Development of Soft Magnetic Composite Cores with Double Pole Shoes to Enhance the Performance of Axial Flux Motors
Sumitomo Electric Industries, Ltd.
This component is the stator core for an Axial Flux Motor (AFM) used in air cleaners. In response to the increasing emphasis on miniaturization, weight reduction, and high efficiency of motors in recent years, AFM that can achieve both thinness and high torque, is attracting attention and is expected to become widespread and replacing conventional radial flux motors made of Laminated Steel Sheets (LSS), which have the disadvantage of reducing torque when they are made thinner due to their motor structure. Compared to LSS, soft magnetic composite cores (SMC) are suitable for the three-dimensional magnetic circuit required for AFM due to their magnetic isotropic properties and high design flexibility in shape.
