Graham Gunderson?s dragless generator patent, Lenz law violation !

Hi Marcel,
Just completed two simulations:
1. showing an air filled hole
2. showing partial steel filled hole.

Just guessing here, but I would think that it would be important in this design to not magnetically saturate the core of the ring by using too many or too strong of a type of magnet.  Perhaps weaker ceramic magnets would be useful towards  leaving some room for a rotating magnetic field to possibly have an effect.  Limited amount of output power might be an issue too, due to core saturation/magnetic strength issues within the toroid core?  As I recall, wasn't it reported that this device worked with gain at low power levels?

The coils and ring were very nicely made.  Well done. 
I would try using about a couple of magnets at a time and just see if you can get an output out of part of the ring.  Then when that works, "magnetically" space far enough away from that and add another pair of magnets and replicate the magnetic circuit that worked all around the ring.

You guys seem to forget that the "open ends" of the magnets will "dive directly down" into the core. Which you do not want. So you need to close loop them back to a opposit polarity. See the crappy drawings I made. Also I think that there is only one imput coil needed not one for every magnet. The output coil though needs to be many more turns.
Maybe It's of use to some.

Hi Nali,
Yes, I agree with that, the magnetic circuit needs to be closed to allow more flux to flow into the core.
Although if you look at my simulations, even a weak magnet may suffice without closing the circuit.

Another suggestion is to put the holes through where the centre of the input coils are.  This is where the flux density is at its greatest and lowest.
Or have two holes, one either side of the magnet and use two output windings.

Hi Marcel,
Check the output windings have not shorted out on the sharp corners of the core holes.
You may need to countersink the holes slightly and paint some varnish on the metal around the hole to protect the copper wire enamel from being damaged.

Hi there Rob, Nice femm simulations you have. Altough I must point out that simulations are so rough that they only act as generals idea's of what the flux will do in reality. This has been said before. But it's true. Other thing is, when you are drilling the holes too near the imput coil's field, and so plan to put the output coils there you are in a sence going to power the output coils dicectly with the imput coils and have not much more than a regular transformer. And so the imput draw will increase accordingly with the output load. Coupling between input and output must be minimal. Imput coil should only act as a mean to push or pull the field of the magnets to a certain direction. And so the magnets will do the 'cutting of the coils'
