    Just saw an add for the dyson hairdryer with 'new digital motor' ...

    How is a motor digital? Surely its mechanical or magnetic or i dont know, hydrolic ... but digital?

    Am I missing something?

    Marketing, Anything with circuitry is digital. State of on or off.

    Dyson is a triumph of marketing about design over actual result.

    Have one of their vacuum cleaners. Sure, Dyson tell us it's got this or that gadgetry...but give me a Henry any day.

    I love the the reviews on Amazon.co.uk https://www.amazon.co.uk/DYSON-Supersonic-Hair-Dryer-Fuchsia/dp/7178681896 you could say there is a slight division of opinion.

    Posting a thread asking if it electrical or is it not?

    Surely you're just splitting hairs..

    Presumably it's to do with the motor PWM driver circuitry which would allow a high degree of control of the acceleration and speed of the motor. Whether that's needed in a hair dryer is debatable. All brushless DC motors require controllers similar to this so it's mostly a marketing term?

    I can remember one hammer drill with electronic speed control. It had ONE diode, that's the least number of electronic components you can have in a circuit.

    And any marketer who uses "digital" on a TV aerial deserves to have one inserted.

    Anywhere I've looked says brushless DC with a neodymium magnet core, same as the other digital motors? What is it so?

    As far as I know the dyson hairdryer doesn't make any noise

    I suspect the technology for this soundless digital air jet may come from the same technology that powers the soundless digital air jet drone devices what have been bombing mountain shepherds and weddings the last few years.

    I wonder if it's silent and dries your hair in 3 seconds

    Probably uses a digital plug too and can only be used with a fully digital hair brush.

    All marketing spiel....
    I saw an ad earlier saying for so much euro a month donated you can adopt a tiger (Charity shi*e like) But then thought well hold on, if 10,000 people all gave €5 euro a month then how many times over is a tiger adopted? :pac:
    In fact, what in the blue hell is so called "adopting" an animal with a charity in this case? :pac: It's not like I am rescuing him from the local pound and he comes to live in my back garden (that's adopting)


    Marketing brilliance when you think about it.

    My hairdresser (freelance, comes to my house) bought a dyson recently and I asked her to dry my hair with it since I was really curious. It is not remotely silent. Its a bit quieter than a typical salon hair dryer, but silent is a nonsense.

    It did work nicely, my hair felt very soft after it and its nice a lightweight, but at €400, no way could I justify it.

    The term "digital motor" appears to have been invented by Dyson for marketing purposes. The fundamental principal is the same as for all other electromagnetic motors. The specific type of motor used by Dyson has permanent magnets in the rotor and is called a brushless DC motor or a permanent-magnet synchronous motor.

    Agreed. We have a Dyson DC29 vacuum cleaner and it is by far the best vacuum cleaner we have ever had.
    But it was a wedding gift so did not have to pay for it.

    Our fridge has a digital inverter. I know this because they felt the need to write it on front.

    I think you'll find they don't only bomb weddings and shepherds, they have conered the market in bombing schools too.
