- Turn up your speakers! This is the 600 horsepower, 2400 volt AC Westinghouse motor that drives the hoist system for the Soudan Underground Mine near Duluth, Minnesota. The motor, along with all the other equipment in the system, is all-original from 1924. The motor is variable-speed and reversible, and can move the hoist cars at a maximum speed of 11 MPH.

I was there last month, I wanted to stay in that engine/lift room for hours!!! I loved it there.
You and me both! it was magical, the sound is amazing.
The sound is almost as good as the ride, which is mindblowing!
What an awesome machine and fantastic sound.
Isn't it amazing? I really want to go back soon!

Please do, and make another video of this beautiful motor.
I will definitely be making another video with my new camera if and when I do return, in full HD with stereo sound!
SpeakerPolice
Awesome !! look forward to it.
RODALCO2007 yeh the sound is just amazing!, I love vintage Westinghouse equipment!
That is just magnificent!
I just picked up a very old open frame Westinghouse Generator and all I can say is that Westinghouse build their equipment strong!!!
That is a BEAST.
You can say that again! I saw some older Westinghouse motors the other day. Smaller than this, but still built like tanks!
I've been there and I've used the elevator. It's a fun ride.
That'll be cool. There's also (may or may not be visible in this video) a huge GE synchronous motor for the now-decommisioned air compressor that ran all the air-powered mine equipment. It looks like a gigantic ceiling fan motor, LOL.
Yeah, I do regret not being able to see more active old equipment, especially these old motors and steam engines.
That's way cool. Love the startup
oh i love the motor start up sound
We have a compressor plant on 6000 level decommisioned ( to hard to get enough cooling air in an already hot mine DUH )5 2000 HP compressors. On surface we have 4 3000 Hp compressors in service the Centac compressor ( decommisioned ) and diesel back up ( don't want a power failure and loose air for the refuges station if there is a fire ). There were 4 other compressor plants all decommisioned going back 100 years at Creighton
What a beautiful machine!! You CANNOT BEAT OLD SCHOOL!! I only shudder to imagine a dog test on that thing though I would pass the chance to experience it. It's not like the double decker 110 man cage dog checks that I'm accustomed to working for MAGMA Copper in San Manuel, AZ. The 2 3/8 cable would stretch like a rubber band for about another 30 or so feet. The FPM on those were about 1500 or so.
I stared at various mine hoists for 15 years ,from 200 hp ac to 6000hp dc
Isn't it? XD I think that motor is the best-sounding electric motor I've ever heard.
You got that right! They packed us in there like sardines and it was super-dark and noisy. It's a good thing I'm not claustrophobic! XD
I love to write sci-fi, and these are just a few fragments of a huge fantasy universe I'm creating.
I'm on strike right now but when the dust settles I will make a quick video of the 1939 Nordberg internal hoist at the mine.
Its a bit bigger and decomissioned ( and not very pretty ) but its an interesting piece of history. Not many of these old hoists are preserved and running like this
Sure does, 2400 volts at 150 amps starting draw. It runs on about 50 amps at full speed. You are correct about the sound; it's wonderful. :)
AMAZING!!!! At 11MPH, the elevator travels at 1000 Feet/Minute 5 metres/second! :D
A dog check is when the tension brakes that dig into the guides are engaged by making the cage free-fall. its what keeps you from falling down the shaft if the main cable snaps.
Looks like a lot of allis-chalmers components on that hoist, saw a couple A-C diamond logos.
The hoist itself was made by A-C. There is one three or four times larger than this one sitting in Butte Montana in the Mountain-Consolidated hoist house.
That reminds me, they had a Caterpillar D337 diesel generator from about 1957 for backup power. Alas, the next scheduled test was the day after we left! D8
That's my favorite part. :) Thanks!
This sound like a supercar flying
It sure is!
That was Awesome !!
This is an interesting read!
The mine is not in active use, it was decommissioned in 1965. Everything is now for display purposes. I should have asked about the fire suppression gear, though. Never thought about that.
I think they're using star-delta start, @0:14 you can hear the delta configuration kick in.
It has its moments. Sadly we are in a rather ugly strike right now
Its the Creighton mine hoist. That mine is also home to a simmilar lab ( the SNO neutrino detector ). The skip side is the 7000 hp GE Dc motor with a Twin GE Siplac drives system ( 1970s technology ). Cage side is very New ABB 3 phase drive and 5000 hp synchronous motor.
I am not fond of the new technology. Seeing the Lilley ( red thing with the ball weights spinning ) turn brings back fond memories
Ahhh, thanks for clearing that up. :3
Specifically, this is a Westinghouse, built in 1924. It operates on a 2,400-volt AC line and produces the equivalent of 600 horsepower. Nerdy questions for the win! xD
The Somali woman at the controls madly stomps the pedal on the floor and claws at the escalator speed control. She drools and shouts with wicked anger and scorn that would make the witch in the Wizard of Oz blush. With her other hand she yanks and throws about the checkerboard floor handfuls of her graying hair with blood-soaked peices of her abaya.
I bet that's a cool job. =)
@mitchtay99 I begin firing grenades into the infernal portal, and the motor shaft finally comes loose, dislodging in a way that it slices through the works and simultaneously shorts out the wiring across all nine phases of the AC supply. One final atomic flesh-scorching KA-BOOOOOM and a shcok wave that blows me all the way to the bottom of the tunnel.
Indeed, thanks! :3
Indeed!
so loud, I was.. crying😢😢😭😭😭
Oh really? That's pretty cool!
The elevator cars themselves move at about 10-11 MPH. The motor itself turns at a maximum rate of 350 RPM.
It really is! :3
@mitchtay99 The blade weighs 18,000 pounds, and is balanced by two flywheels, one on each side, each flywheel weighing 36,000 pounds. The motor unit is 6,000 volts, nine-phase AC, and produces 4,800 horsepower. The maximum speed is 27,000 RPM, and the shaft must contend with an outward centripetal force of almost 250 million pounds.
Thanks ^_^
Great video! The gearbox main gear sounds a bit worn. You can clearly hear the rattling starting at 00:42. This happens because the teeth on the gear are no longer the same size as when the machine was new, causing vibrations between the teeth.
GuyT 316Welding I'd say she's doing pretty well for her age, all things considered :P
There is no doubt about it, depending on the age of the hoist machine. Until is just rattling there is no problem. The fun begins when such a gear for this kind of wear and tear cracks as for example on one of the three hoist machines in my home town of Idrija. :)
At 0:50, DAAAAH IT IS SOOO LOUD!!
That's how it would seems. But from videos like these it's the camera.
Wow that's an old hoist they have a Lilly system to tell them what level.
Thats good to have back up power.
Our hoists are too large for that ( and owners to cheap ). Climbing a man way sucks trust me
I hope they have a compressor plant at Soudan in service. Nothing more frightening than fire underground. I would not work in a mine without compressed air ( Seems to me that should be some sort of law in your countries mining act as well ).
You can get away with bottles for a while but that limits the time you can spend in a refuge waiting for mine rescue
I realize what's transpiring as I ride the escalator. I unload a 70 round drum mag from my AK into the machine, and the blade tips begin to fly off. White hot razor sharp shrapnel is flung downwards in the tube at supersonic velovities. The blade is now imbalanced and the whole tunnel begins to vibrate with a deafening roar and every bone in my body feels like it's about to shatter from the shaking. THe bearings are instantly glowing white hot and UV rays scorch my skin.
Right, I see. All this talk has reminded me of the Centralia mine fire. I wonder how long that will burn for?
Okay, this is an interesting conversation... xD
Is the excess noise from this motor just the magnetic fields its producing?, its still epic :D, even to this day :D
What type of hoist speeds does this get up to?
Awesome, isn't it?! =D
YAAAOOOUUU! >=O SO LOUD!
@mitchtay99 Short circuit across nine phases of 6000 volts AC, how's that for an arc flash explosion?
If I may ask, what is a dog check?
Just curious of what type of AC motor this is? (Yeah i know it's a bit of a nerdy question ;)
AND IT'S GOING 320RPM INSTEAD OF 350RPM
Why does this sound and look a bit like the frameshift drive
Correction. I wouldn't pass the experience of the dog check on that. Damned spell check. ;)
THE SOUND WAS SO WORST IT WOKE MY FAMILY UP!!
Very retro I like it.
I work on newer 7000hp version servicing a 7120 foot shaft.
But I realy perfer the old hoists. They speak to you when they run if you learn to listen
Correction: I WOULDNT pass up the dog check experience. Damned spell check!! XD
We get in a refuge in a fire crack open the compressed air line and clay the door.
In the unlickely event you can't get to refuge there are canvas bag fresh air stations with compressed air lines, portable refuges with bottled air. In the worst sittuation you rip down some vent tube and wrap it around an air header openthe valve and get inside.
If you can't do these things well you die in fire from CO poisoning.
If its obvious you can't put it out run and call out fire on the radio.
@mitchtay99 Meanwhile, In another community center, a large number of sewing machines are stored in a basement room. It's a hot July afternoon. Someone has spilled a bunch of cans of cheap store-brand soda pop all over the room. In the darkness, the walls, floor and ceiling are moving with a mass of millions of black ants.
Have you seen that somewhere? That would be EPIC. (but very bad! xD)
TURN DOWN YA SPEAKOS
Moter Sounds scary
I think it sounds amazing!
سكس
The screams of the machine are turning into an excruciating and condescending groan. It sounds like diabolical howls from the deepest part of the lungs of some female minotaur giving birth
There is a group of Somali immigrant women who meet for a sewing class in a community center in my city. I've developed a bizarre fantasy about that. The Somali community announces an event where white men are invited to meet Somali women. The white men are led to an escalator, which goes up and up a long narrow tube to a giant shredder at the top. A Somali woman sits at a control panel that looks like a sewing machine, staring into the shredder chamber through a heart-shaped window.
Ik this is 14 years ago but are you alright?
Look up the Wankie mine.
Chain of events is clear but at the time they thoughty nothign of the minor incidents.
She looks at the flames through the chamber, smells the electrical wires burning, and sees sparks flying from the control panel, and issues a furious moan of rage and spite, and doubles over on the floor, breaking down into a sobbing heap.
(bangs his head on the door2
@mitchtay99 White American men eagerly line up to get onto the escalator. The escalator goes upwards through a narrow tunnel, dimly lit, with pink and lavender walls. The escalator handrails are a velvety soft chocolate colored rubber. The steps are shiny blue-tinted steel. The escalator tunnel is so narrow and long that it's difficult to see what's at the top. The white men assume that they will enter a room full of Somali women who want to marry them.
Blinding flashes ensue as the 45-ton mechanical assembly rips itself to shreds. Watery-thin rivers of pure white molten steel pour down the escalatorsteps, causing the steps themselves to melt. The chocolate-rubber escalator handrails are turning into slippery flaming globs. I am deafened by shreiking and grinding noises. The blinding molten white colors are beginning to redden, as the machine begins to bind and slow a bit.
FI YA! IT'S SO MUCH SPEAKA POLICE! I UUUU, UUUU, 🤔😒🤔 DUNNO....
Plz stop Plzzz PLZZZZZZZZZ!
