Generator set up and running now with moving pictures

Rolland · Dec 4, 2009

This started out as a double cylinder engine that Brian had drawn up. Then I found the PM site and picked up the generator. Things just went on from there. Having been in the stationary generator business for many years this was a given. Thanks to Rustlolector for giving me the idea of how to put the engine to work.
I have it putting out 4 volts right now but still need to work on the pulleys and get the speed up a little. I may also have to rebore the cylinders to either 5/8ths or perhaps 3/4 to get a little more power. I am using a big drive flywheel hoping it will retain enough energy under load. I am waiting for Radio Shack to get in the other lamp base and bulbs. I will get a video when I get the load bank on. Meanwhile here are the photos of the set.

Nice looking group of models.

Just turn that pulley post set up around. Should double your speed on the genny by the looks of it.

Hopefully I'll get my generator finished before the kids graduate.

Excellent work,
Kermit

Roland--Don't be afraid to crank up the pressure on that engine. I have ran mine at 60 psi. with no problems. The governor will keep the engine from "running away" if you have it set up right. You shouldn't need to rebore the cylinders.---Brian

You may want to have a look at this site:

http://www.modelenginegenerators.com/Home/generators---model-gas-engines

These put out up to 55 volts. Mine will put out 16 volts at 400 rpm. Way more power than the PM research generator that I built, and at a lot less RPM.
The engine running a train on the website is mine.

No other photos, never thought to do any until I was finished. :

I have been working on the setup for the past couple of months. I will get some running when the load bank is finished.

I am running 50 pounds right now and the motor seems to like it. at least its not complaining. I may change the govenor spring as I still have some room to go there. All in all its a really nice design.
