Fan to n-coils to fan

[AquariuZ]

Here is something that I would like to know...

Imagine a fan electric motor attached to a rotating rod of undetermined length and material. At certain distances small magnet assemblies are placed on the rod, and a matching copper coil on the outside -but not part of- the rod. Each of these coils are attached to a capacitator or battery, daisy chained to each other.

When you add sufficient coils and maybe add shielding between the coils so they do not interfere with each other individually. The only weight added to the rod (which may be any low weight material) are the magnets.

Would it theoretically be possible to close the loop?

Silly maybe, but, well, it is half-baked...

Hi AZ
Is'nt it just a motor running gen.running a motor,with Mr Lenz doing his bit with the coils and mags?

Maybe... I just wondered if you can reach a threshold where you can have a capacitator power the motor with the power generated from a number of independent coils.

I would gather it is important to individually isolate the coils because if not you would have an overall zero gain.

Don't know and wonder if anyone ever tried this.

Hi AZ
Not sure I understand "I would gather it is important to individually isolate the coils because if not you would have an overall zero gain"
could you explain?

I believe what he's saying is not that everything is as straight forward as one single theory. I do believe overunity is possible with a conventional generator and electric motor.

What turns a motor is F= BIL what makes a generator generate is U=BLv. What you want is high current so low resistance and slow rotation of the motor. While on the generator part you want low current so high resistance and high rotation. The motor will thus generate very little back EMF while the generator will generate very little back torque. The output on the generator will be very high voltage at low current. Assuming you can step this down to low voltage and high currents you are home free to close the loop.

This can be shown easily mathematically. But who's going to build the whole thing  .
