Permanent magnet assisted motor coil designs

[captainpecan]

I have been seeing bits and pieces of work done by others that coincides with work I am doing as well. I also realized Floor was working on similar concepts 9 years or more ago. I just wanted a good thread to share info about these ideas and to post my own work as well as I work through some concepts to learn more.


First off, I had always been experimenting with sticking a magnet on the back of my pulse motor coils and seeing how it effects things. But I never got to deep down the whole idea of digging way deeper into what is actually going on there that appears to boost the output with no more energy, or sometimes maybe even less. I will try and reference others works as I find them here. Please feel free to share anything you know of as well. I believe if there isn't any OU available from these various setups, there is at the very least extreme possibilities of increased efficiency.


First off, it was work done by Robert Murray I saw on his youtube channel that inspired my current design I am working on. Here is the video I am referring to.

I probably am not aware of many others who have worked on projects in this area but I know some was posted in another thread I will reference below.
Some very good info including patent info was posted by gyulasun on jimbo's thread here...

Here is a post from gyulasun of much interest...

Hi Jimbo,

The concept of embedding a permanent magnet into a ferromagnetic enclosure and use a coil to control the setup was also proposed by Jack Hildenbrand, see his drawings in his thread here: 
https://overunity.com/833/hilden-brand-magnet-motor/msg22925/#msg22925 

He built several motors with his concept, you can see some pictures on motors he uploaded in his thread but later he deleted them all (mainly due to the patenting process) and someone from the members here saved some of them in this site:
http://purco.qc.ca/ftp/Inventors/Jack-W-Hildenbrand/ 
In the folder you can see a video on a test demonstrating the Hildenbrand valve principle, done by another kind member here back then. 

Jack patented the concept as "System and method for utilizing magnetic energy", US7453341, the pdf file is also included in the folder.   He claimed a COP of around 2 (to 2.5) for his motors based on the concept https://overunity.com/833/hilden-brand-magnet-motor/msg23790/#msg23790 
(COP = Coefficient of Performance).  Unfortunately Jack deceased in an illness soon after he got the patent and, as I know, no successful replications have been done ever since to get COP > 1 with the concept. 

There was another member here, DMMPOWER, who showed a drawing on the concept as a "super" electromagnet, see here:

And see Floor's post with a link included in it:
https://overunity.com/13354/perm-magnet-only-core-with-iron-shell-motor-coil/msg563135/#msg563135  and see the start of the thread here:
https://overunity.com/13354/perm-magnet-only-core-with-iron-shell-motor-coil/msg354318/#msg354318     

Please do not misunderstand my mentioning the above examples, your efforts and enthusiasm are appreciated and please continue tinkering with this concept.

Please feel free to post any other info anyone may have relating to this concept. I do not wish to take any credit away from anyone and their work. I simply want a thread I and anyone else interested in working with this concept can compare notes and share work.

Here is the coil design I am currently working on. A good part of it is very similar to a drawing Floor posted some time ago. I am aware a magnetic field is not a perfect oval as depicted here. It's just what I was able to draw easily to show the concept of how the field will work. It's close enough to get the idea across I believe.

How it should interact with the rotor. The first one is with the rotor having soft iron on it that is attracted to the electromagnet while turned on and drifts past it when turned off.


The second one uses a rotor with all apposing magnets. Because the field is mostly enclosed in the core of the coil due to the added iron on top and bottom of permanent magnet, the rotor magnet will now be attracted to core instead of slightly repelled by the opposing magnet in the core. After rotor magnet attracts to the coil, just after center, the coil will be turned on. This will create a much stronger repelling force shoving the magnet away.

Here is the coil I have made so far. As done by Robert Murray in a video I posted previously, I have used a stack of washers glued together that my 12mm by 12mm neodymium magnet fits in the center of. I also have some 1/2 inch 1 mm thick metal discs. I glued 2 of them in the center of a washer to create the sealed core on top and bottom of magnet. This allows a permanent magnet to interest woth the the core and be attacked to it even though the 2 magnets oppose each other because the flux is held inside the core.

And here I have my first coil made. For this one, I am trying high number of turns with thin wire to see how strong of a magnetic field I can get with smaller current draw.


This is 2200 turns of 30 AWG wire. Coil isn't looking perfect and is a bit ugly with super glue drying funny and other things. But it is a solid coil to use.
