I was again surprised to find nothing on this page about DAN QUALE's lenzless generator. Found here...

The idea is very simple and effective. You have a rotor with washers. in his case the washers blocks the magnetic field to the cols. The coils in turn see the change in flux and induce a current to counter this change. Now at the moment he hasn't shown really high speeds of his generator, Only hand spun. I think his current setup will give rise to Eddy currents in the washers he uses. These can be eliminated by engineering though. By using thin laminated pieces or some other method. Also the difference in neodymium magnets and ferromagnets hasn't been shown.

Now imagine this generator hooked to Lindermann's attraction motor. You have on one hand a highly efficient motor that gives you almost 90% of its energy back and which provides a non conventional electrical power-to-torque ratio and on the other hand hooked to this motor you have a generator that has no drag on it.

Regardless this makes for a simple replication project.

Hi broli - thanks for the links.

Interesting idea/build, but I don't see it being lenzless.  Maybe low-lenz drag due to the large airgap.  And he comments on the drag created between the washers and the magnets, which would be IMO much larger than the lenz drag.

So I see it as reduced lenz due to an inefficient air gap and also the washer setup helping but trading traditional lenz drag for an even larger drag between the washers/magnets.
Net result: worse efficiency than a standard design.

capthook sorry but I disagree. I also thought about eddy currents heavily dragging the rotor but when he let it run down the rotor should have stopped way before the video ended. EVEN if we agree on this fact there's a SIMPLE engineering solution to avoid eddy currents. And that is using laminated washers in such a way that the eddy currents will have a hard time flowing. Here's a diagram that shows mainly the orientation of the laminates. The rest of the diagram shows a hypothetical improvement on his current design. I don't know how well it does really though. But theoretical there should be no back drag what so ever. But in practice there's no such thing as a uniform magnetic field so there will always be small losses.

When the "breaker" rotor is not near the magnetic fields are mainly crossing the air gap. As the breaker nears the magnet field prefer the breaker and the breaker also gets attracted by a magnetic force. At TDC the washer conducts all magnetic field while the coil is doing its thing inducing currents and what not. As the breaker leaves There's again an attraction force of the magnet but that's not a problem since it got attracted by an equal big force at the first stage. Since this a symmetrical process the net force is 0. Resulting in the in free energy from the coil at no cost from the rotor.

I tend to chuckle whenever I see a ‘Lenz Free’ claim. Generally, if it is Lenz free it simply cannot work or do work.
I believe the only motors that can work without Lenz use the Lorenz force.
If a coil works then Lenz is part of the action.

So, even the generator I proposed several pages back is not completely free of Lenz.
In order for Lenz to be a factor there must be a variation of flux density. Without this variation there are no eddy currents or induction. If this varying flux only varies in the proximity of the coils and not the source of the force (i.e. the magnet or exciter coil) then there are no losses at the joining of this force and the rest of the mechanism. In other words… keep Lenz at the coils only and not between the coils and the source of that force. This equals no drag on the driving mechanism.

While Dan Quale’s efforts may lead to something new I’m quite sure it will not be OU. Any time you have ANY cogging there is drag. Even when the in and out force equals zero. His large gaps and incomplete magnetic circuits should always result in very low output voltage and power.

The only chance to produce such a device is to make rotary motion result in linear change with no variation in the flux density, as seen by the source. Unfortunately, such a machine is difficult to build even though it is very simple.

I appreciate the work being done by others but I found a very long time ago that complexity leads to failure, in machine and circuit design.

I'm not going to start a discussion about semantics here. The operation is obvious and simple. So I don't know why you're saying it's complex. Sure there are some parameters to play with but that's the whole point of research. When I said the speed of the rotor is independent of the generated power that's of course not 100% true. You can't spin it at 1.000.000 RPM and expect to have a linear behavior in output vs rotor speed. There are technical limitations like saturation and what not. But like I said that's the fun of research. So belittling a new idea like that puts you on the same page as ignorant skeptics in my book. Your "idea" is not better imo. You "idea" is pure words without a single proof of concept. As a matter of fact your idea is highly complex. It has a million parameters  :P.
