N2 - Since vehicle traction motors consume a lot of power and energy, high efficiency, power factor, and power density are required. Axial Flux Permanent Magnet Motor (AFPMM) is suitable as a traction motor for electric vehicles because it has high power density. In this paper, Soft Magnetic Composite (SMC) core and Nd bonded magnet are applied to Double Rotor Axial Flux Permanent Magnet Motor for electric vehicle traction motor to reduce losses and design a motor with high efficiency and power density. The soft magnetic composite used in this paper is suitable as a core material for the AFPMM because the powder has uniform magnetic properties in each direction and enables three-dimensional powder molding. In addition, Nd-bonded permanent magnets with high resistivity were applied for high efficiency, but due to their lower residual magnetic flux density and coercive force than Nd sintered permanent magnets, it is essential to improve electromagnetic performance and design to prevent permanent magnet irreversible demagnetization. In this paper, the sensitivity of the electromagnetic field performance according to the shape parameters of AFPMM designed using Nd-based bonded permanent magnets with high resistivity and SMC cores capable of 3D powder molding is analyzed. A model is proposed first through 3D-based finite element analysis, and the final model is proposed by designing the model to prevent permanent magnet irreversible demagnetization.
