Dyson's New Vacuum Driven By the Fastest Motor Ever

If the diameter was really 55m, the outer edge would be going 1/1000th the speed of light :)

Well, if I was in the market, I'd still buy american (presumably oreck is still made over here), but if they put out a blender, I'll take it.

Dyson is the worlds best vacuum cleaner salesman. He makes pumps on sticks to suck up dust of carpets that are slightly better than other pumps on sticks. He's a salesman not an engineer.

Nosilverman, good point -- should say 55mm.

Yeah I was thinking... a 55 meter vaccuum? lol.

And Geebob, your choice between Dyson and Oreck is a choice between buying Malaysian or Chinese, so take your pick.

and Dancupid, apparently his skills as a salesman are more important than his skills as an engineer, I mean thats great if you can build a nice motor, but if you can't sell it than your engineering skills don't amount to much.

Hey is this blog like really hard to edit or something? It seems the writers always post their mistakes in the comments without fixing it in the article....

how many prototypes did he make til he made the final product?

That is awesome. But does it create more suction than the previous models? I already have one of his original models, and love it. If the outer edge of the fan is spinning that fast I can assume its making some ultra high pitch sound, that humans can't hear, but may torture every pet in your neighborhood.

Scale the electric motor up to jet aircraft size, add it to a jet engine where the heat from the jet engine exhaust does most the work power it from a alternator run off the jet engine then you would have a very efficient jet engine. Don't know if it is possible to piggyback an electric motor with a fuel oil type jet engine this way but think of the possibilities.

If that works then try it on a inefficient automobile engine, one that may also be used to recharge the batteries in a plug in electric/gas hybrid. It is easy thinking of these ideas but much harder to get them to work the way you want.

If you made this bigger you could build the words fastest car.

Many people who profess a certain degree of intelligence when posting comments should learn to spell or at least use some sort of spell checker before posting their comments.
e.g. bdhoro87 (sic) I mean thats (should be that's) great if you can build a nice motor, but if you can't sell it than (should be then) your engineering skills don't amount to much.

I see this sort of thing on many a web page. It shows lack of attention to detail and an "I don't care what people think of me, I just want them to know what I think of them" attitude.

Get an education before you start criticizing others

jackmor48 - Lighten up - Think of this as a conversation, not a high school English class.

Look at the big brain on jackmor48!! I bet you felt pretty good about yourself after posting that comment. So, do you spend all day trolling comments for grammatical and spelling errors? You've certainly earned the right with that superior education of yours. Go get'um buddy!!

Dude did u just correct an apostrophe? This is a friggin blog post not a high school essay. Did you really not understand the message? I'm not gonna use a spell checker on some stupid comment on a blog - I'm not a journalist.
Honestly screw you and your "education," out of all of us you sound like the idiot...
Your corrections aren't even correct... for your information "than" is used for a comparison, like I am smarter than you, or like my statement above, his business skills are more important than his engineering skills. "Then" is used to denote time, as in jackmor48 you can go screw yourself, and then go back school.

Get an education before you start criticizing others - your the one being critical (and sound like an idiot doing it).

Thes luks reely kool giys

---sorry dude but u forgot the "." I mean what the hell is wrong with u. Learn to properly end a sentence before you criticize others. :)

Actually Pratt and Whitney Canada has an engine whose ng1 is a little over 51,000 rpm .
so ten time faster then a jet engine is a stretch , 2 times as fast maybe.

First of, how can a motor run faster than a motor?

Quote: "At 104,000 rpm, the DC31's digital switched reluctance motor actually spins faster than any motor on earth."

Second, how about dental drills? Airtubines doing over 500000rpm

Thierd:

Quote:"The motor draws only 200 watts (about half the power needed for a typical vacuum motor), does not emit any carbon dust, won't wear out as fast, and puts your high-end blender to shame."

If it only draws half the power, it only delivers hald the work. No free lunch! If they talked about a effiency increase of 100% then the motor produces the samw work.

Shotty journalism!

Sorry for the misspellings.
But then again My Engish might just be a tad better than Your Danish!

RE: scaling larger

I don't know that it would scale up too well. I think the larger the motor, the more weight/stress on the moving parts and it would tear itself apart.

All this talk about motors and performance is fun, BUT, I have a cheap vacuum that has TOO MUCH suction. I had to block off the air intake with duct tape so it would stop lifting the carpet off the floor. The box it came in clearly boasts that it draws 12 amps or something. Really? A point of pride?

So this focus on MORE suction is ridiculous. I wish engineers and sales departments would focus on what is important to the consumer instead of just out-performing the competition. I want products that are: easy to use, light weight, very reliable, easy to service (by the consumer), long-lasting and use less energy. Lots of adjustments are nice too. So 104,000 RPM does not impress me at all as far as vacuums are concerned.

quarque has a good point, and I'd like to say that the motor probably could be used more effectively in something else like a fireman's saw, or remote control vehicles. Gemcutting or sanding, my dremel tool, small centrifuges or for mixing chemicals. Possibly a small device to filter blood for dialysis at home? Is it fast enough to machine titanium? Hard disk drive speed, gyroscopes. I'm pretty sure I could go on, but you get it.

Dyson never ceases to amaze does he ? With such technology being utilized with something as fundamental and simple as a vacuum, one can only imagine what this motor can achieve in different aspects of the future!

Interesting...I wonder if this motor could be used in an R/C aircraft? It might tak a lil' bit to get the electronics and power supply right, but it could be pretty cool (and fast) in a EDF jet.

I have a few ideas for that motor that doesn't involve cleaning floors. HEY MISTER DYSON, can I get my hands on one or three of those motors without buying the vacuum?... seriously.

I was happy to fix that for you, sir. Reads better my way, I believe.
