what is the cheapest Generator to buy?
« on: February 16, 2005, 02:20:21 AM »
I would like to know what Generator to buy. I dont want to make my own since the magnets are alot of $$$$ and I am only 14 and money doesnt come buy that easy.

I would like to have a sealed dc motor that can charge a car batt or run 12v lights.

I like AMETEK motors but their too expensive. Is there another cheaper low rpm Generator I can buy?

thx nick_02

If you're short on money, perhaps you could have a try at building something like this?

Ed says that it cost him a total of $8, and dead microwave ovens are pretty easy to find.

Get one of these maybe you can get it free...

 Take the blower part off, make a 2 inch wood disk with a hole saw, tap the wood disk onto the

motor shaft, hook it up to a 12 volt clearance

light. Turn a bicycle upside down and have a friend crank it while you hold the motor pulley

against the tire...see what you get and go from

there!

                 Have Fun

Anyone else done any experiments with these types of automotive motors?

How about $10 + shipping for a treadmill motor?

It reaches 12v pretty easy.  A cheap place to start.

I bought a 38volt ametek motor for $36.00 with s&h.

cant wait!

now i'll need to work on the blades (I want to use aluminum blades hopefully) and find some way to make a pivot.

Where did you find that?


Some (most) people don't think metal blades are a very good idea.


You should do a search of this board for 'blade design', 'Zub-Woofers', and maybe even 'Sputnik'.  You can make a decent set of blades for about free.


Search 'yawl bearing'. There are some easy ways for that too.


Have fun!
