BLDC motors are often specified to maximize efficiency and torque density, and open rotor designs can further extend these capabilities.

The cLEAN motor maintains IE5 efficiency and runs up to 80 degrees Celsius cooler than a standard induction motor, said ...

Unlike his previous radial flux gearbox, which used a pair of magnet-studded cylindrical rotors nested one inside the other, this design has a pair of disc-shaped printed rotors that face each ...
