FEM evaluation of performance of axial flux slotted permanent magnet machines
Conference Record of 1998 IEEE Industry Applications Conference. Thirty-Third IAS Annual Meeting (Cat. No.98CH36242), 2002Axial-flux permanent magnet machines with slotted windings exhibit a significant cogging torque due to the magnetic anisotropy of the stator. The same produces a harmonic content in machine back EMF. The paper introduces and discusses a simple and powerful FEM algorithm that gives a numerical evaluation of both cogging torque and back EMF.

Analysis of Axial-Flux Halbach Permanent-Magnet Machine
IEEE Transactions on Magnetics, 2015This paper presents a 3-D analytical magnetic field analysis of an air-cored axial-flux Halbach permanent-magnet machine (AFPMM with Halbach). The 3-D analytical magnetic distribution is established using the magnetic scalar potential and modified BESSEL functions in the cylindrical coordinate system. The analytical magnetic field distributions and the

Electromagnetic design of axial-flux permanent magnet machines
IEE Proceedings - Electric Power Applications, 2004A general, analytic approach to the calculation of magnet fields in a slottless, axial-flux, permanent magnet generator is presented. The basic 'building block' is the vector potential produced by a current sheet situated between two, infinitely permeable, iron surfaces.

Thermal modelling of an axial flux permanent magnet machine
Applied Thermal Engineering, 2004Abstract The imperative for conserving energy highlights the need for considering the more widespread implementation of higher efficiency electric machines such as the axial flux permanent magnet (AFPM) machine. Because of their compact geometry and high power densities, the cooling of these machines is important.

No-Load Performance of Axial Flux Permanent Magnet Machines Mounting Magnetic Wedges
IEEE Transactions on Industrial Electronics, 2012Axial 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 adequate constant power speed range.

Application of flux reversal principle for axial flux permanent magnet machines
Journal of Applied Physics, 2008Applications of flux reversal machine can be found both for linear and radial flux machines. For axial flux machines, only one application is reported considering a two phase machine. In general, flux reversal effect can produce higher back electromotive forces than other topologies for the less amount of permanent magnets and thus can increase the ...
