Heh, these kinds of motors are always fun, especially if you have onsite backup generation. We used to have a 2250HP centrifugal chiller that when we started it up it would piss off the hospital because it dragged the whole grid down so bad their emergency gens started up.
Wow a long start. A company I worked at had an old 1950 motor on a belt drive refrigeration compressor that had such a cool start up sound, we would turn it of and start it many times a day. It had such a thick iron casing it hardly got hot. Great 50 year old motor.
@@ComidaDelBrain 72 is closer to 50 than to 100. Also given the original comment is about a company OP _worked_ at, it could easily be around the year 2000.
I worked in a power station years ago and part of my job was starting the four big fans ( two induced draught and two forced draught) after setting up the air path dampers and before lighting the heavy oil burners. Always impressed by seeing the ammeters maxed out for several seconds before settling back to their running amps. I can't remember the current, but they operated on 6,600 volts. Thanks for the video. Happy memories!
hahaha, this is the main motor for the draft fan at HP-3 at the Martinez PBF plant! I worked there as an I&E tech. This exact motor failed to start multiple times during the shutdown we were trying to come up from. That shack on the left is the stack air sampling shack for emissions monitoring, and I led the team that installed all the new tube for the air sampling from the top of the stack down to the shack itself.
One of my previous workplaces had 600kW electric motor with I believe star delta starter and it was running refrigerant compressor. It was located in relatively small room and even when I was wearing hearing protection it scared me every time that thing started. That sound was raw power!
I have a couple videos on my channel including one where a 200hp motor was in a hung start condition for about 4 minutes, the soft starter locked up and wouldn't open up, had to open the breaker.
I used to be a generating station operator for the Los Angeles DWP. I worked this steam electric generating stations for 34 years. So I am familiar with the startup of these large 4160 volt motors. When we were starting up a unit these large motors would peg the ammeter for many seconds. They would also slightly dim the control room lights when these motors were started. Also these motors made a lot of noise when spinning up to speed.
Heh, we had a big 2250HP centrifugal chiller to produce chilled water to cool a campus, on which had a hospital. That hospital would get pissed off because the starting of that motor would start their emergency generators because they thought the grid was about to go.
Those emergency generators controls would detect the sudden voltage drop and trigger an automatic startup of the emergency generators. At least that showed that the emergency generators were doing what they were supposed to do.@@literallycanadian
In the days of Stanton working I used to pressure wash the fan down every week to help make sure it stayed in balance. On more than one occasion they switched the motor on and it exploded. In the end they took to putting new parts in every time to prevent it as it was cheaper than repairing it once it went bang.
Could not skip the ads, never got through to actually watch the clip in the end. Tell youtube the oppressive ads are stopping me watching your clip which looked cool.
Or at a mine site where they start up local generators to support the mains while getting the motor running. BHP used to (may still) do this at Roxby Downs when starting 11 KV ball mills DOL. People at the next town (Woomera) about 80km away used to complain about the power dips before they installed the support generators, a pair of 3608 Cats
Did they walk away because of the noise, or just in case the fan exploded while starting up? (I've seen some photos of what that looks like and it isn't pretty...)
imagine the diameter of the copper windings of that motor Without doubt, Tesla is the best inventor of all times, just think about how many things use AC current or AC induction motors
I just done a quick search and it's actually surprising they aren't as big as I would expect they are only around 10mm - 12mm ø I was expecting at least 20mm ø
@@madeofscars9355 still too big for an electic motor I do induction motor rewinding on my school, and usually we use maximum 2.50mm copper wire Currently I'm repairing one that uses 1,45mm on work field and 0,45 on sarter field, its one of those centrifugal switch motors idk if you know them
And if you have heard of war of the worlds it sounds somewhat similar and a game based of it uses an industrial electric motor for the alien machine start up
That winding up,is that the starter? Or the engine itself? It starts so smoothly,no sudden bang from the cylinders. What kind of "Engine" even is this am curious.
So that's what this is? There's one near my place and I was scared for my life the first few times I heard it thinking it's an emergency system alarm or something
Well yes but more to the point the unit they serve is kept running unless it trips for some reason in which case the problem is fixed and the unit restarted. In our case a production run was 3 years between shutdown and maintenance.
These large motors can't usually be restarted often. In power plants they run for extended periods and are only shut down when unit serves is taken off line. Wonder what voltage...thinking some are 13.8kv
If there were to be an electrical fault that's where it could happen and you would not want to be standing there. Lots of current rushing into that location.
Assuming it's running at the rated 2000HP; 1HP is roughly 745.7W, lets use 750 to make the math easy. So 2000HP is roughly 1,500,000 watts. So for one 24 hour shift, that's 36,000,000 Wh.
@robksquest1748 Yes and it's very needed because the big motor has no VFD or soft start so if you try to just power it up without spooling it up it would draw some insane current. The motor is 4000VAC 380amps
A 2khp turboshaft? Is it like a mini turbine like the apu of a modern jet liner? I just would guess the Blackhawks turboshaft engine is like way more than 2,000hp maybe I am wrong? Anybody got the gap in my unknown knowledge? Like I would expect like a piper turbo prop style small plane but need to be around 2khp at minimum???

Which was it, delta or star?
@@HerrDagerman It's a star delta starter lol. That's a thing. It starts it in one, then changes to the other, this reduces the start up current.
I've learned something new today. Thanks
@@DUIofPhysics Is the current reduced so the motor won't stall during startup?
We actually have multiple 2k hp motors on my unit, and for some reason, I still find this fascinating.

It's funny that most perfomance oriented electric cars have close to this amount of power, for example Rimac Nevera 1888 hp.

Not the torque though 💃🏻💃🏻

What manufacturer of SCR based soft start running that?
Do not know
2000HP electric motor?
What would happen if a motor is started with and without soft start?
An induction motor would draw too much current during a start without a means to limit it.
We had 3 500 hp motors to the same shaft, they ran a log grinder on Vancouver island, started quicker. Never understood why 3 motors instead of one.
500 hp motor cheaper than 1-1500hp motor, plus if one is down would most likely continue to work at reduced load
What kind of motor starting method is normally used for this power?
Step starter, old ones as long as your garage for 1-500 hp motor
@@luishuaratazo4721

If there were to be an electrical fault that's where it could happen and you would not want to be standing there. Lots of current rushing into that location.
