Hitachi unveils motor without "rare earths"

This is part of why I've always loved made in Japan tech. They will always be the world leaders in technology.

It would be great if the amount of copper and other rare earths could be significantly reduced in the making of devices without any sacrifices.

On a somewhat relevant note, what many thought was science fiction is actually not fiction at all.

Ah, I see what you did there! You are saying that Kuntry's have Vaginas. Hah-hah. I get it. Wait, whut?

korea didn't get hit with a tsunami

lack of info, is lacking info.

I always wondered why most motors were not already magnet-less. Not too hard to do.

China is trying to control the market of permanent magnets so it's definitely a good thing to find ways to not need them.

Umm...explain to me how you would make a brushless motor without any magnets.

Replace permanent magnet with electromagnet. Not really that hard. The tricky part is getting power to the rotating electromagnet if you don't want brushes but there are ways using induction and so on. Plenty of motors out there have brushes anyway, so while it's usually less desirable to have brushes, some motors do have em, such as vacuum cleaners. (typically)

Sure, brushes are fine if you don't care about efficiency or reliability. Inductive power transfer is also a huge hit to efficiency.

Rare earths are used to make a wide range of high tech products, including powerful magnets, batteries, LED lights, electric cars, iPods, lasers, wind turbines and missiles.

LOL I like how they had to throw in a popular consumer product in order to get people to relate to the article.

LOL! The USA is still number one when it comes to inventing new technology.

And what exactly would that be? The article has exactly 0 details on what they did... why didn't I think of that?!

Japan will alway be the world leaders in tentacle pron

And it isn't even close at that!

wrong, the article clearly states that they made a motor which contains no rare earth elements. think of the simplest possible explanation...

lol sony phones

That's easy...

Many a motor has been made without "rare earths".
Ceramic magnets are in millions of PM motors for decades! 😛

If a motor could speak ever wonder what kind of question it would ask?
I believe it would say to the controller "Watts for lunch?" :biggrin:

Hmm, if you were to hook up the motor to a PA system, it could perhaps talk. :awe:
