@ Tak,

I know, also the same technology is used in small buzzers where the loudest possible noise with the smallest possible power consumption is more important than the quality of the sound.

Someone should have been asking questions about the device's potential for overunity long before now.

OK, so now we build a bigger magnet magnified "speaker", disconnect the speaker from the connecting rod, then attach what?

This is a new area for me. What is the most efficient known method for converting a pulsed force into electricity? Attach a magnet and shuttle it back and forth in a coil?

Also, is it essential to have a horseshoe magnet, or could it be done away with and just use magnets in place of the pole shoes?

With these question answered I'd know if my thoughts on a few ways to maximize the force and do away with the spring steel might work.

Hans,

Greetings from the mild west of Canada! Does your 'more elegant' system still involve any moving/pivoting/swinging/rotating/pushing parts? No need to divulge yet, just curious to know if I should think of a better design than my current one, which has movement reduced to just linear motion of a transfer rod through a guide bearing.

I'm still not sure this can be done without a horseshoe style magnet. Can't know for sure until tried I guess.

I have been thinking I had seen something like this before. Finally found it.

This guy was doing something like this with magnets and pivots.  You might want to look at his stuff too.

hansvonlieven, I am assuming you will be using a pulsed power source for the input and I am wondering if you have considered using the back EMF from the relay to enhance the output?

G'day Nightlife and all,

You are correct in assuming that my device requires a pulsed power source. I have not thought about using back EMF. At this stage I want to get the mechanical problems out of the road and get a prototype running. There are considerable problems yet to be addressed in relation to the timing mechanism. Once these are overcome we will need to have a look if we can utilise back EMF.

It is early days yet.

Thanks for your contributions and suggestions. They are welcome.

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.

G?day all,

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

 

(http://keelytech.com/freischwinger/freischwingerprinciple.jpg)

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:

 

(http://keelytech.com/freischwinger/developideas.jpg)

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.
