Characteristics of soft magnetic composites and application in new structure motor

Soft magnetic composites (SMCs) is a new kind of powder metal material. Compared with the traditional silicon steel material, it has the advantages of low eddy current loss, isotropic magnetic conductivity and thermal conductivity, easy to make parts with complex structure, and is suitable for motor core materials, especially in high-frequency working conditions. This paper introduces the characteristics of SMCs, and classifies the application of the material in the motor, and finally discusses the shortcomings and the development directions.
