You sure can try it, but i highly doubt eddy currents will have any significant effect on the field of the big magnets.

Also if you use ferromagnetic material with holes you got problem of magnets wanting to stick to non hole parts.

One approach might be to copy Muller and use odd number of holes arranged in such way that rotor does not get stuck ever.

That's a good idea too.

This is an example of the large interrupter area I was talking about earlier, this is for Giron which is nothing more than layers of woven wire sections at angles to each other, held together with a plastic material.

Passing this kind of material through a magnetic field would generate induction as well as eddy current.
If the interrupter material is non magnetic the only force affecting the rotor would be electrically induced magnetism.

Problem with that is big magnets will care about those eddy currents as much as elephant cares about an ant in it's way.

One thing that should work is what i already mentioned..

To have an iron plate with magnets in opposition to stationary magnets on each side of the plate, thickness of the plate and size of opposing magnets being balanced so that they neither attract nor repel big magnets, yet, since there is iron in the middle, big magnets are 100% screened.

I've tried that with opposing magnets. It works, but like you say magnetic lock is a problem. The Muller method would definitely be beneficial with it.

Your probably right about the eddy currents, the more I think about it, it would have to be the induction currents that affect it the most. Giron is a super expensive, slightly magnetic material that will block the field between two magnets. Problem is it takes several layers of it to do the job. That is with the material stationary to the magnetic field though, so no induction current. I'm trying to come up with something similar that will do the job with this application without spending a fortune.

Anyway, we’re just discussing possible ways to duplicate the DS generator. By the way, that device we’ve all seen is just a proof of principle prototype. I don’t believe the pictured device has the output of 50kW per coil pair. I think that one would be much larger.

Good discussion. :)

If done right there should be no locking at all.

I would love to see your build of it some day.

If I ever get the chance to try my ideas I will definitely post it on the forums. Maybe we can exchange some other ideas.

Have a good day.

Yesterday i been reading a bit old thread from 2007 about Window motor, here is Stephan's drawing of supposedly Neman or Newman like circuit for capturing the backEMF.

It's just full wave bridge rectifier and then a cap in parallel with the stator coil.

Current from the battery is clearly allowed to go into FWBR to charge the cap.

Altho this is very simple circuit exactly what happens is unclear and it depends on that switch in relation to inducing magnet(s).

Maybe Newman took advantage of high inductance coil and delayed Lenz and only closed the circuit at times when Lenz was not breaking the rotor.

This should solve the problem from the previous page, how to capture the first backEMF from a coil so that no current is ever used from the battery.

Two time synched transistors, one creating a pulse from the battery to the coil and an instant later another transistor turns on so backEMF is allowed to charge the battery. Then they turn off in same order, FWBR can be added to capture collapsing backEMF too.

Well the simplest way rather than cannibalizing the washing machine to get a water pump could be to use a synchronous cooling fan mechanism and cut a section out of the rotating section and place a NeD magnet in it's place. simple and easy to get hold of.

Smith has quite obviously not released anything of value.

Dare to open your eyes: https://youtu.be/yLjt3y1_ceY?t=4011   https://youtu.be/oyionE-sCis?t=3205

"On DC you can actually put a load--you can dike this white wire and put in a load. We've had a situation where we've had one hundred and eighty volt DC motor, three horsepower, with Twenty six milliamps exciting--spinning. No load, but it did spin at full 3450 rpm". https://youtu.be/oyionE-sCis?t=3396

Displacement current. He probably thought it was obvious to most.

We all know what displacement current is, regular current "through" a cap
is displacement current, suppose in Don's demonstration other side of the cap
was really connected only to ground. He used a Tesla coil to excite one side of
the cap and Tesla coil is capacitively coupled to ground, even without the cap,
especially so with one which is grounded thus closing the circuit. I am not saying
it is not possible to extract energy this way, all i am saying is that circuit was closed.
