I’m a fan of the theatrical startup! Curtains open on a lonely fan. Dance starts, slowly building tension. Video cut short right before final climax! What a performance! 👏🏻
ahhh, but don't forget the 'reluctance' - thats the 'eeeck' of the massive bearing not wanting to move right at the beginning of rotation! i'm thinking Vincent price!
With huge machinery like this, electrical efficiency and power factor are very important. The driving motor probably rated at just enough power to keep the fan at rated RPM, hence the slow start-up.
actually, i think i hear a VFD solid state type device - the original would have had reduced voltage starter (delta/wye) - you can hear the very high freq harmonics.
very cool! my company did the test rig for a navy pump supplier 4160 with a vfd - have you worked with higher voltages? thats the highest i have seen - i know they are now 13kv or so@@AtlasReburdened
also -what's so cool? Hearing the massive bronze shaft bearings breaking 'stiction - when it first begins to turn and getting their lubrication film built back up -anything larger has a 'turning gear' that must keep the shaft turning slow -to keep this film intact@@AtlasReburdened
The boost is amazing, but the turbo lag on the spoolup time is terrible. Imagine the race though, the other guy sprints away from the line, and is less than 100' from the finish, and you come blacking by as the turbo finally gives you the boost, passing him at Mach 0.99! 😂
@@ponponpatapon9670: 1. You can't know what other people would think until they tell you, because you're not a mind reader. 2. Nothing I asked him qualifies as so-called "pedantry." 3. You aren't still person I was even replying to, so you don't have to worry about it.
Yeah, that's what I thought, too! How come he cut it off right here? It took so long to speed up, too. Even as heavy as that motor shaft and those blades are, I'd think such a big strong motor wouldn't have such a soft start... even on a soft starter.
Can you imagine the startup current that thing must draw, and for the length of time that it takes to start it? And it actually seems to be underpowered. A bigger motor would probably start it faster and with less energy use.
I'd imagine to keep the duct sealed, to keep air from blowing out or being drawn in. If you're running another fan somewhere a few miles away, you want the air to go the full length of the tunnel and not out earlier.
I don’t know why but there’s something really creepy about this. Like imagine you’re walking through a dark building and this big ass thing is at the end of the hallway running full speed
With any fan, the energy required (current in amperes if electrically driven) at the initiation of start up is to overcome the static inertia, plus friction in the drive system. As the machine rotational speed increases, the air it now begins to move creates resistance, which requires proportionally more energy, until the maximum rotational speed is approached, at which point the turning force, or torque, should remain constant. It is the opposite situation (regarding starting from standstill), to a motor driving, say, a compressor, lathe or other machine, which requires an initial high starting torque, or electrical current. BUT...... you already knew that, I would have thought....(!!)
Hat-tip to the lads at Metro-Vick for a gearbox that will be around in 200 years. Still working. Probably still ramping up to operating speeds. (a VFD the size of a city bus...)
This is so scary. I have been 100m close to a water pusher ventilator that was 1 metre big I think, ang it was scary to hear that. I cant even imagine being close to that
The sliding gate really deserves a badass loud deep beefy military-base-ish buzzer alarm.
Stargate SG-1 might fit the bill ;)
Portal 2 vault door moment
In stereo
DRRUUUUUUUUUUUUUUUUU----EEEEEEEEEEEEHHHHHHHH BLA BLUMP CHUUUUUUU PSIIIIIIIIIIIII

"Always leave 'em wanting more!"
I'm a big fan of this video.
Beat me to it, lol
I think it blows
Yes, so much fanfare over the fan😂
Honestly they suck me right in.
I , am now a fan club member .
Fantastic! You couldn’t put a better spin on it.
Haww... HAWWWW!
FANtastic
This blows me away !
The softest starting motor that ever lived.
Should just go across the line, dim the lights in the city !
They painted it red so that when people get sucked it in, the splatters on the blades dont traumatize the other workers
Whats about the body part?
Planning ahead. I like it..
Thank you for not adding music to this

@@prestonburton8504I'm certain that you're correct. I repair drives for a living and recognized the sound immediately.

The fans connected to a worm gear
I feel robbed, the video should have gone on another 3 minutes
Yes, it was a real blow that it stopped when it did,
No reason it couldn't have continued. Prob deliberate. Thumbs down and unsubscribing.
Mersey Tunnel fan ten hours for study
ruclips.net/user/shortsLrblkukd6wA?si=8CKm7M19j_cfqm6A
They should start their own Fan Club.
You've got what you want, Cohagen! Give these people air!
LOL I couldn't help but reading it in Arnie's voice in my mind. 😂
lol
Two weeks....two weeks😮
See you at the party, Richter!
Open your mind
Warning: Do not lick while spinning!
This is not sex toy so men don't go sticking ur talley wackers in there
Now that's a turbo for my truck
The boost is amazing, but the turbo lag on the spoolup time is terrible. Imagine the race though, the other guy sprints away from the line, and is less than 100' from the finish, and you come blacking by as the turbo finally gives you the boost, passing him at Mach 0.99! 😂
Finally, a fan to cool my pc
The intrusive thoughts are telling me to jump into it
Well you aren't jumping in it, so you're a normal guy. Everything is fine with you.
You can do anything you can dream of in this world, if only once
THAT IS INSANE!!!!! Thanks for sharing this. I'm a huge fan of giant industrial/municipal machinery.
Magnificent piece of engineering. The rotor weighs several tonnes and is perfectly balanced.
Its creepy being so giant
Big machinery really is. Especially if it's automated. It's just so impersonal.
Why is that so... "creepy"? How does it supposedly feel like some crazy creeper skulking around?
@@HelloKittyFanMan i think everyone who isn't a pedant automatically understands OP means "creepy" as in the 'menacing' sense of the word.

It really is for some reason.
Safe to say I’m a heavy metal fan.
People actually get to work there while I have to sit in an office, it’s not fair
Not too late to learn a skill!
Those doors opening reminded me a lot of portal 2 for some reason.
Definitely a scene from Half-Life.
Perfect place to throw a couple head crabs into
Would’ve said portal 2
Nah.
Fan-tastic! :)
would be great to see full speed
Yeah, that's what I thought, too! How come he cut it off right here?
It took so long to speed up, too. Even as heavy as that motor shaft and those blades are, I'd think such a big strong motor wouldn't have such a soft start... even on a soft starter.
thinking about it now , every one is standing in that fan room and if they speeded up the fan it could suck every one in. ????????
@@HelloKittyFanManYeah. Lame!
Nahh, @@wayneheigl5549, this isn't like... some big jet engine fan. You'd have to be a lot closer to this one for that to happen.
Yes, but that culd be the full speed. Boring IK, but could be pushing insane amounts of air
Aww you cut the video during the climax 🤨
I didn’t know they had tours of Michael Moore’s bathroom fan. Amazing!
😂
So does it go faster?
Played in reverse would be a scene from Total Recall
I assume if cranked on high it will blow tons of air
Fascinating that most mechanical machines involves the spinning motion.
What a big fan and it's very quiet operation but why does it spin so slowly and I thought it was a high RPM fan and what is fresh air intake?
The perfect fan for this summer.
How much $ ?
Now that's a big heavy metal fan! 🤙
Those were some serious beef curtains
What's the max speed of this thing?
I'd like to know what the point is of this sand in the first place
Can you imagine the startup current that thing must draw, and for the length of time that it takes to start it? And it actually seems to be underpowered. A bigger motor would probably start it faster and with less energy use.
Is that the fan for the whitehouse diaper room?
Yep Trump had it installed.
Turbines are into all sorts of music But they are huge heavy metal fans
"Pleased to finally meet you, I'm such a massive fan!!"
Why do they close those doors on it when it isn't running?
I'd imagine to keep the duct sealed, to keep air from blowing out or being drawn in. If you're running another fan somewhere a few miles away, you want the air to go the full length of the tunnel and not out earlier.
I don’t know why but there’s something really creepy about this. Like imagine you’re walking through a dark building and this big ass thing is at the end of the hallway running full speed
Why don't the blades have more of an angle to them? It seems like it wouldn't be very good the way it is
He's a big fan of ur video
Each blade are red😂
Where is this? Britain?
Liverpool.
Is this for a traffic tunnel?
What does this thing do? Fanning what?
Me when I fart,,,lol. Really it moves fresh air through the tunnel to help force out car and truck exhaust.
Only question from me......
Why aren't the hatches open 24hrs ?
With any fan, the energy required (current in amperes if electrically driven) at the initiation of start up is to overcome the static inertia, plus friction in the drive system. As the machine rotational speed increases, the air it now begins to move creates resistance, which requires proportionally more energy, until the maximum rotational speed is approached, at which point the turning force, or torque, should remain constant.

BUT...... you already knew that, I would have thought....(!!)
Ant to think I tore myself away from watching paint dry for this.......
Where is part 2?
I used to love things like this,but now im an extractor fan.
To be honest I was a bit underwhelmed. Cool machinery tho!
"COOL"! You're sure you're not a... "FAN,"... eh?
@@HelloKittyFanMan I wasn't exactly blown away by it
@@supergub: HAHA! 🌬️🌪️ But it was the thumbnail photo that sucked you in, right? 😂
Yeah, this video had so much promise but it turned out to be just a lot of hot air.
It was a shame the video stopped before the motor was up to speed.
Hat-tip to the lads at Metro-Vick for a gearbox that will be around in 200 years. Still working. Probably still ramping up to operating speeds. (a VFD the size of a city bus...)
This is so scary. I have been 100m close to a water pusher ventilator that was 1 metre big I think, ang it was scary to hear that. I cant even imagine being close to that
that's a big MFer and i've seen some big fans that's bloody massive
What kind of tunnel is it
Road. Queensway tunnel, runs from Liverpool to Birkenhead.
The purpose of this is?
Air flow
How fast does it spin 100rpm ????
This is how fast it takes my RV to get up to speed when getting on the freeway.
This is taken directly from Portal 2
this might effectively cool my 3090
Does it ever finish starting up?
1.21 Gigawatts! What was I thinking?????
I was not blown away by this video. Very disappointed by the description, it's just so much hot air.
Ants when you turn on your computer
Rumor has it: this fan still hasn't gained the full speed
Been there. Seen that. Stood in just about exactly that spot.
Now THAT'S a fan
You can hear the whine of the VFD carrier - Imagine soft starting this before the VFD? Probably huge resistors to get it going initially.
FANtastic!
Why so long to open? should've been air piston operated.
I've never heard of this before. What are the parameters?
very large
I’m a huge fan
I bet National Grid notice when that gets turned on.
That was interesting. Thanks.
pretty sure this entire process was designed by Derek Meddings!
Now that's a big ass fan!
Fantastic!
Hubiera sido interesante ver el motor o motores que mueven ese ventilador a través de esa caja de engranajes...
I love big machinery
Its kind of scary looking. Door opens and there's a giant spinning red fan in a black hole
"I'm a huge metal fan"
I don’t even think it hit 1 RPM by the end of the video
I need this for my bedroom
can this air cool an i9
Looks like it could use a bit of a clean.. Who wants to volunteer I promise it’s turned off!
I wonder if this fan aired on tv, it would have blown the ratings by putting a new spin on things
This looks quite scary
Why is it so slow
I thought I was looking at a nautica fan for a moment
That's one hell of a salami slicer.
why dose this remind me of the thing that opens the vault in fallout
That's a soft start
A bit too soft, the motor windings should be groaning during a proper startup!
Stand by for lift off
What a letdown. I want my 2:37 back.
Me to it was building up than video stopt
Anyone else thinking what happens if that chain gets to close
Is it just me, but did anybody else feel like they got all worked up for nothing? Its like being married!
Cool
