3D Hybrid Model of the Axial Flux Motor Accounting Magnet Shape
Résumé
This paper presents a generalization of an analytical model of an axial flux permanent magnet machine to any magnet shape. It uses an existing model which computes the 3D magnetic flux density by the separation of variables and finite difference method. The original magnet shape is modified by adding a radial dependence to the arc pole. It will be shown that this radial dependency has no impact on the problem's resolution. As an example, the model will be computed for a circular magnet shape and will be compared to a finite element analysis. Index Terms-Axial flux, finite difference method, Fourier series, magnetic scalar potential, magnet shape, permanent magnet, separation of variables.
