Phase converter OK to power 2t22A? A= three-phase motor

[Robert Gift]

I want the 2t22A on our fire station's roof.
Roof is high location and siren would be proudly on display.
A utility pole would be very expensive to purchase and install.

But Xcel Energy says we cannot have three-phase at the same building which has single-phase.

Can a rotary phase-converter work?
On YouTube, was there a 2t22A powered by a phase converter?

At $1,500, the rotary phase converter would be half the price of a pole.

Any other ideas?
Thank you.

There are also electronic phase converters, but I've never seen one used on a motor that large. The siren would probably run a little slower, making it sound as if it were running on 50 Hz..

I'd be happy if it wound up a little slower.
But it should attain the same rpm.

Robert, I may be repeating a question already asked and answered but, would a pole be any more expensive than having a crane and electrician(s) out there putting that thing up there plus the cost of the phase converter and transformer? I didn't know that poles cost that, I thought they cost a good $600 if you go to the right place. Again, sorry if this question has been answered but I haven't been reading the forums much lately.

A rotary phase converter with a 15hp slave motor should do quite nicely for that application. And with the right transformer you can step up the voltage if needed.

Acquiring, transporting, augering a hole and planting a pole will be quite expensive. $3,000?
I'll do all the electrical work myself.

But I would prefer the siren on the roof where it is accessible.
Once on a pole, I can't get to it and experiment with it - like set smoke bombs off below and see if there is a vortex into the lower stator intake, etc.
Also, if we paint it fire engine red, we can't touch up without a bucket truck.

A rotary phase converter would allow the siren to be mounted right on the roof for accessibility and maintenence and it would look good. Well, as good as such an ugly monstrosity can look.

Thanks.
What does the "slave motor" do?
This siren is wired for 208/240, so the 240V single-phase voltage will be sufficient with no need for step up.

This might be of interest, Robert.

At the Fort MacArthur Museum, they operated the 500AT on a small phase converter. I don't know the specs on that converter, but it wasn't huge.

So a converter should be your best bet, I think.

Maybe this is why it should be mounted on a power pole....
