Dyson digital motors

Michael Faraday discovered electromagnetic induction, the principle behind the electric motor, in 1831. Yet, despite being technologically advanced at the time, electric motors have changed very little since. Bulky, old-fashioned components and lots of moving parts prone to failure. Dyson engineers wanted to change all that.

Dyson engineers have spent a decade developing new types of highly efficient digital motors. The Dyson digital motor is smaller, lighter, cleaner and more power-efficient than conventional electric motors.

The problem with conventional motors

Conventional A/C motors use big, fragile fans, copper windings and brushes that wear out easily, making them inefficient and unreliable. And as the carbon brushes wear down, they emit carbon particles, which is bad for the environment.

Dyson digital motors

Dyson digital motors use digital pulse technology, spinning at up to 104,000 times a minute (five times faster than a racing car engine). They are incredibly efficient too – due in part to high tolerances. For example, the impeller spins at over 600mph with only 0.3mm clearance between the blade tip and the impeller housing. And no carbon brushes means no carbon particle emissions.

Dyson Airblade™ hand dryer

The Dyson digital motor in the Dyson Airblade™ hand dryer sucks in 37 litres of washroom air every second, pulls it through a HEPA filter, then forces it out through two continuous apertures the width of an eyelash. This generates sheets of air travelling at 400mph, to dry hands in just 10 seconds.

Dyson DC22 in the US

The DC22 is one of Dyson's newest American machines. Powered by a Dyson digital motor version, it's 1/3 smaller than a full-size Dyson machine, lighter and easier to store - but with no compromise on pick-up.

DC30

Dyson D30 and DC31 handhelds

The Dyson digital motor powers our latest battery operated handhelds, DC30 and DC31. The key to its superiority is its power efficiency. The latest Dyson digital motor is three times faster and more power efficient than any other - meaning Dyson's new handhelds can deliver twice the airwatts for the same run time.
