Hello, I name the idea Sotogen
The idea is to turn the core it self, with stable coil around it as close as it can. By doing that you remove the second gap of the clasic rotating iron and so we get only one gap as a regular generator has, so the losses are minimal.
The drag of the core at full load will be close to 0. The core here is invisible for the coil, even its turning.
take a strong magnet and stick it to a small motor , with one pole point out and one in and as it turns, insert it in the copper pipe.. what you see? no drug? ;)
the swithing of poles is easy to understand from the diagram, number of poles and magnets has to do with speed, and less or more clogging. But clogging can easyly bypassed by combinining many sotogens in a circular mode with gearing and different timing so the clogging will be history.
The core material must be laminations or ferrite or any modern high switching frequency core material.
The construction looks easy but needs work :)
i ll be around for any question :)
It is a variation on a stepper motor.
Hello l0stf0x
Could you please make a drawing of the experiment cited below so there is no missunderstanding?

Was this the experiment that led you to the Sotogen drawing - could you please explain in detail what experiment led you to the Sotogen?
THX in advance!

the setup is shown at the diagram.. test it
the magnetic mass/flow does not change for the copper even the core is turning. because magnet's or core's flux is always even at every side and the coil just see a stable core. But using this we can get the switching easy... just do the test
Thanks for sharing your very interesting Sotogen design idea l0stf0x

You are welcome Luc :)
sorry for the poor drawings, I don't have it with 3d software. :)
The difficulty is at the construction of the core. Actually the center shaft at the drawing show as 1 peace. Its wrong, it should not pass all the way from inside of the core. And better to be magnetically insulated material like aluminum bars on bearings with special endings to screw them on the rotating core...
The laminations can be pre-cutted to sizes so when you join them altogether, at the center of it will be circular and perfectly symmetrical as it can be. The 4 core branches are angled on purpose, to be away from copper, and for better magnetic flux distribution.
Thanks for this extra very important information.
I'm thinking of a simple material to use for proof of concept.

Maybe ferrite will be better if you have them.
solid soft steel is not suitable for ac swithing, but for just to proof the concept its ok I guess :)
I will use laminations because I have them already here (from large transformers), and I also have some huge neodymium magnets that I want to use, so I need a big core.
I forgot to say that the angled branches must be as short as possible..
