Study of Axial Flux Stator Structures in Additive Manufacturing Material and Soft Magnetic Composite

Ferromagnetic additive manufacturing materials show promising design solutions for electrical devices. On the other hand, their high magnetic performance is limited by significant eddy current losses. A possible solution to this issue involves modifying or laminating the magnetic core to reduce iron losses. In this context, several stator structures of an axial flux motor are examined through a dedicated model to evaluate 3D iron losses. The developed model is validated using experimental tests performed on a soft magnetic composite stator.
