I'm thinkin about bolting a pulley on this thing and having the variable speed seems like it would be perfect.

What are ya'll using?
-
that motor is 2 amps, what was it used for?
i am no expert, but that motor having such low amps tells me it cant be used to turn anything like an alternator, i could be wrong? the rpm's is good.
my motor is 1/3 horse 5 to 8 amps. what is 1/5 horse compared to 1/3 horse. my motor is just about as small as you can use. just be carefull and dont burn a good motor up!
-
i dont think that motor will work, you will smoke it very fast! it looks to be a bench grinder, if this is true than it has no torq, i am only trying to save you your motor here!
-
lol ya its a small grinder.
Amps needed to be higher like 10amps the only part i like is its variable speed.
What motor do you use hydro?
-
i use a 1/3 HP 120 volts ac 50 to 8 amp motor. sometimes you can find these motors on squirl cage fans in old shops, most places that sell pulleys sell them. here where i live a good motor is 100 bucks a pop.
1/3 HP is very weak, but it gets the job done. i prefere atleast a 1 horse or even bigger, the rpms of my motor is 3500 rpms, but if your motor is 1800 rpm's you might can use a big pulley down to a small pulley to gain 3k at the alternator.

I just got this 1 1/2 hp 3,400rpm unit for $50
I cant wait to try it out!
-
oh man you done good! i really like that motor!

yeessssss ;D :D
Its got 2 different sized pulleys. One PULLEY IS 3" OTHER PULLEY MEASURES 2 1/2" DIAMETER.

hrmmm, i would probably use the smaller one, is it much bigger than your alternator pulley?
thats about the rpm's my motor is, accept yours want slow down under load like mine does, :( im jellouse!
-
Look on e-bay there are lots of different ones to choose from. This is the only one I saw with 2 pulleys on each side though.
I got this motor shipped to my door $57 :P
I haven't gotten an alternator yet. What would you say is the best one to go with?
-
nice set-up. Whats that clamp holding the alt. initially used for?

The AC Delco alternators from GM cars from the '70's to mid-80's are the easiest to work with as you can easily take them apart to make your wiring changes. In addition, even with the core charge they're cheap. I recently bought one for a '78 Chevette (future H20 vehichle) and it was under $40 from Advance Auto. This is what I intend to use.
-
I found a westinghouse 8.7A 1725 rpm motor , and a AC Delco alternator. the alternator needs rebuilt, but I was going to open it up anyway ;D. I may need some help on that wiring job .

you need a bigger pulley on that driver motor.

I got this alternator from my '78 F-150. Is this perfect or what? Now I just need to figure out which wire goes where....
-
thanks hydrocars, I'll get one this week. Try to get 3000 to 3500 at the alternator

i like the first one... there is 2 ways to get 3k rpms on that alternator, the first is to use a 3k driver motor and 1:1 pulley ratio,, the second is to use around an 1800 rpm motor and use about slightly bigger pulley on the driver motor and a smaller on the alternator,, i have not tested the 1800 rpm yet.

hi
I can send you a picture of a motor that I have wich goes to 2700rpm and on the motor is a litel stick with which you can control the speed and the side of rotation (left or right) I will take the picture tomoorrow and postit to you

Hey everyone. Im kind of new to this, but have been reading alot of info. One motor I came across that I think would be good is a treadmill motor. I just aquired one. It is 2.25hp at 130VDC and it outputs over 7000rpm. The motor is a varible speed motor and comes with all the gadgets to make it work. With some tinkering you could possibly dial it in perfectly to the right rpm. Im going to give it a try. I will update you guys on my finding.

What is the best approach for the individuals who do not have variable speed driver motor to regulate the rpms?
The full on, full off deal is killing me.
-
Buy 2 adjustable pitch pulleys. You can vary the RPM's by widening or narrowing the pulleys, while they are still on the shafts.

You can purchase one of the 3 or 5 step pulleys like they use on a drill press. If you do that you may also want to consider using an idler pulley that you can adjust back and forth to tighten the belt. That way seems less expensive too but it has the draw back of a little inconvenience in adjustment while testing your circuit.
