Nonlinear Semianalytical Model for Axial Flux Permanent-Magnet Machine

In this article, we propose a novel nonlinear semianalytical model (AM) for the magnetic field calculation of electric machines. The properties and local saturation effect iron part are taken into consideration in Cartesian coordinates, which is main contribution proposed model. Thus, high accuracy electromagnetic results can be obtained with low computational time cost. developed based on harmonic modeling technique by solving Maxwell's equations. detailed theoretical derivations, use complex Fourier series Cauchy product, presented. To verify model, an axial flux permanent-magnet (PM) machine selected to investigated. Both finite-element experimental agree well that Moreover, AM has potential application other types PM electrical motor such as flat linear
