Steam Turbine Stator

In the above picture you can see the stator windings and the four magnets pressed into the rotor shaft.

The pockets for the magnets were cut in on my little benchtop CNC and utilizing a new index fixture I just got off e-bay.

This is the stator core being profiled out on the one half. The program I wrote for this operation had about 6 lines of code, going from the 12:00 position to the 6:00 position in .007 steps.

The original magazine article called for these laminates to be backed by thin plates. The only problem I had with this is that most small endmill cutting lengths are only 3/8" unless you start ordering special tooling.

For the past few months I have been searching for plans to scratch build a steam dynamo. I came up with some rough ideas but it just so happened that in this issue of Live Steam there was an article/ project of a Pyle turbine. So here are some pics of my version of this project. Of the changes I made was to the number of fields and magnets. Instead of two magnet positions, I made four and instead of two windings I put in four. I'm hoping for a little more output with less steam input. I appoligize in advance for some of the pics. They were taken with my cell phone because I was just too lazy to fire up the good camera.

I know...lesson learned.
