On the eve of the 2020 Rolex 24 at Daytona, the Automobile Club de l’Ouest (ACO), the sanctioning body behind the 24 Hours of Le Mans, and the International Motor Sports Association (IMSA ...

The prototype was made from 3-D printed plastic, copper wires and a steel rotor and tested using a variety of meters to measure power and a laser tachometer to determine the motor’s rotational ...

giving the rotor a little boost. The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs.

To avoid these core losses, DeepDrive’s motor replaces the stationary stator with a second rotor. The outer rotor resembles a cake pan and spins simultaneously with a ring-shaped internal rotor.
