Those soft starters are really good. No shocks to the motor or spikes on the line. Perfect for hard to accelerate loads like large fans. Direct drive fans like the one shown are preferred for industrial applications due to the simplicity of construction and no belts to slip or break, but they represent a high torque load on start. Solid state soft starters are perfect for smoothly accelerating the motor without causing voltage disruption on the line.
Soft start are less energy efficient though. So there should always be a good reason to have soft start over variable speed drives as they are the most energy efficient.
@@Sunnfjordingen What are you talking about? VFDs use more power at the same operating speed when compared to a motor connected directly to mains with a soft start. VFDs always have to convert AC to DC, then back to AC. Soft starters only operate on startup, then it switches the motor to the mains. Unless you need speed control soft starts are the way to go.
That sounds more like a VFD start than a soft start. Edit: Soft starter video for reference: ruclips.net/video/KSHmA0vDnOQ/видео.htmlsi=6-hy8ZlkGeYmXq5A
Why does this actually sound like I'm standing on a Subway platform underground and the train just started up? It's like it's rushing past me and I hear it echoing down the tunnel and getting more reverb as it fades away
Because it's basically doing the same task, just this one has a huge fan to bring up to speed, and the subway has the subway cab incl. contents (passengers etc.) to bring up to speed. Notice how the ramp-up time is also very comparable.
2 questions: 1] What is the motor code on this thing - must be at least a J 2] Nobody bends 4/0 like that entrance - looks like rubber cord or welding cable - what is it?
I don't recall how big some of our fans are. I just remember standing in the plenum! It was a big gymnasium size room. There were 4 fans feeding directly into it.

So all this time, it has been just the motors, not the wheels and rails!
If to pumps always running, but there is different sound between this two one of them have like Winding sound what do you think it is winding problem? If you can give me the answer please, and thank you sir
Winding problem will be detected by the soft starter, so if it works don't worry about it. Small problem with windings might get undetected, but then there will definitely be a motor overheating issue. Another issue could be one of the bearings, but then again the bearing would start overheating. If neither of the bearings on either motor is overheating, do not worry about it. There are cases where motors create weird sounds but run with no issues for years.
Try cleaning motor fan with compressed air (turn the motor OFF before doing it). Dust that got stuck on the fan blades/air ducts can produce weird noise. Also visually inspect fan and air ducts for any debris that might got sucked inside the motor fan housing. Debris may obstruct air flow and thus create noise.

Sounds like a local train departed station😂😂
ur not gonna believe this...
freqency changers and 3phase induction motors,reality of modern trains and trams...
@george911751 yes I know...nowdays these 3 phase motors are used in modern trains
Yup, subway sound
Exactly what I was thinking!

It was but a soft starter but fc
However, as soft starters have more electronic components such as igbts , it creates harmonics which need additional filters.
Also prevents bursting pipelines due to sudden pressures when starting up pumps
Soft start are less energy efficient though. So there should always be a good reason to have soft start over variable speed drives as they are the most energy efficient.

So smooth.

That's a big fan.
Only true fans will appreciate it 😁
Big fan of what? 😁
For you
I'm a big fan of this big fan
I'm a big fan of that big fan
Damn starting sounds alot like ONIX traction motors by Alstom.
Damn you beat me to it
Reminds me of the Induced Draft fans I used to do laser alignment and balancing on.
*Przy rozruchu silnika to światła gasną* 😎👍
Great job!
Amazing sound.Thanks for posting this.
I'm a FAN of this.
Sounds like a jet engine powering up
🫵👍
love that sound. we have one that's a bit smaller around 150kW its got a soft start and still gets the the 500kW generator to make some smoke.
Holy shit this sounds so good.
Sounds like a hybrid race car starting up the v8
Wow music to my ears
That’s a big boy fan
Nice fan
This is true music !
how does the soft starter work?
That sounds more like a VFD start than a soft start.

The start sounded like a tornado siren, actually air raid siren because its so loud
what you hear when you click microsoft edge on your slow ass wooden PC
I worked as a pump station operator, that noise makes me sleepy all the time 😂
What purpose it have?
Why does this actually sound like I'm standing on a Subway platform underground and the train just started up? It's like it's rushing past me and I hear it echoing down the tunnel and getting more reverb as it fades away

Rare footage of the PS4 fan outside of the enclosure
Hell yeah
Он стартует как современный поезд метро
What are these kind of fans used for?
who would need this type of motor
Mmmm i love the sound of big brushless motirs spooling up with nothing attached... 🤤
2 questions:
1] What is the motor code on this thing - must be at least a J
2] Nobody bends 4/0 like that entrance - looks like rubber cord or welding cable - what is it?
How electronic and soft
which factory produces such engines?
It's 10 pm here... Idk why I watch this video
where is it using?
Just clicked this to let you know that I read the title as a "soft shart"
Dunno why. Quite stoned and it's late I suppose
Anyway, cool fan
Heheheheh
Let me have guess on what is this fan for: pumping air into some mining plane.
I don't recall how big some of our fans are. I just remember standing in the plenum! It was a big gymnasium size room. There were 4 fans feeding directly into it.
So all this time, it has been just the motors, not the wheels and rails!
Im guessing this is a vent fan at the same potato starch plant as the previous startup videos.
If to pumps always running, but there is different sound between this two one of them have like Winding sound what do you think it is winding problem?
If you can give me the answer please, and thank you sir
Harmonics

probably for a cooling tower
now i want to see it hard started
Yeah direct-on-line dammit! :)
What VVVF inverter is it using?
Is a soft starter
No its an inverter then initial whine gives it away@@patricioharriague1757
A good one!
Nikola sent me.
"mr. zulu initiate warp jump"
I wonder if i could install one on a air compressor so a power inverter could handle the startup surge
They make soft starts for air conditioner compressors for that same purpose so I would say yeah
metro?
who needs 500kW of fan power? what does 500kv of fan power even look like? Is it for a wind tunnel?? For Indoor skydiving?
what's it for
It could be very hot temperature.
Сколько там меди..
for 99% this motor is started by VFD (Frequency drive) not soft starter. You can hear high frequency IGBT switching noise at beginning
What is this fan used for?
Fanning
Our 500 kW Fan's is not starting like that.
aka a VFD.
ı need this for cool my pc
POV: universal non magnet rides
Siemens Velaro departing sounds.
Since this is the way a "soft" start sounds, I wonder how a "hard" start sounds ? ( jk )
It sounds very angry and to please it needs the electricity from the entire city block
imagine being at a complete stop and slamming your gas pedal but like.... with electricity
インバータ？
How many CFM on that bad boy 🤔
all of it
"its on idle" ☠️
Ev car sound😂
Nothing like first in rush current wich even bends construction beams ❤
No inrush there. Smooth acceleration.
@@billmoran3812 Unfortunately you're right... This was memorial comment on old times wich are ruined by softstarters 😪

Why it sounds like a frequency drive?

i want to see a hard start lol

voltage is probably being stepped up and this is no more than 300A if i had to guess
PS4 be like
Ev swap miata time
My Ps4:
No such thing is needed for the kitchen ventilation fan switch.
If makes power to make highter spining it makes loud sound but done with power is spinning max hes not loud then....
Meh, sounds pretty much like our wood mill exhaust system starting up 🎉
Except this motor has more than 600 hp
Anyone 2024 (it sound like a Boeing 747 engine) edit (is anyone bored so they pick this video)
Need this for Intel Arc
