Induction - which setup ?

[tomster]

Hi Guys,

I've been reading a lot of stuff on this forum and found some interesting things here.

But I have some questions

I'm working on linear generator, but I'm not sure which setup would be the best...

See image below...

let's say that coil is constant, I can change only magnet that moves in coil..

Which one of this setups is the best?...or is there any that's better?

Hi Tomster
I dont see the image. Can you try to reattach it.
Also what do you mean by a "linear generator?
thanks

Hi Bizzy,

You should see image now...

linear gen is the one that moves in line, not circular like most of the generators...

for example, you could attach linear gen to some piston machine and generate electricity that way...

Hi Tomster
An interesting idea! I have worked a great deal with alternators check out my you tube channel

I am not sure which configuration would work best. Is there just one coil around the magnet piston or several. If there are several then you should add more magnets ..if there is just one big coil then use the fewer magnets.
Just curious how are you preventing the magnets from rubbing against the coils?

Well, I'm in theory part of making my generator, so, i didnt have problem with coil and magnet rubbing

I'm trying to find some info on linear generator, and I tought I will ask here...coil size, magnet size, or number can be changed, only thing that can't be changed is movement, which is linear....so, any tip, or direction is welcome...

Hi Tomster

I would suggest using several coils with a ferris metal covering to ensure good magnetic penetration.
If you are using several coils then I would also suggest using several magnets as well. since your coils will probably be round ID I would also suggest round magnets.
Finally to prevent the magnets from rubbing on the coils I would suggest a guide at both ends of the magnetic assembly
Good luck

the more I think about it, the more i like this idea
you could have one electric motor turning a drive shaft, and set your linear coil/magnet arrangements on the shaft the same as a V8 engine is setup.
one motor running multiple generators.
If all the coil/magnet setups were identical, you really wouldn't have to worry much about tuning the output, just have them all rectified and then store the energy in something.
with some good planning, this could be relatively easy to setup and could make some decent power
I am interested in your progress, good luck!

yes...that's something I was thinking too...

I was wondering is there any difference in number and size of coils...

let say I need coil 3 inches long...would there be any difference if I use 1 coil 3 inches long, or 3 coils each 1 inch long.....except for fact that I can connect 3 coils in star and get 3 phase system...

yea, this setup should be more efficient because magnet is fully enclosed in coil and you get advantage of whole magnet, flux, while on circular gen you miss some of the flux...

Hi Tomster
You would get less voltage and current by using a 3 inch coil
My suggestion would be to use 3 or more(six would be better) 1 inch coils about a 1/4 to 1/2 inch thick depending on your magnet strength. The coil width will also be dependant on the width on the magnets you are using they should be the same width.
I would also recommend spacing the coils apart the same width as the coils. This will allow a steady and uniform wave coming from the coils. Also be sure that the number of magnets is great than the number of coils using a ratio of 6:8 (coils:magnets) This will ensure good magnetic coverage on your system.
This is a very fasinating idea
Keep us posted
