I had expected to read a response from you concerning your more exact
needs regarding this "phase converter". Your project interests me, but it is
unclear if you are hoping for a donation, or if you have interest in
developing a power source for the sirens.
I'm pretty sure you could power your sirens with a much smaller rotary
converter. It could be a real learning project for some electrically
inclined young scout. I'd expect a little (5 HP) idler at each siren could
make all the sound you'd ever need.
If this *is* a real project where only the "results" (siren sounds) is the
goal, and no *overseeing specification writing group* of people need to be
satisfied, I'd voluntere my time and materials to a task like this. I'd
even bring some parts.

I'd sure like to hear more about what your 'constraints" are.

Hello,
First of all let me take this opportunity to thank all of you who
by virtue of reading this line have taken time out of your busy lives
in order to do so. I thank you profusely. I am working towards
achieving the highest rank and honor of scouting, by becoming an Eagle
Scout through completing a project as part of the Boy Scouts of America
program.

My project is rather complex in nature and by virtue of this fact
has been difficult to accomplish, with forecasted expenses the
government gave us that come in well over $50,000. For my project we
are going to take two Cold War era civil defense sirens and install
them in a small rural community in Arizona north of Phoenix called Mesa
Del Caballo which is near Payson Arizona, just for a reference point
for anyone who is actually from Arizona. This is a small mountain
community surrounded by the forest. Arizona has been going through a
massive drought over the past years, and as a result, combined with the
disastrous effects of the devastating bark beetle, our forests have
been highly susceptible as of late to pernicious wild fires. My goal is
to set up these two sirens in this community, one on one end, one on
the other, such that if there ever were a forest fire, or other
disaster which required a quick evacuation, the entire town could be
alerted via these sirens which would span all distance and language
barriers.

The government has been extraordinarily helpful to my project so
far by letting us borrow two civil defense sirens each valued at
roughly $25,000. Just to clear up a misconception we can only borrow
the sirens per regulations that were set up before the Cold War when
the sirens were originally installed throughout most of the greater
Phoenix Arizona area. The sirens we are "borrowing" for the project
should never need to be returned, it was just part of the original
contract in case of an extreme unpredictable emergency.

The problem we have run into is that we now have two Cold War era
civil defense sirens, but we don't have the money required to install
them. The representative from the Arizona Government estimated the
actual installation to be somewhere around $75,000. Our estimates upon
further investigation show it to be a smaller figure, but nevertheless
still a massively large amount. The two parts we stand in need of right
now are two 220 volt 50hp phase converters to go from 1 phase to 3
phase. These would be tax deductible, and we can provide proof of their
purpose for this project upon request. We are looking for a spare 50hp
phase converter that can be donated to our project. It does not need to
be new, used or surplus is absolutely fine. The exact specifications of
the civil defense siren are below:

We are starting off with a 220 volt, 200 amp, 1 phase line.
The siren we seek to power has three separate motors.
Motor 1 is a 7hp
Motor 2 is a 4.5hp
Motor 3 is a 1.5hp
RLA is 89amps, 220 volt, 3 phase

I was told by a specialist per these specifications that we needed
a 50hp phase converter. If anyone has a spare they can donate or knows
of a possibility for a donation, or can point us in the right
direction, or has any other helpful information for the project we
would deeply appreciate every little thing we can get at this point!
Thank you for your time in reading this letter. I deeply appreciate it.
