/resistor combo.

My next goal is to get the 1:1 transformer wound,and also to set up the laser timing to see where the magnet is in relation to the primaries current flow.

Excellent test.

Does loading the sec affect the primary with the magnet in play? Just wondering as it may play out differently if the primary and sec were not wound over each other, as in putting the sec on the other side of the magnet to isolate its affect on the pri.  If winding the sec over the pri and loading the sec further reduces the primary input, then it is good as is.

Thanks for all your time with this Brad.

Below is a video demo I did 7 years ago demonstrating that a magnet vibrating or oscillating at the same frequency as the coil will cause a reduction in power consumption. In my case 3 times less power at the maximum frequency of 160Hz.
There is a limit to how far you can increase the frequency, which I think is caused by the friction or losses the magnet experiences while in oscillation.

Quite sure this is part of what is going on in Brad's tests as far as input power reduction.

Hey Luc

Nice vid. It seems to be conclusive that if we power a coil with ac, that introducing a magnetic motoring portion that the coil drives, that the input seems to be reduced, whether it is a rotor, a vibrating magnet or as you have shown. 

So as we go along this is something we should expect and strive to improve on as part of increasing efficiency.

Thanks for bringing it here.

Hi, can you further decrease the input by making a pulse instead of a sine wave?

That is my very next experiment.

Maybe the travel will not be enough?
Maybe a magnet on a wine glass lol
Sorry,couldnt resist that one.
Brad

Brad, but that is maybe the classe difference, this is a nice satire!

Tired, mine Grammar is ............

Maybe you're I stick and driven like you do, is perfect!

And 6 pcs more left beside the I stick, and also 6 pcs more Right beside your first I stick.

North-Poles on all 13 sticks UP, related to diameter, bit to close together, so magnets FIELDS bounce, figure from the eagle view is a non-triggered flat wave sinus moving, serpent?

The middle one I stick, is driven like done and the rest follows.

Bit like out of mine example: With the protective people surroundings from the BAD actor Royal-BBC, when they follow resonance, than let them also help to drive 13 coils above the N or South pole.
