1.5hp motor conversion

[hiker]

picked up a nice little 115 volt- 1.5hp motor--single phase--two single phases that is..
4 pole........made a new rotor from a piece of pipe..super glued on the mags- double stacked...
then i buried them in epoxy putty..great stuff cures as hard as rock in just a few minutes..
   i going to use the blades and tail from my old duel rotor--just had to make a mount for the alt..
used 2by4s--glued and screwed togeather..
i tested the alt on my pedgen--had no problem lighting up a 450watt--28v landing light..[just short of breath and legs felt like rubber] :}
just need to redo my blades--sand and stain.........heres a few picts...

sorry about the double pict........

I think that is the ticket ,to test small Alternators under peddle power .It translates to less that 6 feet diameter blades with little or no tsr . You should be in the 200 to 600 Rpm range with a solid Air flow . Turbulent winds kind of are equivalent to returning to  slow climb ( under load).
How do the winds run in Alaska ? Do you have long periods of calm ?

i mainly use my windgens  for my motorhome......i drive down the coastal road and park..seems to be a good wind their most of the time.
gets a little scary at times when the wind picks up to 40-60+ mph......i always use a furling tail==my old mill survied 70+mph winds
with a furling tail.. play it safe or dont play at all.................
and yes pedgens seem to work great for a test bed--or just having some fun--i built one for my motorhome as well--saved my butt a few
times when the wind died down and my batts got to low to start the engine--takes about 5 minutes of peddling to crank the old girl over............

Cool

heres a shot of the airgap--super tight..
no real cogging even thou the mags are straight..might be because they dont quite line up on the lams..

What size are the magnets?
Neo?

Hello!

One quick question, and a comment. 

I see that the 'end bells' are open,  Are you going to seal the motor, if so.. how?

Your statement..  "picked up a nice little 115 volt- 1.5hp motor--single phase--two single phases that is.."
Is a bit confusing.   I understand single phase but "two single phases" leaves me at a loss.

450 watts is close to 2/3 horse power,  you're in good shape!

[hiker]

its a split phase motor....two pairs of four coils..
4 wires out..one phase puts out higher volts-start coils?????
havent been on the trails or mountain bike for awhile--when you get in your 50s -you lose it quick-and it takes longer to get it back.......
time to hit the trails!!!!!!!

Nice job hiker.

Please share more details: size of neos used, cut in rpm, plans for it, etc.

Thanks for sharing,

opo

the mags are 18mm by 3mm...i double stack them..about a 1/4 " thick.........
you get 3 for 2.98...  not sure of cut in speed..fairly low rpm..can light up a 50 watt 12v headlite by hand using a pair of vice grips to spin it over..not full bright but close..with a hand drill --it easly lights up the headlite on its slow speed setting..
and you know what it can do on my pedgen...........
fun stuff....its all painted up and ready for a test.........might mount it on the back of my bronco..and drive down to the coast... :]
heres a pict. of the mags and the putty i use to secure the mags....great stuff...
