Fan to n-coils to fan

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.

>>You have the start of a good idea.  There are others that think along your lines as well:

Their assertions were similar to yours.  Several coils can be used in one setup, so you might be onto something.

I myself have thought of a setup involving using the pulsating electromagnetic field of a fan motor to amplify the Back EMF of it through a Caduceus coil and then harvest it.

Hi Broli
Thanks, it has been asked before on this forum,but I've not seen an answer,that is Di's it take the same energy to produce say 10 watts,
whether it's 1vx10amps or 10 amps x1v,it seems to me better to have the highest poss.volts but the out come is still 10 watts.

I'm no electrical engineer but I don't know how easy it would be to for instance step down 100 volts to 1 volt with very minor energy losses.

Hi Broli
Thanks for your reply,but forget the trany,maybe the 100v or even 1000v is just what is wanted.

I meant isolating each individual coil so that their respective fields do not influence each other. It is hard to explain in my laymans terms...

Thanks for the link, yes it looks like what Bendini is doing only I had something simpler in mind. Indeed just coils charging batteries feeding the batteries that runs the fan motor....

The other question would be if spinning magnets on a rotor would cause drag on the coils? If so that is an extra parameter to be taken into account when calculating the maximum number of coils whiich could be added (or the load that the fan motor can handle, i.e. the maximum weight/ lenght of the rod that is being turned by the fan motor).

Glad to see that it is not so weird an idea...

I have a fan motor, now with magnets coming I might try something. (Have just two batteries at the moment though)

Thanks guys
