copper wiring. This means that machinery designed to automate
the twisting of the copper wires can be eliminated from the motor
manufacturing process and replaced by fabless, fully automated
PCB manufacturing. This major shift in the process drastically

can be more than four times higher than machines with traditional iron laminations and copper windings, says the company,
substantially reducing the copper mass for the same current
rating. The company's design algorithm allows it to design and
produce stators with virtually any dimension, so motor diameter
and length can be increased or decreased as desired.

between the rotor and the stator and negligible torque ripple
due to the absence of reluctance torque. The normal magnetic

such a way as to reduce the reluctance of the magnetic path. As
