Dyson Digital Motor
Michael Faraday invented the first electric motor in 1831 and its design has remained largely unchanged ever since. Lots of moving parts and a big, fragile fan make them unreliable. And they release carbon particles as their brushes wear down.
Dyson engineers spent seven years developing a new type of motor. Half the size and weight, the Dyson digital motor spins 88,000 times a minute - five times faster than a Formula One car engine. Fewer moving parts also means it lasts four-times longer than ordinary motors.
So far, it's being used in all our cordless machines as well as the Dyson Airblade™ hand dryer.
