I'm getting a little further. It looks a bit horrible as I am basically using junk reused parts. But you can now get a better idea of my design. Interestingly enough, a spin by hand generates over 7 volts no load. Just seeing what was happening and playing a bit. The magnets are all facing like poles so it is interesting how much voltage is still created from the inductance change of the magnets in front of the core. It will be interesting see the effects on the current draw when I get a circuit hooked up this weekend and get it running. Time to have a little fun and learn some stuff! To my knowledge, nobody has ever tried this design and using both sides of the electropermanent magnet against like pole magnets. Ignore the terrible craftsmanship, lol...

@floor,
I do need to do a bit of house keeping in here. But I guess I'm not sure how to do it. I don't have the permissions to delete anything, so I thought maybe I would just copy into you dust bin but I can't seem to post there. So I guess I really don't know how to do it after all. Can you give some tips please. Thank you.

Yes.

While doing some house keeping of my own, I inadvertently locked the dust bin.  It's not
supposed to be locked / sorry.

This process is new and not at all well tested.

1. Copy  items to dust bin. 

Attachments are a pain, they do not copy / must be moved to your own
computer and then reattached to a post in the dust bin.

Good ordering in regard to which is attached to what does not matter there.

The whole affair is a courtesy any way / for the record kind of thing
and its is all your own call. 

2. Post in your topic.  Floor please delete messages x, y. z...
                         example this very message is
https://overunity.com/19040/permanent-magnet-assisted-motor-coil-designs/msg564032/#msg564032
              and
Floor please delete messaage
https://overunity.com/19040/permanent-magnet-assisted-motor-coil-designs/msg564032/#msg564032

 Thanks for your patience.
                  floor

 P.S.
    There is another method for you to move attachments.  It's simpler
I'm not very practiced at it yet and don't feel confident in explaining it.


1. Go to O.U.. com  / login
2. Start a reply in the "Floors dust bin" paste there ...
3. Open a second browser and goto O.U..com  (you are already loged in)
4 Navigate to the Jpg. or png. or so on... that you want to copy,
                             Right click on it and select copy.
5.Switch to the other browser that is looking in the "Floors dust bin"
6. Below attach: click browse
7. Right click then select paste.
8. Change the name of the file you just pasted, else it has only a file type or extension.
                                      Right click on it then select rename.
9. left click on the renamed file to highlight it
10. Left click on "open"

             Again, the whole affair of moving a post, is a courtesy any way / for the record
             kind of thing and its is all your own call.

 you suppose that shorting the winding around a permanent magnet will break the symmetry of the approach and removal forces of another magnet ?  After all, closing the coil leads by contacts does not require any energy consumption. Isn't it ? Perhaps there is something in this. :)

Hi captainpecan, 

Using junk reused parts is perfect for experimenting and overall cost may remain low. And no problem with your craftmanship at all.   

Would like to understand how you meant the process I put in bold above?  i.e.  if the magnetic poles of the electropermanent magnet (epm) appear at its top and bottom ends when you switch the coil on, say N at the top and S at the bottom, then one rotor magnet would repel one pole of the epm (say the top one) while the other rotor magnet would attract the other (i.e. the bottom) pole of the epm simultaneously.  Is this how you meant?   

EDIT:  Thinking this over again, you mentioned the magnets are all facing like poles that are embedded in the two rotors) and I connected this to the electropermanent magnet which has unlike poles at its ends.
 BUT then, to change the attract force to be a repel force, you can flip one of the embedded magnets to have its like pole face the also like pole of the electropermanent magnet, so there will be no problem in this respect. 
 Is this ok?

Thanks, 
Gyula

I actively use it. Fortunately, there is a large number of old household appliances remaining from repairs for spare parts.

Hello here's a video on the recepicating Flynn motor .I can't understand him but the concept it pretty clear its a scrap project .so low cost .and I think I might leave out the middle bar and put the coils on the top and bottom bars that would give more space for magnets and you could run some bolts top to bottom to hold things together .I like his use of plywood he just lays it out on it and goes like that .and by being able to easily disasimble things you can a just things like more magnets or windings .the generator must be moved by the out put of the flynn so there's a balance going on between the coils power .and I've been told the coils out put needs to mach one of the magnet stacks if I heard that right .so some tunning in going to be done .so easy break down in in order .for more windings or less .this post just covers the Flynn the next the generator with magnecti neutralization .

Another video real good .in here he says he's getting 1,000 out for 400 in .my thinking is the rotory Flynn is to much for me now but if I can retain the 1 to 4  ratio then use that on this magnetic neutralized generator I'm looking at 100 in to 1,000 out at best .but I'll take anything at this point that will charge my batteries while I sleep . both are over unity but together wow !.

There's more if you need it .there's another video on a reciprocating Flynn .that shows the construction layout if you need it .

Would like to understand how you meant the process I put in bold above?  i.e.  if the magnetic poles of the electropermanent magnet (epm) appear at its top and bottom ends when you switch the coil on, say N at the top and S at the bottom, then one rotor magnet would repel one pole of the epm (say the top one) while the other rotor magnet would attract the other (i.e. the bottom) pole of the epm simultaneously.  Is this how you meant? 


I actually didn't write that very well for understanding. What I meant is that the top of the electropermanent magnet is N, and the top rotor is all N facing down towards the electropermananet magnet. The bottom side is the same just all S poles. I have enclosed the permanent magnet inside the coil with 3 mm of steel so it is just enough to cancel that pole (by giving the flux an easy path to stay inside the core) and allow a like pole magnet in the rotor to attract to the core still. So even though the rotor magnet is a like pole, it is still attracted to the electropermanent magnet core on the way in much like if there were no permanent magnet in it at all. Then when it is pulsed just like a normal electromagnet, it reacts the same except now the field of the hidden permanent magnet is released also as a bonus pushing force. An attempt at much greater force per pulse. And I am using both ends of the electropermanent magnet so the rotors not only get a pull inward from both sides, they get the push of both sides on the way away plus the extra push from the permanent magnet for the same initial energy in one pulse. That's the theory in design anyway. I've been working so much I still haven't finished making it run yet. Hopefully soon and I'll post video.

That's what I'm hoping for and it looks to be true so far.

I may be wrong on Flynn as a motor .it says it puts out double machnical energy not 4 ,.but it puts out 4 times as much flux .so it might be better use it as a  magnet assisted transformer where the Flynn is the primary .we will see .any motor putting out twice mechanical is a really good motor .but 4 utilization is better .

@Jimbo,


Yeah, there are some good nuggets of info in those videos. Makes sense. Different than what I'm doing, yet, similar underlying concepts. It's that reverse way of thinking that is so intriguing to me.
