Summary:This paper studies the application of Halbach array in optimal design of Permanent Magnet Synchronous Motors (PMSM). First, the paper demonstrates the intrinsic sinusoidal magnetic field and one-side magnetic shielding effect produced by Halbach array in FEM. Afterward, a serious of Halbach motor models based on different segment numbers per pole are established combined with Ansoft. Next, the waveform and harmonic contents of air-gap flux density are analysed. Then, the relationship between the segment numbers per pole and cogging torque are explored. Finally, the power-angle curves for coreless/core rotors are contrasted. The above results explain why and how Halbach array can be applied in PMSM design to reduce harmonic components for air-gap flux density, increase power density and decrease moment of inertia.
