摘要

Considering the 3-dimensional (3D) air-gap fringing field, unified 3D analytical models equivalent to linear machines are proposed for surface-inserted axial flux machines (SIAFMs) with odd-/even-piece Halbach arrangements. The 3D scalar potential governing equations for several regions can be uniquely solved according to Fourier decomposition coefficient matrixes derived from field boundary conditions. Based on this, the electromagnetic parameters can be derived. Predictions indicate that, compared with the non-optimized SIAFMs with three-/four-piece Halbach arrangements, the optimized SIAFMs with three-/four-piece Halbach arrangements exhibit excellent electromagnetic performances. The 3D finite element (FE) and analytical predictions for the SIAFM models are compared.
