Hilden-Brand Magnet Motor

Hi,

the outputcore is just iron, but there is another image,
I hope this is a bit clearer.

Thanks,

Adalbert.

Thank you guys.
Yes, Nali, I've tried coil without magnet (but solid core instead) and did not notice any difference. But it's hard to say exactly without proper measurements (just used rpm compare).
Looking at Jack's pictures I believe his rotor works against solid block of stator (like on the picture below). Yes it runs. But I found, that in this setup ('magnet gate', like SMOT but with magnet) it runs much faster.

Now I'm trying to switch polarity  to reverse field right after 'dead spot' (in the middle of the 'stator'),  to get another pulse at the same spot (seems it's became just a pulse motor, not a Valve, but for me it seems more efficient). I already tried this with magnet (Valve) and completely destroyed pretty powerful magnet (field of steel bushing worked against field of magnet and demagnetised it).

Still interested in Liberty's thought about solid state arrangement of this model (I think if Jack patented his idea there's nothing wrong if we will discuss some other possibilities).

Thank you, hartiberlin ,
But as you can see it's a little different setup, I think.
Will keep in picture if find some improvements.
(still can't open even my own postings, work just by 'reply' mode; something wrong with my comp I guess...not sure if pictures come through, sorry if so).

Hi Light,

I would try to set the output coils between two of Jack's valves.  You could make a ring out of them.  The core between valves should be laminated silicon steel or maybe magnetite.  The core should be twice as long as the magnetic valve shield to allow the magnetic flux to fall back to the valve instead of the next magnet.  You may need to have a paper gap between the laminate core and the magnetic valve to assist in valve operation (this may help it to continue to switch with a small air gap?)  I would pulse the coils all at the same time.  The output coils would have to be in phase if placed in series so the output does not cancel out.  I included two visual pictures except the core in the pictures is not long enough (should be twice or more as long as the magnetic valve length, I would guess to allow the flux to switch back to the valve).
This is all just a guess, as I have not tried any of Jack's valves or solid state generator. 
I think you could use any number of valves and collection coils, (assuming that this works).  It would still be interesting to see how Jack set his solid state generator up...

Hope this helps.

Hi,
The latest design I did last night that was based on 50mm wide laminated steel sheet was simulated in Femm 4.
I am not going to attribute the design of the valve to Jack as his idea is taken from the Nasa boots, who probably took it from someone else so for now I will refer to is as a magnetic valve.

I kept increasing the current until the flux was hardly changing.
+50mA to turn the switch on and -10 mA to turn it fully off.
I could just let it drop to 0mA but the was still a bit of flux left(0.1T) in the core.

I plan to buy about 10-20 of 25mm Sq by 12.5mm height n38 magnets.
Also for measurement I will get a AD22151 linear hall sensor to place tight inside the core to monitor the flux density.

It is important that people remember that to switch the flux, only a very small current is needed even with this setup which is 0.5m wide and 0.13m hieght and 0.05m depth, weighting over 20Kg.
The power is 0.2Watts(500 turns 0.2mm copper wire for each magnetic valve) so if you are pumping 30 watts and over then you have missed the point altogether.

Measurement of coil current and flux density is important to getting this setup to work.
Thats not to say that as soon as you load up the output coil the switch will stop switching, this is where testing will show up this issue.

I can get 8 output coils on the two main yokes of the core, but these were not shown in the simulation I did.

One additional note and thought on the pictures of the Solid State Alternators:  The valve should be tested separate from the circuit first to make sure that it is operating correctly.  The paper insulator may not be needed, because the Lentz law that would be in effect, would feed back a magnetic field that is the same as the poles of the magnetic valve under load, but slightly delayed.  This action (Lentz law) may actually help to shut off the magnetic flow from the magnetic valves with a short repel field, due to pulling power out of the device.  It may have a limit as to how much power you can develop or more likely, how fast you can pulse the coils for maximum effectiveness.  From what Jack tells us, a slower pulse works better.  So 60hz just might be a nice number.  If you have enough coils to develop 120 volts, you would not need an inverter for household current.

Why not use variable Crystal Oscillators to do the switching? Just a thought.

Like this one rated ajustable 1 Hz  to  20 MHz  temp. stable

Hi,

I cannot help but mention to you that the crystal oscillators included in your link are not adjustable continuously in the given frequency range (i.e. between 1Hz to 20 MHz),  rather it means that they manufacture such crystal oscillators to any ONE particular (user defined) frequency within the given range and it can be only adjusted against aging.

A typically active crystal can be tuned by changing the reactances included in the oscillator circuit and the rate of pull generally is 1-2 kHz for each value of MHz, depending on the activity of the crystal: for instance you can adjust the output frequency of a 10 MHz crystal oscillator about 10 x 1 kHz=10 kHz to 10 x 2 kHz=20 kHz max while the stability does not suffer. For a 5 MHz crystal this is 5-10 kHz only.

If you look for continuously tunable frequency 'generator' you may consider the good old NE555 timer IC for purposes needed in this thread, there are many circuits with it on well searchable websites.
