Abstract :
A novel design of axial flux magnetic gear adopting L-type ferromagnetic pole pieces and spoke-type ferrite magnet arrangement is proposed. This design not only decreases the flux leakage but also improves the torque density. A prototype is fabricated using the 3D printing process to verity the computed torque characteristics obtained by 3D FEM.
