摘要	This paper investigates a novel design of the axial flux type magnetic gears that adopts L-type ferromagnetic pole pieces and spoketype ferrite magnet arrangement. This design not only decreases flux leakage, but also improves torque density. The three-dimensional (3D) finite element analysis is employed to compute the magnetic and torque characteristics of the three-dimensional design. Moreover, a newly developed 3D printing process is introduced to overcome the fabrication difficulty and expedite the manufacture process. A prototype of this novel magnetic gear design approach is given to verify the simulation result and the feasibility of the proposed 3D printing approach.
