Stator and Rotor how to make help needed!

[clflyguy]

DUDE!

  I thought you said you had been reading at Otherpower for two years? The whole concept of these type alternators is having the stator between two
mag rotors to take advantage of the more powerful mag flux available with the NIB mags. Your idea about having an alt at each end has been hashed over
many many times and for efficiencies/costs sake the decision has to go to just one somewhat larger alt. One mag rotor & one set of coils doesn't make
power as efficiently as two mag rotors, one on each side of a set of coils. Plus it's cheaper, because you don't have to make two sets of coils.

-Of course the center pipe turns, why add friction? It reaches from bearing to bearing and provides stabilization to the machine's mass. It does not require
any special effort to turn, as it turns with the mass of the machine itself.

Separated 1 rotor/1 stator sets would actually make for a HIGHER start-up speed because they would have to be spun faster to to make the same voltage as a
2 mag rotor/1 stator alt.

OK lets take this approach then you tell me what is needed and listen so far from what I am gathering I need this.

So materials needed to make this all work are:

- 24 Coated magnets for hughe piggots turbine

- 11 lbs 13gauge magnetic coil
http://www.magnet4less.com/product_info.php?cPath=9_20&products_id=178
- 2 55gal Drums

- 2 Rotors

- Fiberglass and Resin

- Epoxy for magnets

- Shafts
?
- Bearings
?
- Spacer plate for magnets for setting up the space between mags

Does this all seem correct or am I missing something? I guess I need to know the specs of what I all need as far as poles and such so I can get er done and get it started. My main issue will be the shafts and such required there is one local junkyard that I have trouble making it to during the week due to my work hours.

Obviously we will need different bolts and fasteners and brackets I have purchased some angle brackets steels 1/8" 3" x  3"
Lets do it.

Why don't you make me out a complete listing of what I need and I'll go there and get it.

I must warn you ahead of time I do not have a welder personally a friends friend has one wire feed so if I can do this without welding it would be a preference ... Which is why I was suggesting the previous setup. The other way I see it can be done without a welder would be the top rotor connected to the barrels and the bottom rotor and the coils in the center stationary... But this is not what you have planned so I will follow just tell me what is needed.

EDIT we will also need batteries.

Deka MK Gel Sealed what rating and how many?

Charge controller suggestion?


UPDATE: MAGS ON ORDER along with mag spacer plate so I can be sure the spacing is correct looks like its 12"

I did not order rotor cause I need to see what I can dig up possibly... Don't have the faintest clue where to start trailer parks are doubtful but I will look into where to find these things.

What would it be called exactly that I am looking for and need for the shaft (pole) and bearings and where are some obvious places to look for them with a 12" rotor ?

Thanks

Hi Cityboy,

Note to Michelinho- Earlier in this thread you suggested that Infringer mount the mags with all of the same polarity facing one direction-

That was for the real Savonius rotor which uses magnets upright at the end of a flat rotor and coils upright on the stator around the rotor facing those magnets mimicking the window/SSG motor setup.

@ Infringer,

Charge controller suggestion?

You can use regular car batteries because the charge controller is a pulse charging unit and it does enhance the useful life expectancy of the lead acid batteries.

The charge controller depends on your alternator output.

Take care,

i think if you use a regular car battery, you'll be sorry!  you should use a deep cycle battery, like a golf cart battery.  car batteries basically have one job, start the engine.  after that the alt supplies all the power requirements.

i would suggest going with 6 volt golf cart batteries.  this way you are assured of getting a deep cycle battery (and they are easier to connect multiples) .  if you go with a 12volt battery, make sure it is heavy for its size.  most golf cart batteries weight about 60 lbs. (+ or - 5%).  as you may know most car batteries are much lighter because they only need a surge once in awhile, for a short time to start the engine.  lighter = less lead.

also the nice gel and agm batteries are expensive compared to the $60-65 (+ core and tax) at sam's club for golf cart batteries. you will get 3-5 years (on average) good use.  plenty of time to make sure you want to stay with this system.  then if you want a longer lasting (if you don't overcharge them) battery, you can switch.

I have had horrible luck with car batteries...

I dunno dont think I will take that route the deka mk seem fairly reasonable...
