Development of Integrated Soft Magnetic Composite Core with Double Flanges for Improving the Performance of Axial Flux Motor

The demand for motors is increasing, and the needs for down-sizing, weight-saving and higher efficiency of motors are increasing with the progress of electrification of mobility, and improving efficiency of home appliances and industrial equipment. Axial flux motor (AFM) exhibits higher torque with thin shape than radial gap motors, and are attracting attention that meet these needs. For AFM, it is important to form a three-dimensional magnetic circuit, and Soft magnetic composite core (SMC) with high design flexibility in shape is suitable. In this study, in order to increase the opposing area between the stator and rotor, contributing to improved magnetic properties and increasing productivity, we will report on development of core shape that allows a teeth and double flanges to be integrally molded using SMC.
