Electromagnetic design of a novel hybrid flux SMCs PMSM

The hybrid flux PMSM includes both axial flux and radial flux, so its design method is different from the traditional cylindrical permanent magnet synchronous motor. In this paper, based on the analysis of the structure and operation principle of the hybrid flux motor, the design principle of the motor is given. The authors study the effects of slotting, permanent magnet thickness, and pole-slot match on the motor and determine the important parameters of the motor. Finally, the finite element method is used to verify the electromagnetic performance of the motor, and the correctness of the proposed design principle is verified.

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.
