Technology.am (June 29, 2009) — Sir James Dyson has unveiled a hand-held vacuum cleaner which is run on “the fastest motor in the world”, ten times quicker than the engine of a Boeing 747 aircraft.

World's Fastest MotorThe DC 31 vacuum, which weighs 2.2lb, is the first ever domestic appliance to incorporate a so-called digital switched reluctance motor, which Sir James claims is the “fastest motor in the world.”

At 104,000 revolutions per minute, the motor turns ten times as fast as a commercial aircraft, five times as fast as a Formula 1 engine and more than twice as fast as the most powerful industrial milling machines.

The only thing quicker is a dentist’s drill, but that is technically a turbine, not a motor.

The digital motor is half the weight and size of a normal motor of the same power. The £129 hand-held vacuum cleaner will go on sale next month.

    You should make it clear that this is an electric motor, as Turbines typically run as fast as 150,000 rpm or more.
