A radially inserted permanent-magnet magnetic coupling design based on 3D printing

This paper investigates the radial inserted permanent magnet magnetic coupling design based on additive manufacturing (namely 3D printing). 3D printing prevents the use of adhesives or rivets in the manufacturing process of integrating the main structure; thus, the flux leakage is cut down compared with traditional magnetic coupling. Likewise, a honeycomb structure is applied to the shoe parts of the proposed magnetic coupling design to decrease the flux leakage and achieve a higher transmission torque.
