Self running coil?

[Allen Burgess]

4 x inductance.

look at this bucking wound inductor and the Flynn force schematic. Doubling the magnets between two stators yields nearly 4 X the magnet force: Connecting the counter wound coils in series generates 4 X the inductance! Tying the two pins accross the top keeps the current going in the same direction, and the fields act as the two magnets we see in Flynn's second sketch:

Bifilar magnet strength.

There's been a lot of contoversy over the merits of the bifilar versus the single wire coil of equal resistance. The series connected bifilar will generate more magnetic force past an input value. We can add power to a Tesla coil and the magnet field will grow stronger in proportion to the input. The single wire coil will no longer generate a magnetic field past a point of input, but only generate heat. The Tesla bifilar coil will not produce any greater field strength per unit of input over the single wrap, but you can power it up to a higher magnetic force!

Hi Allen

I am hoping you do a demo? Please continue and be redundant repeating
yourself til the rest of us catch up with what you are saying.

let me read this again. You are talking a delicate balancing act.

Thank you Allen

After energizing the electro-magnet
coil, both the field from the permanent magnet cylinder and the
electro-magnet coil would combine to raise the core's saturation
level.

This saturation level should equal half the inductance drop for a
Tesla bifilar or bucking pair coil .............. when the coil inductance
and magnet field strength are balanced. This means the coil has the
storage capacity to generate a magnetic field equal to the ones induced
by the permanent magnet and electro-magnet coil combined.

Self running motor coil.

@BroMikey,

Thanks!

Gotoluc demonstrated the self running coil. We can improve his design with the addition of a "Magnetic Amplifier" (MagAmp) to generate constant power from a self running motor coil while changing speed.

We need to balance the dwell in the power coil as we speed the rotor up because the lower the inductance the higher the frequency. So we would add power to the magnetic coil to increase saturation and lower inductance then add power to the propulsion pulse to speed the rotor up to sustain the generation of power from the motor coil: Otherwise, we'd be busy with cocktail coasters and matchbook covers adjusting the magnet gap manually. It would take four potentiometers to run this self powering motor: Pulse width, frequency, power and inductance, plus an LC meter.

Ferrite core.

I just ordered this 1/2" diameter 4" long 2000u ferrite core. Cost $32. in shipping to Costa Rica costing $24 apiece:

A permeability of 2000 is ideal for the frequencies involved in the 5-15 Khz range. I plan to wrap this core with a D.C. mag amp winding then cover it with a Tesla bifilar and check the alterations in bifilar coil inductance with an LC meter, while energizing the core wraped electro-magnet.

Relay coil.

Attaching a 12 volt relay coil to the back of the ferrite core, in series with a pot and battery would make a powerful (quick and dirty) saturating "Mag Amp" switch. Placiing a disk magnet behind the relay coil so the coil's between the magnet and the ferrite core would maximize efficiency. The relay coil could then act as a fine tuner. This eliminates the need for an additional core winding. The tuner needs to raise the level of core saturation as the rotor accelerates along with the addition of power to the pulse coil. The assisting magnet lowers input to the relay coil and reduces heating. You'd need to get the motor running to really gauge the value of this control.

The exposed coil in the relay below needs to be broken out of the container. Very powerful precision electro-magnet with a high grade core:

Electro magnet

I bought this electro magnet online at Amazon for $12.89 for my "Mag Amp". This is the best money can buy!

Inductance.

Iin Gotoluc's "Self running coil #2 video", Luc lowers the inductance of his toroid coil from a 1053 Millihenries to; 44.6 mH, by saturating it with 4, 1/2" neo disc magnets. A reduction of over a thousand milllihenries! Way more the 50% reduction I mentioned. Placing 3 or 4 neo disks on the end of the electro-magnet core and then placing the electro-magnet next to the coil would make an efficient Hildebrandt valve. Luc saturates his toroid coil very powerfully. You can see the thin slivers of paper Luc uses to space the magnets in video #2. A potentiometer on an electro-magnet can simplify that job alot. Technically it would be called a: Hidebrandt valve Mag Amp.

Magnet core

Igor demonstrates how a magnet core supplies more torque then just an un-magnetized magnetic ferrite core:

"A coil wound around a magnet (instead of around a metal core) creates more torque on motors of Adams's principle. Pulse motor with amplified "core". There's a Art Porter GAP effect. Adam's type is (Mono-polar) magnet direction on the rotor.

https://www.youtube.com/watch?v=rIi6P30hrKA

It's fair to infer that rotor torque increases with core saturation. Luc has his toroid core magnetized to over 95% of it's capacity! This much saturation would be enough to add a GAP effect increasing torque in a motor rotor. The backspike from this self powering bifilar could energize a high voltage seconday power coil as well, to double efficiency!

[Allen Burgess]

Adams masking.

Magnetizing the core can help attract a magnet rotor of opposite polarity. The power pulse acts as a masking field. Luc's twin coil toroid would probably power a rotor in Adams attraction. The masking pulse would have to synchronize with the mono polar motor virtual R.P.M.

The opposite pole of a rotor magnet would be attracted the magnetized toroid core pole untill the power pulse neutralized it.

Gotoluc originally built his toroid coil to power an Orbo motor with that kind of masking power. How simple would it be to include a "Mag Amp" and power pot on his self running coil, and run the Orbo motor in self powering mode?

A "Switched Reluctance" motor with a mono pole rotor and speed of 300 R.P.M.

Here's Luc's GOBO magnet motor from six years ago: How come he never hooked it up to his self running coil?

Personal message to Gotoluc.

Dear Luc,

After reviewing twenty one of your videos on the GOBO and "Self running coil", I have to wonder why you never bothered to hook the GOBO rotor up to the "Self running coil" to create the "Self running motor"?

Sincerely,

Allen

Tuning magnetic field.

Watch JLN finely tune his magnetic core field strength for maximum efficiency (Fishing by hand):

Compare JLN's technique with the Electro-magnet below, Hildebrandt valved, in series with a potentiometer!

High perm core.

Gotoluc's advising a very high perm core material for the toroid that's rated in the Mhz frequency. There's no advantage to inductance raising the BH curve above the intended frequency. Higher perm allows for higher switching but the magnetic field is less powerful.

The 100 Khz rated toroid core material I selected measures 1000 uH of inductance with merely ten turns of 28 gauge wire! Gotoluc has 500 turns on each half diameter coil to reach 1045 uH of connected inductance with his choice of Mhz core material.
