George,
Keep reading the list and see the below file. You guys have
free
motor power here. Here is a powerful fan.
This is the biggest Brushless motor to date. Still looking for
a
really big one. This was a 24W motor, I would like to convert
a 240W
motor or larger if anyone has any leads or one lying around.
I had to use two of the coils in series for the trigger pulse.
Starts
really easy. Lots of flexibility with voltage and amperage
variation.
I have a capacitor bank pulser on the back end so that I can
rotate
my batteries around, and also two DPDT switches with center
OFF
position so that I can switch either battery banks from
charging to
discharging or discharging to charging. The off position in
the
center allows for no shorting the batteries. Should really be
only
one 4PDT switch but I didn't have one that small on hand. What
you
don't want is to switch both switches in opposite directions.
I spent a good part of Saturday finding parts to use and
assembling
it. At first I had it so that I could switch from using the
original
circuit over to using the Bedini circuit. But I must have
shorted out
something as the original smoked, so I removed it. It would
have been
a nice demonstration to flip between either circuits to show
the
difference. I may still do that with another one of these
fans.
I can make these available if there is enough interest. The
only
drawback to this motor as an energizer is that it chirps and
can be
annoying at the lower amp setting. The advantage is that it is
perfectly machined and there is no frame and rotor assembly
required.
It is a little more involed in dealing with the wiring, but
with this
bigger size it is not that hard to access anything.
If made available I would send all parts, with the full
details of
what to do with the fan. I would leave the fan with original
circuit
so that people could first test it for comparison, but also
give the
Bedini SGS circuit as in the other kit (without the rotor and
magnets). I got the plastic bottles today to send the lube
with any
new kits (once the lube arrives). Price would probably be $150
to
$200 depending on what was sent (like box, switches, wires,
cap,
etc.).
In the picture you can see a small circle on one blade. This
is a
tiny neo magnet for rpm calculations. I'll just add a small
coil or
wire to pick up the signal on my oscope. I also have one on
another
unmodified fan to compare power consumption at same rpm. I got
a
bicyle speedometer for this but forgot that it stops at 99.9
mph so
it was only good for the larger wheel monopoles. I will test
these
motors with both hooked up to batteries with clamp amperemeter,
also
with power supply hooked up to watt meter, also going to a
home
electric company kwh meter and note the differences as I did
with
previous brushless motors and monopoles and etc.
