A progress report, for anyone interested.

The first coil is a 5 pole made out of poster board and wound with 400 ft of #24 magnet wire, 9.2 ohm. The winding is N-S along the axis, all in the same direction from one pole to the next, like this VVVVV. Every other layer criss-crosses the previous one so 2 layers look like XXXXX.

Surprisingly the generator concept seems to be valid, but I made a mistake in the build. The steel shaft did not magnetize well and to make a long story short, it was weak and the bloch wall ended up being slightly off center of the coil windings instead of at one end. I think this caused the opposite ends of the coil to mostly cancel each other out, but it did produce 1.4 vac @ 1300 rpm which is encouraging.

My thoughts at this point are to replace the shaft with a non-magnetic one, hollowed out on one end to insert half of a N42 neo into the coil winding. That should fix the bloch wall problem and tells us if this idea is worth pursuing any further. If it is, I may try winding a coil like a dc motor, one complete pole at a time.

That's all for now.

Cheers

I see another great mistake here. You might thinking that the coil will generate a higher voltage than the tube. But if you think carefully you will realized that the tube and the coil will generate the same voltage. I know it was confusing but at first im also think the same. Also you should not criss-crosses the coil as the generated voltage will cancel in each other.

Tube? I'm confused. What tube are you referring to? All I have is a magnetic shaft with a coil on it.
And point noted about the coil winding. Thanks.

Im comparing the copper tube and your coil will produce the same voltage like the copper dics and spiral pancake coil will also produce the same voltage. You only increases the resistance of the circuit by using a coil so its much better to use a copper disc or a tube than a coil.

Is this just theory of yours or are you building a device to test? That would be excellent.

My thinking may be all wrong but if the design succeeds in generating significant electricity then there are further possibilities to explore with coils. The first test was supposed to be a single wave winding, which I screwed up by using 5 poles instead of 6. The next will be a proper wave winding and if that works then there is the possibility of having 3 coils to generate 3 phase, and that can be rectified to dc with a minimum ripple if desired.

Underlying this whole idea is a generator that would not require more power to drive as the load increases from 0, only the power needed to overcome the mechanical losses from rotating the armature and the friction of the brushes.

It was based on from what i read on other experimenter and from my own opinion.

Like you im also making a high voltage lenzless generator but first im trying to figure out how can i remove the back torque so im experimenting on faraday disc generator hoping to break the secret. From what i understand you like to a make coil on wave a pattern but how it can help to remove the back torque?
