  Me thinks this might be an answer to the amtec-motor generator thing I tried last year.This is a 50vdc motor its geared about 3 to 1....Spining it by hand I get about 14vdc into a batt bank.Cant wait for the wind,so I can see what it will do...

I too have done the same arangement only into a 24V system, the six blades are the answer, insuficient torque with only 3 blades.

From what I can see yours should work a treat, lotz of angle on the blades, how did the static ballance go?.

There apears to be no furling on the tail as was mine, the blades seem to be adequatly self limiting on their own.

does it make much noise?

Nice, Let us know what she does with a good wind.

  Now this is a sad story,the faint of heart cover one eye while reading this....

     And it came to pass that the chain was not staying on.While trying to make some adjustments I droped the amtec...It hit the cement and now the rotor wont turn.I got upon it with all four feet, no turn....I took it apart and what do I see ? The ceramic magnets had broken in several pieces...I am trying to replace the old mags with some new ones...Moral of the story dont drop the amtec-motors.....

Ouch, sorry to hear, mate.

Good luck getting her back together again.

If the performance is anything like the looks, you'll be matching the Hoover dam for output!!

Something like this for that little treadmill motor I'm working on in my diary...going to use

that belt drive ...about 5:1 ratio automatic variable tension and clutch...won't have any cogging problems!(...If I ever get that far!)

:

    Made from 5 gal buckets cause I can get some

of these easier than plastic pipe...I may make my

next one with longer arms narrower blades and

maybe 8 blades.

    What size chain are you using? or just bicycle chain?

I also dropped a pm motor a couple of days ago

...cement floor but it hit my leg first, I had what they call mixed emotions everything was all

right after some cussin' and limping around.

  Hey norm what did you say got mixed up? Yes its just bicycle chain #41 i think....Nothern tools sells 60 tooth sprockets cheap but the chain is # 35 maybe i should have went that route... cause getting the sprocket to run concentric is a buger with hand tools  ...... I think the belt drives take a lot more power to run that chains, the belt drives i have tried required 750 hp just to turn them...

       Does some one know if in amtec type motor if  the mags are NSNSNS around the case like an alternator ? or does the same pole go up like SSSSSS ?           MelTx

Mel;

The Ametek mags [like any other] alternate poles and there are 2 of them.

Cheers.

Thumbs Up!!

Great looking job.Hope you get your wind.Any idea what rpm will be on the prop at 15 mph.wind?

[Norm]

  Get an old 10 speed just like Hiker did...

put the rear wheel cluster sprockets on the

Amtek shaft and the crankshaft sprockets on the

blade shaft...line up the chain of your choice...

  I'm not going to argue with you about belt

drives, just simply to say the belt drives you tried were the wrong kind of belts.....



  This could be made to have an automatic tension, the faster your turbine turns... the more

load... the more tension (just enough to keep it

from slipping) when it's going slow ....less load

less tension...this arrangement would work really

beautiful on an F&P ...you wouldn't have to worry

about the cogging issue...but no one seems to think so...guess the only way is to make one to

show how feasible it really is....

                  Have Fun....MelTx

                 Just tryin' to help

                and give you some ideas

                to work on.

Au contraire..... I do think so.

Just got to find a solid rubber tire to mount on my trailer hub. However I was thinking 2 rubber tires, a big one and a little one. By making the pivot point for the F&P axle off-center to the prop, the tires will suck in when spinning and increase the tension.

here it is--just a test setup..

moved on to the 12" dual rotor alt--time to fire up the motorhome and drive down to the coast and give that a test..this whole thing started out just to have somthing to charge my batt in the motorhome when i run the furnace--even thou i have a gas gen for it..dont really care for the noise..and with the price of gas!!!!!!!!!!
