Endurance and Lifetime Assessment of PCB Stators

By etching copper coils directly onto the PCB stator, we eliminate the heavy steel core and copper windings of conventional motors. This not only reduces the size and weight by half, but by removing the iron in the magnet path we’ve eliminated torque ripple, cogging, stator hysteresis, and eddy current losses. The result is a significant increase in efficiency across all load conditions.
