An Axial Magnetic Gear With Improved Torque Density and Reduced Cogging Torque
Iranian Journal of Electrical and Electronic Engineering, 2021 A new axial magnetic gear (AMG) with enhanced torque density and reduced cogging torque is proposed in this paper. In the new structure, the direction and width of permanent magnets in high-speed rotor are changed and permanent magnets are removed from the modulator while the low-speed rotor remains unchanged.
