Hello All,

Now you can beleive this or not, I don't care.    I'm telling the truth.

Well I worked all day yesterday and today.    I finally got the motor
running on all three valves, with the points.  At a one hundred volts DC
the motor draws around .50 amps.   I can pull it down to about 1500 rpm at
.50 amps, thats only 50 Watts.    The cap I am running to stop the ark on
the points is 6 in serious, thay are 33 MF feed through caps.   With 6 in serious
that means that they are about 5.5 MF.    It is running real good at 100
volts DC.

Now here comes the good part.   I increased the voltage to 150 and the motor
really came alive.   It ran at about 4000 rpm and was only using about .50
amps at 150 volts dc.   I tryed to pull it down and maybe I could knock of
around 500 rpm(3600 rpm) and it still ran at .60 amps at 150 volts dc.  Thats only 90
watts of power.

I set up a 1/2 hp motor that ran around 1500 rpm just to test the power I
could stop the 1/2 hp motor with a pair of lether gloves.    With this new
motor I could not stop it using 100 volts DC, I could only pull it down to
around 1500 rpm, that was only 50 Watts..    Now running it on 150 volts DC
I could only pull it down to around 3600 rpm, only .60 amps, that was only 90
watts of power.

I think I may have wound the coils with to small of wire.   But maybe it
will be just right with the controller.  I think we may have a winner
here.   Honk wants to leave the coils the way they are for right now, for testing
the controller.

Sounds amazing, Jack!  You must be really excited!  Sounds like you should easily be able to go closed loop with any old generator!  Go for it!

Hi Jack,
Looking good mate! Keep us informed.
I was wondering, what is the size of one air gap on your big valve system?

Thanks!
