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 have spent a decade developing a new type 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, limiting efficiency and reliability. 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 emissions.
