New York subway system at one time or another was powered by similar setup my understanding during world war II this was highly protected piece of equipment, if someone were to throw sand into coils this would destroy everything.
It probably is something along those lines. Synchronous motors this size need a supplemental source of torque to get going up to speed before they can run sychrnonously, so I'd imagine what you can hear is the switch from start up to full synchronous motion.
It's driving a huge piston pump on the left side with about a 4 ft diameter crank and a piston about 2 ft in diameter. A smaller crank arm visible on the outside to the right is likely a slide valve. The large overhead cylinder at the back is a gas accumulator / bounce / buffer tank.
No a compressor doesn't need a synchronous motor, they are using the motor in two ways. This is a large factory by the look of it, they use the rotation of the motor to drive an air compressor to supply factory air, also by varying the rotor excitation, you can just see the copper slip rings near the wheel spokes, they can also correct the power factor of the factory so they reduce the factory line current. Another name for these motors is 'rotary synchronous condenser' Those old engineers were way smarter than they are credited.
@@jeffcarter4881 It looks like a single cylinder reciprocating compressor. I guess that explains the huge flywheel, to add momentum to the rotor of the motor, which is already huge!
That sound of this motor starting is just amazing, so much power :D

Thank me later (: Wait till the end of the video.

RIP Ed, always good to see your comments around

@jameswheeler5025 sad story
I love those big vintage electric wagon-wheel motors. I've seen a few of them up close, in operation
nice to see and hear, we love big electric motors
Menzel get back to work on your motors, i see u in youtube comments too much lol
Completely badass! More video of it please, including more detail of what it does. And a shutting down of it would also be most watchable
WOOW. SO VERY BEAUTYFULL STARTING SPINNIG UP SOUND❤❤❤
Looks like it is running an air compressor
That huge wheel spinning terrifyingly fast
I love that sound
oh that's why my lights dimmed
I cannot imagine what this could possibly be made for other than like, a boat
It's driving an air compressor. Factories and especially mines would have a few of these for running machinery or drills.

what happens at 0:55? sounds like a switch closing (locking the rotor to synchronism once at the right speed, perhaps?)

I think the motor was swiched off because he begins to slow down.
love it......
It looked like a game in the thumbnail ngl
Is that Frankie Boyle starting the motor?
your electric company must love your for the inrush current
what were these motors used for?

Is this at Missouri Mines State Historic site?
It is the historic former Bethlehem Steel Facility at Pier 70, San Francisco.
Very cool
Das kann doch kein Synchronmotor sein. Wie soll der denn aus dem Stand so starten?!
Ich sehe keinen Hilfsmotor, der ihn antreibt.
I think I just came
why would an air compressor need a synchronous motor? Is the speed that critical?
Simpler design, since it just follows the mains frequency and doesn't need control circuitry.

@@raygale4198 Thanks to you and to blitzcaster!
...wow....
What's that huge wheel for?
I think it's a flywheel.
im sure noone searched for this
Why is everyone getting a letter with a colour? Its weird and not cool!

Dawson Gilligan I just don't like it :(
is this an air compressor unit?
It's a Chicago Pneumatic air compressor unit which is not connected to the motor allowing it to spin free.

i seen this in l4d2
