chine the magnetic back iron (“stator-yoke”) is replaced by a second synchronously rotating rotor. While the iron length remains the same, the air gap area is doubled, eliminating the core losses in the stator yoke and offering more space for the magnets. Torsionally stiff, self-supporting wave winding   At the heart of the dual-rotor technology is the new winding, which supports the transmission of the generated torque through the stator. T...
