An Axial Flux-Focusing Magnetically Geared Motor
2017 IEEE Energy Conversion Congress and Exposition (ECCE)
In this paper an axial flux magnetic gear (AFMG) is proposed that has an integrated outer stator. This axial flux magnetically geared motor (AFMGM) is unique in that the stator shares the high-speed rotor with the AFMG, so there is no need for a separate rotor. The high speed and low speed rotors use a flux-focusing typology. The stator is mounted outside the AFMG and this makes the design mechanically less complex. It also enables the stator to be cooled more easily.
