摘要

A three-dimensional (3-D) analytical model with a high computational efficiency is proposed for a surface-inset axial flux machine (SIAFM). Accounting for the air-gap fringing field, the proposed 3-D analytical model is used to compute the magnetic field in the SIAFMs with conventional, Hat- and T-shaped Halbach arrangements. Based on the linear superposition method, the 3-D scalar potential equations for different regions with boundary condition equations are obtained. On this basis, the air-gap magnetic field and electromagnetic parameters can be derived. To demonstrate the advantages, the optimization performance of the T-shaped Halbach machine model is compared with that of conventional and Hat-shaped Halbach machine models. The prediction indicates that the optimized T-shaped Halbach machine model has the greatest electromagnetic torque. Finally, a 3-D finite element analysis (FEA) validates the 3-D analytical predictions.
