This paper investigates a novel design of the axial flux-type magnetic gears that adopts L-type ferromagnetic pole pieces and spoke-type ferrite magnet arrangement. This design not only decreases flux leakage but also improves torque density. 3-D finite element analysis is employed to compute the magnetic and torque characteristics of the 3-D design. Moreover, a newly developed 3-D printing process...
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...
Synchronous reluctance motors (SynRM) have been widely used because of their excellent performance, such as high efficiency and accurate speed control. This paper focused on the efficiency and starting ability of SynRM. Based on the view of steel sheet material and motor fabrication, the iron loss influences on SynRM regarding different grades of silicon steel are compared, and the performance of...
