N2 - The performance of the permanent magnet synchronous motors can be evaluated through several factors including power losses, harmonic content, and torque ripples. One of the possible ways to enhance the density of the output power and torque is by implementing the Halbach magnet array. It can improve the output performance of the electric machine by increasing the fundamental amplitude of the magnetic flux density and reducing the harmonic contents. So, a Modified Segmented Halbach Magnet Arrays (MSHMA) configuration is proposed and compared to the conventional topology in this paper. The static magnetic field distributions of the given Halbach magnet array structures are analyzed by the Finite Element Method (FEM) for a surface-mounted Permanent Magnet Synchronous Motor (PMSM). Also, the harmonic components of both configurations are evaluated by the Fast Fourier Transform (FFT). The results indicate that the MSHMA can significantly improve the output performance of the electric machine by increasing the fundamental amplitude of the magnetic flux density and reducing the harmonic contents. The electric machines model composed of the MSHMA and conventional topology are also simulated by the FEM, and the air-gap magnetic flux density distribution under the armature reaction is analyzed. The results show the MSHMA's capability to improve the output performance of the considered PMSM model, and a reduction in the torque ripple from 4.4 % to 1.8 %.
