Dyson Vacuum

OK...just seen the Dyson ad on the TV and they make a huge thing out of the 'Digital Motor' in their new cleaners.
Would someone care to explain what a digital motor is and how it works.......:scratch:

Probably a high-power induction motor controlled electronically for torque?

That reference to carbon emmissions is a joke, right?

[jantheman]

No joke...its on their website.....

My point is this...I can see how a motor is 'digitally controlled' but a 'digital motor' is another thing entirely and I'm having problems coming to grips with how it works.

[DSJR]

For an induction motor to spin at 100,000rpm is no mean feat - a 301 motor is more like 1500rpm I think. It looks as if it's driven by pulses, so this may be the "digital" bit - a goodly amount of techno-spin (sorry) on the description methinks ;)

I like Dysons, accepting that the plasticky nature of the products puts some people off. very please with our two, which use Panasonic motors I think..

I'd take it all with a huge dose of salt Ray :eyebrows: If they can advertise that particals of carbon are going to cause atmospheric polution & add to the greenhouse effect then no doubt governbents will soon be banning pencils due to the graphite content :D

What a load of sh*t :rolleyes:

[DSJR]

Tongue in cheek methinks, but not untrue, as motor brushes do wear over the years :)

I agree they do wear but to describe it as carbon emissions is down right misleading in that the term 'carbon emissions' is normally used in an entirely different context and for an entirely diferent 'type' of carbon.

[shane]

It's probably the only true instance of actual carbon emission, ie ejection of pure carbon. Everything else should really be called carbon compound emission.

Having said that, about the only harmful effect of this sort of carbon emission is the black marks all over everything when you put new brushes in.

You won't find them being used in a commercial environment.
I would get something that will last 20 years or far longer and do a fantastic job.
Not something you have to replace every couple years.

I suppose the motor is digital to the extent that it can be either 'off' or 'on'

Now, this is getting complicated...:lolsign::lolsign:

There was an Horizon (I think) show on recently, the subject being Quantum Mechanics, and there was a guy who'd invented a Quantum CPU

With 3 states!!! Off, On, and Both Off & On at the same time :scratch:

But like all things with Quantum Mechanics, the act of observing it changes the outcome :scratch::scratch:

Now that made me chuckle! So ... a warm 'thank you'

Always a pleasure, Howard;)

It has a Digital to Analog dirt converter that converts analog dirt to digital dirt then compresses the dirt for more dirt storage in the same size recovery container.
Giving you an digital MP3 dirt bag.

Here is a vacuum cleaner.
The best $250.00 U.S. you will ever spend.
