Statorless Generator, no field magnets

[Cadman]

I had an interesting idea IMO, and one I intend to test. It just sort of popped into my head when I wasn't even thinking about such things.

You have seen the videos showing how the magnetic field in a round bar magnet does not rotate when the bar is spun on its axis, haven't you?

I wonder if a copper wire were to be wound in a N-S fashion progressing around a bar magnet and always staying in one pole, say the N pole of the bar, if it would generate a current as the bar magnet was spun. The coil would look sort of like the stator winding in an automotive alternator, but wound right onto the bar. I can see the coil wires being cut by the stationary magnetic field lines as the bar turns.

Wouldn't that be a hoot? A generator that only has an armature?

Would it be affected by lens, and be harder to turn as the rate of spin increased?

How much current could it produce, if any?

Ha ha, if that part works then a whole bunch of those coils on the perimeter of a rotor face would generate power as the rotor turned too.

This can't work, it's too simple.

electric experiments by robert33  yt  shows rotor / winding   powered by ac on each side of the bearings or rotor itself
with dc supply a magnet is placed near the rotor   like one used in vacuum machine

Hey Cad

Ive done some experiments on this. I believe its the same concept.

It is said that the Faraday dynamo, a U magnet and a spinning copper disk, produces current in the disk. But then when substituting the U magnet for a disk magnet, and, rotating the disks, magnet disk and copper disk together, the copper disk still produces current.

But what I have found is, if using separate magnets in place of the solid disk/ring magnet, the flux moves with each magnet, where the solid ring, the flux does not rotate with the ring magnet.

Below is a pic of my version of what should have made current in the coil by just moving the structure as a whole through the air or space. But it doesnt.  I tried a few different versions.

Cadman that certainly is an interesting idea, gotta be worth a try. Certainly can't hurt to give it a whirl. I gotta ask the question, did you think of how you would take the current from such a rotating coil, it would require slip rings.

Although I think the Faraday "dual disc opposing rotation" generator designed by Tesla is the pinnacle of Faraday disc generators. With the currents taken from both shafts, no need to have a contact to much faster velocity peripheral edge. However I don't think he used one to power any of his experiments, which makes me wonder, why not, the only reason I can think of is that the voltage is so low the transformation up to the High tensions we require would incur substantial losses.

As a low voltage high current supply for a DC electro-magnet it could be useful.

Interesting idea, i will try this if i a have time. If this produce current it will really confirms that the magnetic field is stationary.
