Perhaps I missed something but I don't understand the DC motor speed controller bit. If it runs on air/steam with a generator driven - why? OR is it a generator / motor thingy that you could use to run the engine that way if you had no steam or air?

Hi Andrew, Dave, John and John B,

Thank you all for the kind words.

John B,

The speed controller is used to set the excitation current for the generator which comes from an external 12V DC source.

Cheers.

Thank You Abraham,
           I Learn heaps from this forum. Even if I do sometimes have to use a search engine to find out what an "Excitation Current" is. And, from my quick reading I think it is used in generators without permanent magnetic fields. Looking at your generator I see both armature and field windings so think I got it somewhat correct. OR is a generator without permanent magnetic fields called a Dynamo? That's what was on my push bike as a kid.

Hi John,

There is a bit more info in the build log of the generator here http://madmodder.net/index.php/topic,11170.0.html.
