@Conradelektro.

The larger magnet costs a little more to turn but will pay it's rent in output. There are ways to cheat Lenz Drag. The setup looks lean and mean. Sorry the diametric power coils failed.

There are ways to cheat Lenz Drag.

I also built a new vertical model with a 230 mm long needle as an axis. I did not use any magnets for the bearings just a brass bolt with a little hole as the ground bearing and a hole in a plexiglas plate as a top bearing. See the attached photo. Power draw and spin rate is only a bit worse than with the new horizontal model (about 30mW 1500 rpm to 70 mW 2200 rpm).

When I used a magnet to hold the axis on the top end I run into trouble. The steel needle was magnetised by the big magnet and rattled because the diametric magnetisation of the needle was interfering with the top magnet. Therefore I gave up the magnet bearings for the vertical model. And it is not much worse (concerning friction) and very stable.

I will now make the drive circuit a bit better and then solder two circuits which go on the two models (one for the horizontal and one for the vertical spinner).

The two models have fairly big magnets spinning which should allow to test different generator coils. There is also ample room to place a generator coil or even two.

While I work on my drive circuit, I would be very much interested in hearing suggestions for coils which are supposed to have less Lenz drag than ordinary coils. I will give them a try without prejudice. Because the drive power is feeble, one should see immediately the Lenz drag. I tested briefly with an ordinary coil and the drag was terrible (as one expects).

Of course you should not disclose your Lenz-less coil in case you plan a patent or some other self styling; me or some sneaky reader might steel your idea and become very rich.

@Conradelektro,

Take a diametric magnet and hold the end up to the spinning rotor. Measure the RPM. A speed up will motivate you to build a series bifilar wrapped, spool type output coil, with a core length and diameter the size of two diametric tubes attached end to end. I looped back to source with this kind of magnet core output coil and charged the run battery forcefully. Tape the ends of the coil. They won't attract while spinning, but they will collide when stopped.

@synchro1:

Thank you for the suggestion, I will try. But I do not fully understand your coil proposal. Would it be too much to ask you for a drawing, could be a photo of a hand drawing?

By "diametric tubes" you probably meant "two diametrically magnetised disk magnets", or did you mean "two diametrically magnetised ring magnets".

Sorry to ask such dumb questions.

I held a "diametrically magnetised ring magnet" near the spining magnet (in serveral orientations and distances), it always decreased the spin. Then I attached two such magnets together and the result was the same. But I might have done it the wrong way.

@Conradelektro,

                       I'm talking about diametric tube or ring magnets with a hollow core. Point the end of the magnet or coupled magnets at the center of the rotor magnet at ninety degrees from different distances. Try increasing the strength of the magnets over the rotor strength. Believe me when I tell you a speed up of the rotor will happen if you toy around with it enough. The distance where the speed up takes place is inside the neutral zone, a distance of very small calibration, like a millimeter.

                     Skycollection built a "Lenz free" series bifilar stack of pancake coils with a ferrite toroid in the center. This is basically the same design. The ferrite toroid is wrapped with a coil, and saturates turning it magnetic. The toroid acts as a magnet after that.

                     Achieving a speed up with the diametric tube would only require wrapping a series bifilar coil around it at that point to succeed.
