tl;dr 99,13%
Thank.
Too swedish, didnt read
95 ton, 76 000hp electric motor. i feel like that may be important context.
I'm planning on installing one on my bike.
I thought about using it in a hairdryer
No, it's the other way around: you actually install your bike on that motor
I see many people here interested in what it is actually used for
Which DeepL loosely translates to
The motor is going to a steelwork in India.

Big motor means big conductor means exponentially less resistive losses. More volume to disappate heat. Big motor has more core laminations which means less reactive losses.
Big motor is very expensive.
Eli5: Ty.
Jokes aside. What do they use it for?
From the article: The customer is a factory in India.
It is apparently saving the energy equivalent to 10 000 cars for a year.
I guess ships? Or to spin a dynamo to create electricity /s
The article says its for an "air-separation-unit", "luftseparationsenhet". For a steel factory in india
Maybe a diesel electric ship? Idk
It’ll last 25 years minimum, save 57,000,000 kronor (~6,000,000 usd), and reduce co2 generation equivalent to 10,000 cars. Neat!
I don't understand if it's 10,000 over calculated years (i.e. a bit more than one per day) or if it's 10,000 cars per year (i.e. 250,000 in total). I'm guessing the later
I also read it as the total CO2 emission reduction over its lifetime is 45000 tons which equates to the emissions of 10000 cars for one year, but the article leaves it a bit ambiguous.
Great news
