Rotor Losses Measurements in an Axial Flux Permanent Magnet Machine
IEEE Transactions on Energy Conversion, 2011 MMF space harmonics and slot openings produce considerable rotor losses in permanent magnet (PM) machines, especially if fractional-slot windings are adopted. This paper aims to measure the rotor losses of a 12-slot 10-pole axial flux phase modulation machine. Both MMF space harmonics and slot openings are considered.

Nonlinear Semianalytical Model for Axial Flux Permanent-Magnet Machine
IEEE Transactions on Industrial Electronics, 2022This paper proposes a novel nonlinear semi-analytical model (AM) for the magnetic field calculation of electric machines. The nonlinear properties and local saturation effect of the iron part are taken into consideration in Cartesian coordinates, which is the main contribution of the proposed model. Thus, high accuracy of electro-magnetic field results

On the Use of Magnetic Wedges in Axial Flux Permanent Magnet Machines
IEEE Transactions on Industrial Electronics, 2013Axial flux permanent magnet (AFPM) machines are being increasingly used in a variety of industrial direct drive applications which benefit from their extreme axial compactness. In particular, slotted AFPM machines are of great interest since they allow to achieve high torque densities together with an acceptable constant power speed range.

Modeling of Axial Flux Permanent-Magnet Machines
IEEE Transactions on Industry Applications, 2004In modeling axial field machines, three-dimensional (3-D) finite-element method (FEM) models are required in accurate computations. However, 3-D FEM analysis is generally too time consuming in industrial use. In order to evaluate the performance of the axial flux machine rapidly, an analytical design program that uses quasi-3-D computation is developed.

Influence of magnetic wedges on the no-load performance of axial flux permanent magnet machines
2010 IEEE International Symposium on Industrial Electronics, 2010Aim of the paper is to evaluate a particular aspect of the design of axial flux permanent magnet (AFPM) machines, i.e. the use of SMC wedges to close stator slots. This contribution is the continuation of a previous investigation dedicated to the analysis of the no-load performance variation introduced by the magnetic wedges. Here, attention is focused
