  • Apparatus and method for cogging torque reduction with rotor embedded cylindroid permanent magnets
    Patent number: 10734874
    Abstract: A rotor supports embedded cylindroid permanent magnets, extending parallel to the rotor axis, and transversely magnetized with a respective magnetization direction radial to the rotor axis. The rotor is concentric to an inner stator and an outer stator. The embedded cylindroid permanent magnets include an arcuate surface facing the outer stator teeth concurrent with an arcuate surface facing the inner stator teeth.
