Title: important questions, about motor/generator magnets.
Post by: nitinnun on February 03, 2009, 05:27:29 PM
i have big plans.
i also have great difficulty.

because i'm having severe trouble,
with mustering mental focus,
for "certain ranges" of "mental processes".

i just need a few short, sweet answers.
if someone answered this, it might help me A LOT.


(i have found a simple way,
to bypass the need for transistors,
in a motor.)

(if someone answers my questions, i might reveal this.)


1:
imagine a "normal motor/generator".
the kind you buy from the store.

it turns kinetic spin, into electricity.

2:
i spin the motors axle
(with what, i won't reveal at this time).

3:
a wire coil passes by the north pole of one magnet,
and passes by the south pole of another magnet.

4:
electricity is generated, in the wire coil.
to power a light bulb. or something simple.




my questions are these:

1:
if the magnets are neodymium,
than will i get more voltage/amperage,
than if i used weak magnets ?

2:
does magnet strength, even make a difference ?

3:
number of coil turns, increases voltage/amperage, by how much ?

4:
how might the number of magnets,
or the number of coils,
be adjusted,
to increase voltage/amperage ?

5:
how might the position of magnets,
or the position of coils,
be adjusted,
to increase voltage/amperage ?

Think of the generator as a water wheel. Put small cups (week magnets) on it and it requires less energy to spin the axle and move water (electricity) than say big cups of water (neo magnets). So yes and no, neo's will give you higher amperage in a smaller unit than ceramics but no free lunch. This will also created more resistance ( needing more axle power). as for poles , that depends on the rpm and how clean you want your electricity. Most gens are 4 to six poles, but if your rpms are 20,000 u could go with 2 poles. Thicker wire more amps, to thick makes its less efficient but safe from overloading and burning out. You need to consult a motor builder. It will start with rpm and diameter. check this out   http://www.youtube.com/watch?v=AWpB3peU3Uk


whach all the vids and learn a litttle sumn, hope this helps a little

1: Yes because you increase magnetic field.

2: Not really if you have to deal with lenz's law. Without lenz then YES, huge difference see above answer.

3: It's linearly. So 2 loops is twice the EMF 100 loops is 100x the EMF you had with only one loop.

4: Again if you're dealing with lenz's law you're going to get nowhere with more magnets and coils. But if you kill it then every addition will be linearly as above.

5: This is where your creativity begins. Hint: look at my latest lenzless motor thread.

why do neodymium magnets,

require more energy to turn the wheel,

than weak magnets ?

does each wire coil HAVE to have an iron core ?

what might the voltage/amperage output be, with just a wire coil ?


what if there is no iron core,
but the wire is thick,
and the coil has hundreds/thousands of turns ?

your answers helped me somewhat.
so i will tell you my "simple trick".


you have 2 electrodes.
both are flat plates.
both are the size of your thumbnail.

one electrode is positively charged.
the other electrode is uncharged.


the positive charge can jump between the positive terminal,
and the uncharged terminal,
without touching.

they only have to be close enough.



if the uncharged terminal is attached to a spinning wheel,
and the uncharged terminal is attached to an unmoving wall,

then the charge will induct, when the wheel moves them close together.
then disconnect, when the wheel moves them appart.


1 rotation of the wheel,
equals 1 connection,
and one disconnection !

the faster the wheel spins, the more times they connect and disconnect, per second.


if the wheel is disk shaped, you might fit many electrodes onto its surface.....


if you were "creative" with the wiring job on the wheel,
you could make it so that some electrodes "connect",
in certain patterns.


one of these patterns, might work like a transistor !

another pattern, might even work like an IC circuit......


you will have made a large IC circuit, which can be designed to conduct FAR MORE voltage and amperag,e than a normal IC circuit.

because it is a mechanical "lego" IC circuit.
and it is as tough as its materials !

@nintinnum

Ref your Questions - my bests..

1: YES  mor Watts


2: JES , for mechanical Input and electrical output

3: onli the relation inut to output power, will inrcrease the efficience

4:  any 

5: adjust to maxiumum flux, for maxiumum result
