| TOOOOOooooooooo Coooolllll!
The turbos needed to be re-worked after I got them
from the supplier as the performance was poor to non-existent. After
that was done, a circuit was made to change the 3-phase AC to DC (thanx
Wayne for the help). The 3 AC wires from the turbo are attached to the
center of the circuit board (as in the picture). There's 9 terminals in
the center for the 9 wires (from the 3 turbos). The DC output is at the
ends. To run up the turbos, compressed air was used. Winding these
things up is pretty cool. They make a whining sound, especially at high
speeds. They put out about 14VDC at 80psi. The DC outputs will be
attached to the battery to charge it. The air compressor (which is used
for the air brakes), runs the battery down after about 8 hours of
running. With the turbos charging the battery, that shouldn't be a
problem anymore.
Here's the circuit board. I just bent over the
diode leads and soldered them together.
 
The total cost for the electronics
was under $10 (and that was for all three turbos)

Here's a circuit diagram for one
of the turbos (3-phase AC to DC)

Here's the turbos hooked up for
steam and all the electrical wiring done. The white tubing insulation
was used on the steam lines. Copper tubing was used for conduit to run
the wires through.
