Overunity Device using Magnets in the 1920's ?

[neptune]

I do not wish to discourage anyone from doing research. Personally, i feel that although this balanced armature device is very efficient at converting milliwatts of power into sound, it is probably not overunity. It just appears so, because of the very low efficiency of most loudspeakers in use today. This is not a problem, because audio amps are very cheap to make.The real difficulty , as always is measurement. How can you accurately measure sound output in watts?

This is possibly right. We don't know for certain though, do we? I feel it is worth inquiring into.

First we have to get away from sound to make real measurements, on that I agree. I am addressing this.

Hi Hans and all,

Somehow I still feel first a setup with a conventional electromagnet as the input power receiver is to be built and do our best making the output generating coils to produce at least the 60-70% of the total input, right? So far this is an unusual but valid AC/AC converter if you like with an expectable efficiency.
And when we have such so called converter working fine, we could improve the input power receiver electromagnet with the addition of permanent magnets and see the hopefully useful effect of them in the reduced input power needed for the same output power as before without the magnets. 
Say we have to input 15W to the normal electromagnet to receive 10W at the output, this is about 66.6% efficiency and surely could be achieved.  Better designed converters boost an efficiency number of well over 90% in a certain (narrow) output power range.
After the addition of the improved electromagnet with the permanent magnets at the input, let's say we find the input power needed now is only 8W to get the same 10W output power. This would be about 125% efficiency (or a COP of 1.25). 
Hans, I like your proposed principle and I also can understand you wish to start with the improved electromagnet. I hope you will succeed.  I just think to follow a safer way and work out.

G?day all,

Before we go into the design concept for a motor, let?s have a look at the principle involved here.





Fig. 1   shows the device at rest. There is no power supplied to the coil. The soft iron reed sits at the midpoint between the poles, held in place by a spring. Since un-magnetised iron gets attracted by either pole there is equal pull from both sides, therefore the device is in a state of equilibrium.

Fig 2   shows the coil being energised by a forward current. The soft iron reed has now become an electromagnet. The illustration shows the forward current forming a south pole facing the horseshoe magnet. The reed is now attracted by N and repelled by S giving it sharp unidirectional movement.

Fig 3   shows the current being reversed in polarity resulting in movement in the opposite direction.

What is remarkable here is that it needs very little power for these reactions to occur. The slightest magnetic bias in relation to the magnetic field of the horseshoe magnet triggers a reaction. The real work is done by the permanent magnet.

I see it like putting up a sail in a breeze. The more sail you put up the more power is delivered to your boat because you catch more of the wind.

Similarly here, the stronger the bias the more of the energy latent in the permanent magnet is caught.

Now this is where I get into trouble with conventional physics. Conventional physics sees the permanent magnet more like an anchor against which the electromagnet pushes or pulls itself toward dependent on polarity.

My leaning is more in line with Leedskalnin and Keely who see magnetism as two opposing streams of very real particles which cannot be created but only channelled by such things a permanent magnets and electromagnets and a whole host of other things where the effects are not as readily observable.

I see the permanent magnet like some sort of a canal where the particle flows are determined by the physical constraints of the channels, whereas I see the electromagnet as a sort of two way valve controlled by an electric current.

Of course what I am saying here is pure heresy as far as conventional physics is concerned, but I have been called a heretic before, so it does not distress me unduly.

But back to our subject. The two main questions that need to be answered are: Can a motor be built using the Freischwinger system? and Does such a motor exhibit overunity?

The answer to the first question is: Yes a motor along those principles can be built with comparative ease.

As to the overunity question: Perhaps it can, experiment will tell.

So how would one go about designing such a motor?

Playing around with the fundamental principle I came up with the following approaches:





Fig. 4   is just a extension of the original device. I have put two discrete magnets here, though a horseshoe magnet can be put in its place. At the moment I don?t know if discrete magnets work in the same fashion. Something to find out.

I extended the reed upwards from the pivot to get more horizontal movement in order to drive a simple Faraday generator. The springs are still required to keep the device centred when quiescent. I did not like this as it costs energy. I decided to do away with it.

Fig. 5   shows a pendulum arrangement. This was a bad idea! I decided to try a pendulum to get rid of the spring. The problem with this is the natural frequency of the pendulum.

The natural frequency of a pendulum is solely dependent on the distance between the fulcrum and the centre of gravity. In most places on earth (as gravity varies with latitude) that means that a one peter pendulum completes one cycle every two seconds, a 25 cm pendulum has a natural frequency of 1 cps and so forth. Since 1 cps was far too low for any practical application and 25 cm was about as small as you can get that meant that whatever pulses I fed into the device would have to overcome the natural frequency and force the vibrations. That would have cost a lot more than a spring in terms of energy, so it was back to the drawing board. Besides, I was unhappy with the reciprocal action of the device. Converting reciprocal movement into something usable is always inefficient and cumbersome. That is when I decided to try a wheel.

Fig. 6   shows the next arrangement. It became immediately clear that here was a far more elegant solution. I could try for rotation.

The result was the following design.

Sorry fellows, on this one I am reserving my copyright, because I think here is a very real chance for something worthwhile, perhaps not overunity, but at least a fairly substantial motor that can run on very little energy. You can build the thing for yourself and play with it as much as you like, power your house or car with it if you can, I wish you well. Only where commercial exploitation is concerned I reserve my rights.

So here it is:





Now this looks suspiciously like a common garden electromotor. So why should this thing be any better?

It requires only small pulses of energy to run.

I will go into the timing and nature of these pulses in my next article. In the meantime enjoy the animation.

Hans,

Bravo! You promised elegant, and elegant it is!

I also like that the timing doesn't have to be exactly in the gap, as any pulse within the gap or the following pole shoe zone should work. The number of stators is probably only limited by required magnetic shielding. Very nice!

Options for horseshoe mags would be NIB arc segments, steel horseshoe with mag pole shoes, or maybe quite long bar mags.

I don't have the necessary parts on hand to try this out, but surely someone in our diverse group does.
