Perm. magnet only core with iron shell, motor coil
« on: March 05, 2013, 06:11:50 PM »
The drawing and descriptions I am posting are not a very clear explanation at this time.  So I will make a clearer explanation here:

The design is of motion producing device, linear or rotary.

A permanent magnet is embedded within in an electromagnet. 
This electromagnet  / permanent magnet combination
is embedded within a magnetizable shell ( probably made of soft iron lamination ).
There is no core inside of the coil, other than the permanent magnet.
The permanent magnet's strength and it's distance from the shell that encloses both it and the coil
allows little or no linkage of the permanent magnet's, magnetic field with the magnetizable shell.

I have named the combination of these three elements an electro permanent magnet (E P M).

When the coil of the E P M is energized so that the coils magnetic field is in alignment with the permanent magnet field,
the electromagnet will have a percentage of the permanent magnet's magnetic field added to it.

When the coil is not energized the E P M will not behave as a magnet, and there will be no magnetic attraction, to
other E P Ms or other elements of an electric motor design, except when the E P M  or  E P Ms are  energized.

Interesting  :)
Have you done any more than the idea and drawings, anything physical built and measured?
If yes, can you share any numbers? Thanks for contributing!

I have not built any prototypes yet.  I am still looking at variations of design.  I will be posting
these variations before I move on to building a prototype.  I'm considering a variation of one
of the linear models for a first test.  I intend all of this for the public domain.  As soon as it hits
this forum please consider it anyone's to use, share, publish or sell,  as long as so doin,
does not prevent anyone else from doing so as well.  With this exception: keep in mind that
ideas / designs that I post could have been previously patented by someone other than
myself.


Thanks for the inquiries.

This last jpeg is the architecture for the first prototype I'm building. A Linear motion version.

A permanent magnet ONLY "Square Drive Motor" design, UNTESTED. and an easy to build quasi test model.

The  square drive motor motor, of course does not work.  Gravitational pull is constant while the the magnetic fields decreases by
the square of the distance from the magnet's poles. The magnets will only displace each other by 10% to 15c% at  right angles.

Here is a photo and drawing of a test device, designed to crudely measure the square drive interactions. I may have misstated the magnet displacement created in the test device.  I think the attracting force magnets were displaced at around 30% by the repelling magnets.

Here is a photo(poor quality) and drawing of a test device.  Further experimentation is needed.

A permanent magnet is embedded within in an electromagnet. 

My first reaction is that, unless you are very careful, the electromagnet may tend to de-magnetise the permanent magnet.

Hello Floor,

you may study Al Porter´s website if you like: http://www.gap-power.com

Here are his intro-videos. Choose the full length video if possible

Hi Floor,
  I assume that the 'EPM's are the part of the setup which you think may provide OU? Are you working on the basis that they will provide more magnetic force than a similar coil with a steel core for the same input power? If so - then you could just test one of those...

However, I think it's likely it'd give you much less magnetic force than a standard coil - because the PM core will not contribute as much field as a steel core would. Also, if the steel casing isn't magnetised by the PM when the coil is off - then surely that means it's won't be contributing anything when the coil is on either. So the overall effect would be as if the coil had no core at all. Also - as the metal casing goes all the way round - it shorts out the magnetic circuit - so there would be very little field outside the casing.

Imagine two solenoid coils, one stationary and the other current reversing on a treadle. The treadle has a charging magnet piston attached to one end to supply output through a pickup coil. The unit should run close to unity with an equal charge to both coils. 


Replacing the stationary coil with a PM of equal strength should deliver the same output. Doubling the strength of the stationary magnet stator should yield a COP of >1 right?

Hi Synchro. Not sure what you mean about a 'treadle', google images thinks thats part of a sewing machine...?
Or a 'charging magnet'...? Maybe a diagram?

However, in any standard type of generator, it's Faraday's / Lenz's law that limits the system to COP<1, not the strength of the magnets. To make a generator OU, I think you have to change the geometry so the back-emf has somewehere else to go - other than just straight back at the rotor. But you also have to make sure it has something to react against - else there will be no real power in the output - like the 'toroidal generator'.

Maybe it would be possible to design a generator where the coils' back-emf react against each other - rather than the rotor... ;)

@Paul-R

Yes I think you are correct, at least for most types of magnets. Neo mags would hold up better, probably ?
