THE DYSON DIGITAL MOTOR V10
The smallest, lightest, yet strongest motor Dyson has ever produced. Its ceramic shaft is cured at 1,600°C to make it 3 times harder than steel, yet with half the density. With the impeller moved from the front of motor to the back, axial flow draws in cooler air to reduce the temperature and allow the motor to spin at up to 125,000 rpm. Which generates the suction power of a big vacuum.
