Dyson digital motors

In 1831, Michael Faraday discovered electromagnetic induction, the principle behind the electric motor. Yet, despite being technologically advanced for the time, electric motors had changed very little since the 19th century, and still had bulky, old-fashioned components and lots of moving parts prone to failure.

 

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 into the air.

The Dyson digital motor uses digital pulse technology, spinning at up to 88,000 times a minute (five times faster than a racing car engine). It’s incredibly efficient too, due in part to high tolerances. For example, the impeller spins at up to 600mph with only 0.3mm clearance between the blade tip and the impeller housing. And no carbon brushes means no carbon particle emissions and nothing to wear out.
